To say that progress goes on and has gone on at unequal speed in
different continents, so far as human society is concerned, is so
self-evident as to be trite. Yet, after all, we hardly visualize even
this fact to ourselves; and we laymen, at least, often either disregard
or else frankly forget the further fact that this statement is equally
true as regards the prehistory of mankind and as regards the
paleontological history of the great beasts with which he has been
associated on the different continents during the last two or three
hundred thousand years. In history, a given century may on one continent
mean what on another continent was meant by a century that came a
thousand years before or a thousand years later. In prehistory and
paleontology there is the same geographical difference as regards the
rapidity of development in time.
The Soudan under the Mahdi at the end of the nineteenth century was in
religious, industrial, and social life, in fact in everything except
mere time, part of the evil Mohammedan world of the seventh century. It
had no relation to the contemporary body politic of humanity except that
of being a plague-spot. The Tasmanians, Bushmen, and Esquimaux of the
eighteenth century had nothing in common with the Europeans of their
day. Their kinship, physical and cultural, was with certain races of
Palæolithic Europeans and Asiatics fifty or a hundred thousand years
back.
In just the same way the fierce wild life of parts of Africa to-day has
nothing in common with what we now see in Europe and the Americas. Yet
in its general aspect, and in many of its most striking details, it
reproduces the life that once was, in Europe and in both the Americas,
in what paleontologists call the Pleistocene age. By Pleistocene is
meant that period—of incalculable length as we speak of historic time,
but a mere moment if we speak of geologic time—which witnessed in
Europe and Asia the slow change of the brute-like and but partly human
predecessors of man into beings who were culturally on a level with the
lower forms of the savages that still exist, and some of whom were
physically, as far as we can see, abreast of the more advanced races of
to-day.
Surely, this phase in the vast epic of life development on this planet
offers a fascinating study. The history of man himself is by far the
most absorbing of all histories, and it cannot be understood without
some knowledge of his prehistory. Moreover, the history of the rest of
the animal world also yields a drama of intense and vivid interest to
all scholars gifted with imagination. The two histories—the prehistory
of humanity and the history of the culminating phase of non-human
mammalian life—were interwoven during the dim ages when man was slowly
groping upward from the bestial to the half-divine.
It was my good fortune throughout one year of my life to roam, rifle in
hand, over the empty, sunlit African wastes, and at night to camp by
palm and thorn-tree on the banks of the African rivers. Day after day I
watched the thronging herds of wild creatures and the sly, furtive human
life of the wilderness. Often and often, as I so watched, my thoughts
went back through measureless time to the ages when the western lands,
where my people now dwell, and the northern lands of the eastern world,
where their remote forefathers once dwelt, were filled with just such a
wild life. In those days these far-back ancestors of ours led the same
lives of suspicion and vigilant cunning among the beasts of the forest
and plain that are now led by the wildest African savages. In that
immemorial past the beasts conditioned the lives of men, as they
conditioned the lives of one another; for the chief factors in man's
existence were then the living things upon which he preyed and the
fearsome creatures which sometimes made prey of him. Ages were to pass
before his mastery grew to such a point that the fanged things he once
had feared, and the hoofed things success in the chase of which had once
meant to him life or death, became negligible factors in his existence.
Some of the naked or half skin-clad savages whom I met and with whom I
hunted were still leading precisely the life of these ages-dead
forebears of ours. More than once I spent days in heavy forests at the
foot of equatorial mountains in company with small parties of 'Ndorobo
hunters. They were men of the deep woods, as stealthy and wary as any of
the woodland creatures. In each case they knew and trusted my
companion—who was in one instance a settler, a famous lion hunter, and
in the other a noted professional elephant hunter. Yet even so their
trust did not extend to letting a stranger like himself see their women
and children, who had retreated into some forest fastness from which we
were kept aloof. The men wore each a small fur cape over the shoulders.
Otherwise they were absolutely naked. Each carried a pouch, and a spear.
The spear head was of iron, obtained from some of the settled tribes.
Except this iron spear head, not one of their few belongings differed
from what it doubtless was long prior to the age of metals. They carried
bows, strung with zebra gut, and arrows of which the wooden tips were
poisoned. In one place Kermit found where a party of them had dwelt in a
cave, evidently for many weeks; there were bones and scraps of skin
without and within; and inside were beds of grass, and fire-sticks, and
a walled-off enclosure of branches in which their dogs had been penned.
Elsewhere we came on one or two camping-places with rude brush shelters.
Each little party consisted of a family, or perhaps temporarily of two
or three families. They did not cultivate the earth; they owned a few
dogs; and they lived on honey and game. They killed monkeys and hyraxes,
occasionally forest hog and bongo—a beautifully striped forest antelope
as big as a Jersey cow—and now and then elephant, rhino, and buffalo,
and, on the open plains at the edge of the forest, zebra. The zebra was
a favorite food; but they could only get at it when it left the open
plains and came among the bushes or to drink at the river. Two of these
wild hunters showed me the bones of an elephant they had killed in a pit
a long time previously; and the head man of those we had with us on
another trip bore the scars of frightful wounds inflicted by an angered
buffalo. Hyenas at times haunted the neighborhood, and after nightfall
might attempt to carry off a child or even a sleeping man. Very rarely
the hunters killed a leopard, and sometimes a leopard pounced on one of
them. The lion they feared greatly, but it did not enter the woods, and
they were in danger from it only if they ventured on the plain. The head
man above mentioned told us that once, when desperate with hunger, his
little tribe, or family group, had found a buffalo killed by a lion, and
had attacked and slain the lion, and then feasted on both it and the
buffalo. But on another occasion a lion had turned the tables and killed
two of their number. The father of one of my guides had been killed by
baboons; he had attacked a young one with a club, and the old males tore
him to pieces with their huge dog teeth. Death to the head of a family
in encounter with an elephant or rhino might mean literal starvation to
the weaker members. They were able to exist at all only because they had
developed their senses and powers to a degree that placed them level
with the creatures they dreaded or preyed upon. They climbed the huge
trees almost as well as the big black-and-white monkey. I had with me
gun-bearers from the hunting tribes of the plains, men accustomed to the
chase, but brought up in villages where there was tillage and where
goats and cattle were raised. These gun-bearers of mine were good
trackers and at home in the ordinary wilderness. But compared to these
true wild men of the forest they might almost as well have been
town-bred. The 'Ndorobo trackers would take me straight to some
particular tree or spot of ground, through miles of dense, steaming
woodland every rood of which looked like every other, returning with
unerring precision to a goal which my gun-bearers would have been as
helpless to find again as I was myself; and they interpreted trails and
signs and footprint-scrapes which we either hardly saw or else misread.
Doubtless the ancestors, or some of the ancestors, of these men had
lived in the land, just as they themselves now did, for untold
generations before the soil-tillers and cattle-owners came into it. They
had shrunk from the advent of the latter, and as a rule were found only
in isolated tracts which were useless for tillage or pasturage, the
dense forest forming their habitual dwelling-place and retreat of
safety. From the best hunting-grounds, those where the great game
teemed, they had been driven; yet these hunting-grounds were often
untenanted by human beings for much of the year, being visited only at
certain seasons by the cattle-owning nomads.
Often these hunting-grounds offered sights of wonder and enchantment.
Day after day I rode across them without seeing, from dawn to sundown, a
human being save the faithful black followers, hawk-eyed and
steel-thewed, who trudged behind me. Sometimes the plains were seas of
wind-rippled grass. Sometimes they were dotted with clumps of low
thorn-trees or broken by barren, boldly outlined hills. Our camp might
be pitched by a muddy pool, with only stunted thorns near by; or on the
edge of a shrunken river, under the dense shade of some great,
brilliantly green fig-tree; or in a grove of huge, flat-topped acacias
with yellow trunks and foliage like the most delicate lace; or where
the long fronds of palms moved with a ceaseless, dry rustle in the
evening breeze. At the drinking-holes, in pond or river, as the
afternoon waned, or occasionally after nightfall when the moon was
bright, I sometimes lay to see the game filing down to drink.
On these rides, I continually passed through, and while lying in ambush
I often saw, a wealth of wild life, in numbers and variety such as the
western world, and the cold-temperate regions of the Old World, have not
seen for many, many thousands of years. How many kinds of beasts there
were! Giraffes stared at us over the tops of the stunted thorn-trees. In
the dawn we saw hyenas shambling homeward after their night's prowl.
Wart-hogs as hideous as nightmares ploughed along with their fore knees
on the ground as they rooted it up. Sleek oryx with horns like rapiers
galloped off with even, gliding gait. Shaggy wildebeests curvetted and
plunged with a ferocity both ludicrous and sinister; elands as heavy as
prize cattle trotted away with shaking dewlaps. Ungainly hartebeests,
and topi whose skins had the sheen of satin, ran with smooth speed. The
lyre-horned waterbucks had the stately port of wapiti bulls. Rhinoceros,
foolish, mighty, and uncouth, stood half asleep in the bright sunlight.
Buffalo sought the shade of the thorn-trees, their bodies black and
their great horn-bosses glinting white. Hippos snorted and gambolled in
the water. Dominant always, wherever we saw them, were the lion and the
elephant; and the favorite prey of the lion was the zebra, the striped
wild horse of the African wastes.
Of course, these many different creatures were not all to be seen at any
one time or in any one place. But again and again there were so many of
them that we felt as if we were passing through a gigantic zoological
garden. Often the line of our burden-bearing carriers had to be shifted
from its point of march, to avoid a rhinoceros which stared at us with
dull and truculent curiosity; while the zebra herds filed off with
barking cries across the sunlit plain, and delicate gazelles, dainty as
wood-sprites, fled like shadows, and hartebeests gazed toward us with
long, homely faces; or we stopped to watch a herd of elephants, cows and
calves, browsing among the thorns, their curling trunks raised now and
then to test the wind, or perhaps one big ear lifted and then slapped
back against the body.
One day at noon, in the Sotik country of East Africa, we stopped to skin
a hyena which I had shot for the Smithsonian. As we skinned it the game
of the neighborhood gathered to look on. The spectators included
wildebeest, hartebeest, gazelle, topi, a zebra, and a rhinoceros—the
hook-lipped kind. Late that afternoon I shot a lioness; the successive
reports of the rifle and the grunting roars of the lioness, put to
flight a mixed herd of zebra and hartebeest which had hitherto been
unconcernedly grazing not far off to one side of the scene of action.
On another day as I journeyed along the valley of the Guaso Nyero—first
at the head of the safari, as it travelled through the green forest of
the river-bed, and then with only my gun-bearers, through the hot,
waterless, sun-scorched country back from the river—I saw rhino,
giraffe, buffalo, eland, oryx, waterbuck, impalla, big gazelle, and
gerenuk or giraffe-gazelle. After camping, toward evening, I walked
up-stream, away from the tents, until I came to a spot where the river
ran through a wild, rugged ravine. On the hither side I found the
carcass—little more than the skeleton—of a zebra which had been killed
by a couple of lions as it came to drink the previous night. It was
evidently a favorite drinking-place, for broad game trails led down to
the river at this point from both banks. As I sat and watched, a herd
of zebra approached cautiously from the opposite side. There were in it
representatives of two species of these gaudily marked wild horses or
wild asses, the common zebra and the much, bigger northern zebra with
longer ears and more numerous and narrower stripes. The herd advanced,
avoiding cover as much as possible, continually halting, once wheeling
and galloping back, ever seeking with eye and nostril some token of the
presence of their maned and tawny foe. At last the leader walked down
through a break in the bank to the river. The others crowded close
behind, jostling one another as they sank their muzzles in the water.
For a moment fear left them, and they satisfied their thirst, and those
that were through first then stood while the rearmost drank greedily.
But as soon as one of them began to move back to the shore the others
became uneasy and followed, and the whole herd broke into a gallop and
tore off for a couple of hundred yards. Looking at them it was easy
enough to bring before one's eyes the tragedy of the preceding night;
the herd nearing the water, wary, but not wary enough, the panic flight
as the lion dashed among them, the struggling and the neighing screams
of the victim before the great teeth found the life they sought. The
herd I watched was not assailed; it cantered off; oryx and waterbuck
came down to drink and also cantered off. The carcass of the murdered
zebra, little but bones and shreds of red sinew and scraps of skin, lay
not far from me. Footprints showed where the lions had drunk after
eating. As the long afternoon lights waned, a hyena, abroad earlier than
usual, began to call somewhere in the distance. The lonely gorge was
rather an eerie place as darkness fell, and I strode toward camp, alone,
keeping a sharp lookout round about; and as I walked and watched in a
present that might be dangerous, my thoughts went back through the
immeasurable ages to a past that was always dangerous; to the days when
our hairy and lowbrowed forefathers, under northern skies, fingered
their stone-headed axes as they lay among the rocks in just such a
ravine as that I had quitted, and gazed with mingled greed and terror as
the cave-lion struck down his prey and scattered the herds of wild
horses for whose flesh they themselves hungered.
Once in East Africa I stalked a hook-lipped rhino, a big bull with good
horns. I wished its skin and skeleton for the Smithsonian. When a
hundred and fifty yards off I stopped for a moment by an ant-hill and
looked around over the wide plain. There were in sight a couple of
giraffes, some solitary old wildebeest bulls, showing black against the
bleached yellow grass, and herds of hartebeest, topi, big and little
gazelle, and zebra. On another occasion, when with Kermit, we inspected
three rhinos at close quarters, came to the conclusion that none of them
would make good specimens, and backed off cautiously a couple of hundred
yards to a big ant-hill. From this point, there were in sight all the
kinds of game mentioned above except the giraffe and little gazelle, and
in addition there were ostrich and wart-hog.
One night when we were camped on the western bank of the upper White
Nile we heard a mighty chorus. Lions roared and elephants trumpeted, and
in the papyrus beds, beneath the low bluff on which our tents stood,
hippopotamus bellowed and blew like the exhaust-pipes of huge
steam-engines. Next day I hunted the giant square-mouth rhinoceros,
killing a cow and a bull, and taking their skins and the skeleton of one
for the Smithsonian. On the walk out, and but a mile or two from camp,
we had passed a small herd of elephants; and on our return we found them
in the same place, still resting, with many white cow-herons perched on
their backs. From where I stood looking at them hartebeest, kob,
waterbuck, and oribi were also all in sight.
I could mention day after day such as these, when we saw myriads of
game, often of many kinds. One afternoon of heat and sunlight on the
parched Kapiti plains, teeming with wild life, I followed a lion, on
horseback. During the gallop he ran for several minutes almost in the
middle of a mixed herd of hartebeest and zebra. When he came to bay, I
walked in on him. In the background the barren hills, "like giants at a
hunting lay." Bands of hartebeests and of showy zebras, joined by
grotesquely capering wildebeests and by lovely, long-horned gazelles,
stood round in a wide, irregular ring, to see their two foes fight to
the death. Another day, at burning noon, in a waste of sparsely
scattered, withered thorn-trees, west of Redjaf on the upper Nile, I
killed a magnificent giant eland bull; and during the hunt I saw
elephant, giraffe, buffalo, straw-colored Nile hartebeest, and roan
antelope, as big as horses, with shining coats which melted in ghostly
fashion into the shimmering heat haze of the dry landscape.
In short, for months my companions and I travelled and hunted in the
Pleistocene. Man and beasts alike were of types our own world knew only
in an incalculably remote past. My gun-bearers were really men such as
those of later Palæolithic times. Now and then I spent days with hunters
whose lives were led under conditions that the people of my race had not
faced for ages; probably not since before, certainly not since
immediately after, the close of the last glacial epoch. The number and
variety of the great game, the terror inspired by some of the beasts of
prey, the bulk and majesty of some of the beasts of the chase, were such
as are unknown in the rest of the modern world; and nothing like them
has been seen in the western and northern world since the Pleistocene.
Many of these great and beautiful beasts were of kinds which either have
developed in Africa itself, and have never wandered to the other
continents, or else had disappeared from these other continents before
man appeared upon the earth. But three of the most characteristic of
these beasts, the lion, the elephant, and the horse, were spread over
almost the whole of this planet at the time when man as man had fairly
begun his hunting. These three beasts then abounded in Europe and in
Asia, in North America, and in South America. In each of these
continents they were among the dominant types of a fauna as rich,
varied, and impressive as only that of Africa is to-day.
When I speak of "elephant," "lion," and "horse" I am speaking of the
beasts themselves, not their names in our vernacular. As regards two of
these three animals, the horse and the big horse-killing cat, we have no
common names to include the various species; whereas in the remaining
case we have such a common name to include the two widely separate
existing species, although we use different names to designate two
well-known fossil species. We speak of both the Indian and the African
proboscidians as elephants, although we style "mammoth" the recently
extinct hairy elephant of the north, which was more closely related to
the Asiatic elephant than the latter is to its African cousin, and
although we use the word "mastodon" to denote a more primitive type of
elephant also recently extinct in America. We have no such common term
either for the various big cats or for the various horses. Yet the
African and Asiatic elephants are far more widely separated from one
another than the lion is from the tiger, or even from the jaguar. They
are far more widely separated than horses, asses, and zebras are from
one another. As regards both the horses and the big cats which have
always preyed so largely on horses, the differences are almost
exclusively in color and in features of purely external anatomy. From
the skull and skeleton it is not possible to determine with certainty
the lion from the tiger, and both come very close to the big spotted
cats; while the skulls of the horse, the ass, and the common zebra are
with difficulty to be discriminated except by size—although the skull
of the big northernmost African zebra is totally distinct.
In consequence, when we speak of extinct horses it is often impossible
to guarantee that they were not asses or zebras; and when we speak of
the great extinct cats of Europe and North America as lions, we know
that it is possible that in life they may have looked more like tigers.
Therefore it must be understood that I use the words horse and lion as
terms of convenience and in a broad sense so as to avoid circumlocution.
I use them in exactly the way in which "elephant" is always used to
include the two totally distinct species now living in India and Africa.
By "lion" I mean any one of the big extinct cats, true cats, which in
their cranial and skeletal characters are almost or quite identical with
living lions and tigers and closely related to living jaguars. By
"horse" I mean any existing species of horse, ass, or zebra, and any
one of the numerous similar extinct species which may have belonged to
any one of these three types, or have been intermediate between any two
of them, or perhaps have been somewhat different from all of them. As
thus used, the words horse, lion, and elephant are scientifically of
nearly equivalent value.
The only region in which these three animals were not found during
Pleistocene times was Australia, which was given over wholly to a
relatively insignificant and undeveloped fauna of marsupials and into
which it is probable that man did not intrude until at a late period.
Everywhere else, from Patagonia to the Cape of Good Hope, including
regions now faunistically as utterly unlike as Peru, California, Alaska,
Siberia, Asia Minor, France, and Algiers, they abounded, many different
and peculiar species being found. The Pleistocene gradually became part
of the Age of Man; but at first it was emphatically the Age of the
Horse, the Lion, and the Elephant, and the two ages overlapped for a
very long period. The lion was primitive man's most deadly foe, as to
this day is the case in parts of Africa. He feared the lion, and avoided
him, and warred upon him, until gradually he got a little the upper
hand of him. The elephant greatly impressed the imagination of this
primitive man, and it still greatly impresses it; as will be seen by any
one who studies the carvings and pictures of our ancestors of the
glacial and postglacial epochs, or who at the present day listens to the
talk of his black gun-bearers round an African camp-fire. The horse was
and is a quarry as eagerly followed by primitive man as by the lion
himself. Ages elapsed before the horse, and finally even "my lord the
elephant" were tamed by man, as man developed something that could
properly be called a culture. The savages who, when England was merely a
peninsula of continental Europe, dwelt by the banks of the mighty rivers
which have since shrunk into the present Rhine and Seine, looked on the
mammoth and the coarse-headed wild horse of their day as furnishing the
flesh their stomachs craved, precisely as the savages of the Nile and
the Zambesi now look on the African elephant and the zebra.
This Age of Primitive Man, this Age of the Horse, the Lion, and the
Elephant, like all other historical or geological "ages," lasted longer
in some places than in others, and, instead of having sharply defined
limits, merged gradually into the preceding and succeeding ages.
Moreover—in exact analogy with other divisions of time, all of which,
however useful, are essentially artificial—we must constantly remember
that the perspective changes utterly with the point of view. All
paleontological terms of time are necessarily terms chiefly of
convenience, which have and express a real intrinsic value, but which
cannot be sharply defined. Miocene, Pliocene, Pleistocene, and Recent
are such terms. They are arbitrarily chosen bits of terminology to
express successive stages of the world's growth, and therefore
successive and varying faunas. They are not equivalent in time to one
another; the more remote the age from our own the greater is the length
of time we include therein. "Recent" denotes a short period of time
compared to "Pleistocene," and "Pleistocene" a short period compared to
"Pliocene." If there are on this earth intelligent beings at a time in
the future as remote from our day as our day is from the Pliocene, they
will certainly consider "Recent" and "Pleistocene" as one short period.
All the beast faunas and all the human cultures from the eras of the
chinless Heidelberg and Piltdown men to our own time will seem in that
remote perspective practically contemporaneous. Similarly, when we try
to grasp life as lived even in such, geologically, near-by time as any
portion of the Pleistocene, we cannot be sure of the exact
time-parallelism of closely related faunas in different parts of the
world, nor can we, in many cases, tell whether certain species were
really contemporaneous or whether they were successive. Of the general
paleontological facts, of the general aspects of the various faunas in
various parts of the world, during some roughly indicated period of
geologic time, we may be reasonably sure. But when we speak with more
minuteness, we speak doubtfully, and at any moment new discoveries may
unsettle theories by upsetting what we have supposed to be facts.
In considering what is in this chapter set forth these conditions must
be kept in mind. When I speak of what I have myself seen or of the
tools, carvings, and skeletons dug from the ground by competent
observers, I speak of facts; but as yet the explanations of these facts
must be accepted only as hypotheses, at least in part. Just as the
elephant, wild horse, and lion exist in Africa to-day, and have
disappeared from Europe and the two Americas thousands or tens of
thousands of years ago, so it may well be that they had died out in
North America ages before they had disappeared from the other end of
the western hemisphere. Again, in North America, it is as yet quite
impossible to be sure as to the exact succession, or contemporaneity of
all of the many extinct species of horse and elephant. It is with our
present knowledge equally impossible to be sure of the exact time
relations between any given North American fauna and the Eurasiatic
fauna most closely resembling it. Moreover, as yet we have only the
vaguest idea of the duration of even modern geologic time; good
observers vary as to whether a given period covers hundreds of thousands
or only tens of thousands of years.
This does not impair the value of the general picture which we can make
in our minds. It is not essentially different from what is the case in
history. If we speak of the Græco-Roman world from the days of Aristides
to those of Marcus Aurelius, we outline a historical period which has a
real unity, and of which all the parts are bound together by real ties
and real resemblances. Nevertheless, there were sharp differences in the
successive cultures of this period; even the two centuries which
intervened, say, between Miltiades and Demetrius Poliorketes, or between
Marius and Trajan, showed such differences. Dealing roughly with the
period as a whole, it would not be necessary to try to draw all the
distinctions and make all the qualifications that would be essential to
minutely accurate treatment; such treatment would merely mar the
outlines of a general sketch. The same thing is, of course, true of an
outline sketch of what our present knowledge shows of man's most
wide-spread beast associates, when he had begun, in forms not very
different from those of the lower savages to-day, to spread over the
world's surface.
Therefore it is necessary to remember that in dealing even with such a
recent chapter of paleontological discovery as that concerned with early
man and the great four-footed creatures that were his contemporaries,
our general picture can rarely pretend to more than general accuracy. It
is only in prehistoric and protohistoric Europe that the early career of
"homo sapiens" and his immediate predecessors has been worked out in
sufficient detail to give even the roughest idea of its successive
stages, and of the varying groups of great beasts with which at the
different stages man was associated. This is because the record has been
better preserved, and more closely studied in Europe than elsewhere; for
it seems fairly certain that it is in Eurasia, in the palæarctic realm,
that there took place the development of the more or less ape-like
predecessors of man and then of man himself. It is in Eurasia that all
of the remains of man's immediate predecessors have been found—from the
Javan pithecanthropus which can only doubtfully be called human, to the
Piltdown and Heidelberg men, who were undoubtedly human, but who were so
much closer than any existing savage to the beasts that (unless our
present imperfect knowledge proves erroneous) they can hardly be deemed
specifically identical with modern homo sapiens. Even the more modern
Neanderthal men are probably not ancestral to our own stock. It is in
Europe, following on these predecessors of existing man, that we find
the skeletons, the weapons and tools, and the carvings of existing man
in his earliest stages; and mingled with his remains those of the
strange and mighty beasts which dwelt beside him in the land. Probably
these European forefathers of existing man came from a stock which had
previously gone through its early human and prehuman stages in Asia. But
we only know what happened in Europe. There was a slow, halting, and
interrupted but on the whole steady development in physical
type—sometimes the type itself gradually changing, while sometimes it
was displaced by a wholly different type of wholly different blood.
Roughly parallel with this was a corresponding development in cultural
type. Probably from the earliest times, and certainly in late times,
development or change in physical type was often wholly unrelated to
development or change in culture. Sometimes the cultural change was an
autochthonous development. Sometimes it was due to a more or less
complete change in blood, owing to the immigration of a strong alien
type of humanity. Sometimes it was due to the adoption of an alien
culture.
Many good observers nowadays, judging from the facts at present
accessible, are inclined to think that the American Indian stocks were
the first human stocks that peopled the western hemisphere, that they
are by blood nearest of kin to certain race-elements still existing in
northeastern Asia—representing the only inhabitants of northeastern
Asia when man first penetrated from there to northwestern America—and
that more remotely they may be kin to certain late Palæolithic men of
Europe. But much of the American Indian culture was essentially a
Neolithic culture, seemingly from the beginning. In places—Peru,
Maya-land, the Mexican plateau—it at times developed into a
civilization equally extraordinary for its achievements and for its
shortcomings and evanescence; but it never developed a metal epoch
corresponding to, say, the bronze age of the Mediterranean, and although
the small camel, the llama, was tamed in South America, in North
America, the ox, sheep, white goat, and reindeer were never made
servants of man, as befell so many corresponding beasts of Eurasia.
In this last respect the American Indians stayed almost on the level of
the African tribes, whose native civilization was otherwise far less
advanced. The African buffalo is as readily tamed as its Asiatic
brother; the zebra was as susceptible of taming as the early wild horse
and ass; the eland is probably of all big ruminants the one that most
readily lends itself to domestication. But none of them was tamed until
tribes owning animals which had been tamed for ages appeared in Africa;
and then the already-tamed animals were accepted in their stead. The
asses, cattle, sheep, and goats of Asia are now the domestic animals of
the negroes and of the whites in Africa, merely because it is easier,
more profitable, and more convenient to deal with animals already
accustomed for ages to the yoke of domestic servitude than to again go
through the labor incident to changing a wild into a tame beast.
It is probable that during the immense stretch of time which in Europe
covered the growth of the various successive Palæolithic, and finally
Neolithic, cultures—the "old-stone" ages during which man used stone
implements which he merely chipped and flaked, and the "new-stone" age
in which he ground and polished them—there happened time and again what
has happened in the history and prehistory of man in Africa and North
America. One of the incidents in this parallelism is the way in which
the inhabitants accepted animals already trained and brought from
elsewhere rather than attempt to train the similar beasts of their own
forests. Doubtless the reason why the European bison is not a domestic
animal is exactly the same as the reason why the American bison and
African buffalo are not domestic animals. The northern European hunting
savages were displaced or subjugated by, or received a higher culture
from, tribes bringing from Asia or from the Mediterranean lands the
cattle they had already tamed. The same things happened, in Africa south
of the Sahara while it was still shrouded from civilized vision, and in
America since the coming of the European.
These hunting savages existed for ages, for hundreds of thousands of
years, in Europe. During this period of time—immense by historic
standards, yet geologically a mere moment—many different human types
succeeded one another. The climate swung to and from glacial to
subtropical; fauna succeeded fauna. One group of species of big beasts
succeeded another as the climate and plant life changed; and then itself
gave place to a third; and perhaps once more resumed its ancient place
as the physical conditions again became what they once had been. At
certain periods the musk-ox, the reindeer, the woolly rhinoceros, and
the hairy mammoth, together with huge cave-bears, were found; at other
periods southern forms of elephant and rhinoceros, and such tropical
creatures as the hippopotamus, replaced the beasts of the snow land.
Horses of different species were sometimes present in incredible
numbers. There were species of wild cattle, including the European
bison, and the urus or aurochs—spoken of by Cæsar, and kin to, and
doubtless partly ancestral to, the tame ox. The cave-lion, perhaps
indistinguishable from the modern African lion, was the most formidable
beast of prey. I say "perhaps" indistinguishable, for we cannot be quite
certain. Some of the races of cave-dwelling men were good artists, and
carved spirited figures of mammoth, rhinoceros, bison, horse, reindeer,
and bear on ivory, or on the walls of caves. The big lion-like cats
appear only rarely in these pictures.
In most cases the arctic and warm-temperate or near-tropical animals
supplanted one another only incompletely as the waves of life advanced
and receded when the climate changed. This seems a rather puzzling
conjunction. The explanation is twofold. When the climate changes, when
it becomes warmer, for instance, northern creatures that once were at
home in the lowlands draw off into the neighboring highlands, leaving
their old haunts to newcomers from the south, while nevertheless the two
faunas may be only a few miles apart; just as in Montana and Alberta
moose and caribou in certain places were found side by side with the
prongbuck. Moreover, some species possess an adaptability which their
close kin do not, and can thrive under widely different temperature
conditions. A century ago the hippopotamus was found in the temperate
Cape Colony, close to mountain ranges climatically fit for the typical
beasts of north-temperate Eurasia. In Arizona at the present day mammals
and birds of the Canadian fauna live on the mountain tops around the
bases of which flourish animals characteristic of the tropical Mexican
plateau; the former having been left stranded on high mountain islands
when, with the retreat of the glaciers, the climate of the United States
grew warmer and the tide of southern life-forms swept northward over the
lowlands. Under such conditions the same river deposits might show a
combination of utterly different faunas. Moreover, some modern animals
are found from the arctics to the tropics. The American lynx extends, in
closely connected forms, from the torrid deserts of Mexico to arctic
Alaska; so does the mountain-sheep. The tiger flourishes in the steaming
Malay forests and in snowy Manchuria. I have found the cougar breeding
in the frozen, bitter midwinter among the high Rockies, in a country
where snow covered the ground for six months, and where the caribou
would be entirely at home; and again in Brazil under the equator, in the
atmosphere of a hot-house. There were periods, during the ages before
history dawned, but when man had long dwelt in Europe, in which herds of
reindeer may have roamed the French and English uplands within sight of
rivers wherein the hippopotamus dwelt as comfortably as he recently did
at the Cape of Good Hope.
Some of the more recent of these European hunting savages—those who
were perhaps in part our own forefathers, or who perhaps were of
substantially the same ethnic type as the men of the older race strains
in northeastern Asia, and even possibly of the American Indians—and
many of their more remote predecessors were contemporaries of the lion,
the horse, and the elephant. Different species of horse and elephant
succeeded one another. The earlier ones were contemporaries of the
hippopotamus and of not only the lion but the sabretooth. When the hairy
elephant, the mammoth, was present, the fauna also often included the
cave-lion, cave-hyena, cave-bear, wolf, boar, woolly rhinoceros, many
species of deer (including the moose and that huge fallow deer, the
Irish elk), horses, and the bison and the aurochs. The mammoth and
woolly rhinoceros died out so recently that their carcasses are
discovered preserved in the Siberian ice, and the undigested food in
their stomachs shows that they ate northern plants of the kinds now
common, and the twigs of the conifers and other trees which still
flourish in the boreal realm of both hemispheres.
The lion was doubtless the most dreaded foe of the ancient European,
just as he is to this day of certain African tribes. The Palæolithic
hunters slaughtered myriads of wild horses, just as the ebony-hued
hunters of Africa now slaughter the zebra and feast on its oily flesh.
The spirited carvings and sketches of the hairy mammoth by the later
Palæolithic cave-dwellers show that the elephant of the cold northlands
had impressed their imaginations precisely as the hairless elephant of
the hot south now impresses the imaginations of the tribes that dwell
under the vertical African sun. The rhinoceros and wild cattle of the
pine forests played in their lives the part played in the lives of our
contemporaries, the hunting tribes of Africa, by the rhinoceros and the
buffalo—the African wild ox—which dwell among open forests of acacias
and drink from palm-bordered rivers. They saw no animal like that
strange creature, the African giraffe; and several kinds of deer took
the place of the varied species of bovine ruminants which, in popular
parlance, we group together as antelopes.
Substantially the fauna of mighty beasts which furnished the means of
livelihood, and also constantly offered the menace of death, to our
European forefathers—or to the predecessors of our forefathers—was
like that magnificent fauna which we who have travelled among the
savages of present-day Africa count it one of our greatest pleasures to
have seen. During the ages when the successive races of hunter-savages
dwelt in Europe a similar magnificent fauna of huge and strange beasts
flourished on all the continents of the globe except in Australia. In
Europe it vanished in prehistoric times, when man had long dwelt in the
land. In Africa south of the Sahara, and partially in spots of Asia, it
has persisted to this day. In North America it died out before, or
perhaps, as regards the last stragglers, immediately after, the coming
of man; in South America it seems clear that it survived, at least in
places, until he was well established.
The three abundant and conspicuous beasts, all three typical of the
great mammalian fauna which was contemporary with the prehistoric human
hunters, and all three common to all the continents on which this great
mammalian fauna was found, were the lion—using the name to cover
several species of huge horse-killing and man-killing cats; the
elephant, including several totally different species, among them the
mammoth and mastodon; and the horse, including numerous widely different
species. Together with these three universally distributed animals were
many others belonging to types confined to certain of the continents.
Rhinoceros were found in Europe, Asia, and Africa (they had once
flourished in North America but had died out long before man appeared on
the globe). Camels were found in Asia, in South America, and especially
in North America, which was their centre of abundance and the place
where they had developed. Wild oxen were found in all the continents
except South America; deer everywhere except in true Africa,
zoogeographical Africa, Africa south of the Sahara. The pigs of the Old
World were replaced by the entirely different peccaries of the New
World. Sheep, goats, and goat-antelopes lived in Eurasia and North
America. Most of the groups of big ruminants commonly called "antelopes"
are now confined to Africa; but it appears that formerly various
representatives of them reached America. The giraffe through this period
was purely African; the hippopotamus has retreated to Africa, although
in the period we are considering its range extended to Eurasia. In South
America were many extraordinary creatures totally different from one
another, including ground-sloths as big as elephants. Two or three
outlying representatives of the ground-sloths had wandered into North
America; but elsewhere there were no animals in any way resembling
them. The horse, the lion, and the elephant were the three striking
representatives of this vast and varied fauna which were common to all
five continents.
The North American fauna of this type reached its height about the
time—extending over many scores of thousands of years—when successive
ice ages alternated with long stretches of temperate or subtropical
climate throughout the northern hemisphere. During the period when this
great North American fauna flourished hunter-savages of archaic type
lived amid, and partly on, the great game of Europe. But, as far as we
know, men did not come to America until after, or at the very end of,
the time when these huge grass-eaters and twig-eaters, and the huge
flesh-eaters which preyed on them, vanished from the earth, owing to
causes which in most cases we cannot as yet even guess.
Much the most striking and interesting collection of the remains of this
wonderful fauna is to be found near one of our big cities. On the
outskirts of Los Angeles, in southern California, are asphalt deposits
springing from petroleum beds in the shales below. The oil seeping up to
the surface has formed shallow, spread-out pools and, occasionally, deep
pits covered with water. In part of the area these pits and pools of
tar have existed for scores of thousands or hundreds of thousands of
years, since far back in the Pleistocene. They then acted as very
dangerous and efficient mammal traps and bird traps—and now continue so
to act, for the small mammals and the birds of the neighborhood still
wander into them, get caught in the sticky substance, and die, as I have
myself seen. Moreover the tar serves as a preservative of the bones of
the creatures that thus perish. In consequence some of the ancient pits
and pools are filled with immense masses of the well-preserved bones of
the strange creatures that were smothered in them ages ago.
Nowhere else is there any such assemblage of remains giving such a
nearly complete picture of the fauna of a given region at a given time.
A striking peculiarity is that the skeletons of the flesh-eaters far
surpass in number the skeletons of the plant-eaters. This is something
almost unique, for of course predatory animals are of necessity much
less numerous than the animals on which they prey. The reversal in this
case of the usual proportions between the skeletal remains of
herbivorous and carnivorous beasts and birds is due to the character of
the deposits. The tar round the edges of the pools or pits hardens,
becomes covered with dust, and looks like solid earth; and water often
stands in the tar pits after rain, while at night the shallow pools of
fresh tar look like water. Evidently the big grazing or browsing beasts
now and then wandered out on the hard asphalt next the solid ground, and
suddenly became mired in the soft tar beyond. Probably the pits in which
water stood served as traps year after year as the thirsty herds sought
drink. Then each dead or dying animal became itself a lure for all kinds
of flesh-eating beasts and birds, which in their turn were entrapped in
the sticky mass. In similar manner, thirty years ago on the Little
Missouri, I have known a grizzly bear, a couple of timber-wolves, and
several coyotes to be attracted to the carcass of a steer which had
bogged down in the springtime beside an alkali pool.
Another result of the peculiar conditions under which the skeletons
accumulated is that an unusually large number of very old, very young,
and maimed or crippled creatures were entrapped. Doubtless animals in
full vigor were more apt to work themselves free at the moment when they
found they were caught in the tar; and, moreover, a wolf or sabretooth
which was weakened by age or by wounds received in encounter with its
rivals, or with some formidable quarry, and which therefore found its
usual prey difficult to catch, would be apt to hang around places where
carcasses, or living creatures still feebly struggling, offered
themselves to ravenous appetites.
The plant remains in these deposits show that the climate and vegetation
were substantially those of California to-day, although in some respects
indicating northern rather than southern California. There were
cypress-trees of a kind still common farther north, manzanita, juniper,
and oaks. Evidently the region was one of open, grassy plains varied
with timber belts and groves. It has been said that to support such a
fauna the vegetation must have been much more luxuriant than in this
region at present. This is probably an error. The great game regions of
Africa are those of scanty vegetation. Thick forest holds far less big
animal life. Crossing the sunny Athi or Kapiti plains of East Africa,
where the few trees are thorny, stunted acacias and the low grass is
brown and brittle under the drought, the herds of zebra, hartebeest,
wildebeest, and gazelle are a perpetual delight and wonder; and
elephant, rhinoceros, and buffalo abounded on them in the days before
the white man came. On the Guaso Nyero of the north, and in the Sotik,
the country was even drier at the time of my visit, and the character of
the vegetation showed how light the normal rainfall was. The land was
open, grassy plain, or was thinly covered with thorn scrub, with here
and there acacia groves and narrow belts of thicker timber growth along
the watercourses, and in the Sotik gnarled gray olives. Yet the game
swarmed. We watched the teeming masses come down to drink at the
shrunken rivers or at the dwindling ponds beside which our tents were
pitched. As the line of the safari walked forward under the brazen sky,
while we white men rode at the head with our rifles, the herds of
strange and beautiful wild creatures watched us, with ears pricked
forward, or stood heedless in the thin shade of the trees, their tails
switching ceaselessly at the biting flies. In wealth of numbers, in rich
variety and grandeur of species, the magnificent fauna we then saw was
not substantially inferior to that which an age before dwelt on the
California plains.
This Pleistocene California fauna included many beasts which persisted
in the land until our own day. There were cougars, lynxes,
timber-wolves, gray foxes, coyotes, bears, pronghorn antelopes and
black-tail or white-tail deer nearly, or quite, identical with the
modern forms. They were the same animals which I and my fellow ranchmen
hunted when, in the early eighties of the last century, our branded
cattle were first driven to the Little Missouri. They swarmed on the
upper Missouri and the Yellowstone when Lewis and Clark found the bison
and wapiti so tame that they would hardly move out of the way, while the
grizzly bears slept on the open plains and fearlessly attacked the
travellers. But in the Pleistocene, at the time we are considering, the
day of these modern creatures had only begun. The contents of the
tar-pits show that the animals named above were few in number, compared
to the great beasts with which they were associated.
The giant among these Pleistocene giants of California, probably the
largest mammal that ever walked the earth, was the huge imperial
elephant. This mighty beast stood at least two feet higher than the
colossal African elephant of to-day, which itself is bigger than the
mammoth, and as big as any other extinct elephant. The curved tusks of
the imperial elephant reached a length of sixteen feet. A herd of such
mighty beasts must have been an awe-inspiring sight—had there been
human eyes to see it. Nor were they the only representatives of their
family. A much more archaic type of elephant, the mastodon, flourished
beside its gigantic cousin. The mastodon was a relatively squat
creature, standing certainly four feet shorter than the imperial
elephant, with comparatively small and slightly curved tusks and a
flatter head. Enormous numbers of mastodons ranged over what is now the
United States, and the adjacent parts of Canada and Mexico. The
mastodons represented a stage farther back in the evolutionary line than
the true elephants, and in the Old World they died out completely before
the latter disappeared even from Europe and Siberia. But in North
America, for unknown reasons, they outlasted their more highly developed
kinsfolk and rivals, and there is some ground for believing that they
did not completely disappear until after the arrival of man on this
continent.
The elephant stock developed in the Old World, and it is probable that
the true elephants were geologically recent immigrants to America,
coming across the land bridge which then connected Alaska and Siberia.
In California they encountered the big descendants of other big
immigrants, which had reached North America by another temporary land
bridge, but from another continent, South America. These were the
ground-sloths, giant edentates, which reached an extraordinary
development in the southern half of our hemisphere, where distant and
diminutive relatives—tree-sloths, ant-eaters, armadillos—still live.
The most plentiful of these California ground-sloths, the mylodon, was
about the size of a rhinoceros; an unwieldy, slow-moving creature,
feeding on plants, and in appearance utterly unlike anything now living.
Together with these great beasts belonging to stocks that in recent
geologic time had immigrated hither from the Old World and from the
southern half of the New World was another huge beast of remote native
ancestry. This was a giant camel, with a neck almost like that of a
giraffe. Camels—including llamas—developed in North America. Their
evolutionary history certainly stretched through a period of two or
three million—perhaps four or five million—years on this continent,
reaching back to a little Eocene ancestor no bigger than a jack-rabbit.
Yet after living and developing in the land through these untold ages,
over a period inconceivably long to our apprehension, the camels
completely died out on this continent of their birth, although not
until they had sent branches to Asia and South America, where their
descendants still survive.
Two other grass-eating beasts, of large size—although smaller than the
above—were also plentiful. One, a bison, bigger, straighter-horned and
less specialized than our modern bison, represented the cattle, which
were among the animals that passed to America over the Alaskan land
bridge in Pleistocene time.
The other was a big, coarse-headed horse, much larger than any modern
wild horse, and kin to the then existing giant horse of Texas, which was
the size of a percheron. The horses, like the camels, had gone through
their developmental history on this continent, the earliest ancestor,
the little four-toed "dawn horse" of the Eocene, being likewise the size
of a jack-rabbit. Through millions of years, while myriads of
generations followed one another, the two families developed side by
side, increasing in size and seemingly in adaptation to the environment.
Each stock branched into many different species and genera. They spread
into the Old World and into South America. Then, suddenly,—that is,
suddenly in zoologic sense—both completely died out in their ancient
home, and the horses in South America also, whereas half a dozen very
distinct species are still found in Asia and Africa.
All these great creatures wandered in herds to and fro across the grassy
Californian plains and among the reaches of open forest. Preying upon
them were certain carnivores grimmer and more terrible than any now
existing. The most distinctive and seemingly the most plentiful was the
sabretooth. This was a huge, squat, short-tailed, heavily built cat with
upper canines which had developed to an almost walrus-like length; only,
instead of being round and blunt like walrus tusks, they were sharp,
with a thin, cutting edge, so that they really were entitled to be
called sabres or daggers. Whether the creature was colored like a lion
or like a tiger or like neither, we do not know, for it had no
connection with either save its remote kinship with all the cats. The
sabretooth cats, like the true cats, had gone through an immensely long
period of developmental history in North America, although they did not
appear here as early as the little camels and horses. Far back across
the ages, at or just after the close of the Eocene—the "dawn age" of
mammalian life—certain moderate-sized or small cat-like creatures
existed on this continent, doubtless ancestral to the sabretooth, but
so generalized in type that they display close affinities with the true
cats, and even on certain points with the primitive dog creatures of the
time. Age followed age—Oligocene, Miocene, Pliocene. The continents
rose and sank and were connected and disconnected. Vast lakes appeared
and disappeared. Mountain chains wore down and other mountain chains
were thrust upward. Periods of heat, during which rich forests
flourished north of the arctic circle, were followed by periods of cold,
when the glacial ice-cap crept down half-way across the present
temperate zone. Slowly, slowly, while the surface of the world thus
changed, and through innumerable reaches of time, the sabretooth cats
and true cats developed along many different lines in both the Old World
and the New. One form of sabretooth was in Europe with the bestial
near-human things who were the immediate predecessors of the first low
but entirely human savages. It was in the two Americas, however, that
the sabretooth line culminated, immediately before its final extinction,
in its largest and most formidable forms. This California sabretooth was
not taller than a big cougar or leopard, but was probably as heavy as a
fair-sized lion. Its skeletal build is such that it cannot have been an
agile creature, apt at the pursuit of light and swift prey. By rugged
strength and by the development of its terrible stabbing and cutting
dagger teeth, that is, by sheer fighting ability, it was fitted for
attack upon and battle with the massive herbivores then so plentiful. It
must indeed have been a fearsome beast in close grapple. Doubtless with
its sharp, retractile claws it hung onto the huge bodies of elephant,
camel, and ground-sloth, of horse and bison, while the sabres were
driven again and again into the mortal parts of the prey and slashed the
flesh as they withdrew. It seems possible that the mouth was opened wide
and stabbing blows delivered, almost as a rattlesnake strikes with
raised fangs. Vast numbers of sabretooth skeletons have been found in
the asphalt; evidently the strange, formidable creature haunted any
region which held attraction for the various kinds of heavy game on
which it preyed.
The only other carnivore as abundant as the sabretooth was a giant wolf.
This was heavier than any existing wolf, with head and teeth still
larger in proportion. The legs were comparatively light. Evidently, like
the sabretooth, this giant wolf had become specialized as a beast of
battle, fitted to attack and master the bulky browsers and grazers, but
not to overtake those that were smaller and swifter. The massive jaws
and teeth could smash heavy bones and tear the toughest hide; and a
hungry pack of these monsters, able to assail in open fight any quarry
no matter how fierce or powerful, must have spread dire havoc and dismay
among all things that could not escape by flight.
There were two still larger predatory species, which were much less
plentiful than either the wolf or the sabretooth. One was a short-faced
cave-bear, far larger than even the huge Alaskan bear of to-day.
Doubtless it took toll of the herds; but bears are omnivorous beasts,
and not purely predatory in the sense that is true of those finished
killers, the wolves and big cats. Unlike the wolves and cats, bears were
geologically recent immigrants to America.
The other was a true cat, a mighty beast; bigger than the African lion
of to-day; indeed, perhaps the biggest and most powerful lion-like or
tiger-like cat that ever existed. Seemingly it was much rarer than the
sabretooth; but it is possible that this seeming rarity was due to its
not lurking in the neighborhood of pools and licks but travelling more
freely over the wastes, being of a build fit not only for combat but for
an active and wandering life. It is usually spoken of as kin to the
African lion, a decidedly smaller beast. It is possible that its real
kinship lies with the tiger. The Manchurian form of the tiger is an
enormous beast, and a careful comparison of the skulls and skeletons may
show that it equals in size the huge western American cat of Pleistocene
times. I have already spoken of the fact that in many cases it is almost
impossible to distinguish the lion and tiger apart by the bones alone;
and it may be that the exact affinities of these recently extinct
species with living forms cannot be definitely determined. But during
historic and prehistoric times the lion has been a beast of western
Eurasia and of Africa. The tiger, on the contrary, is and has been a
beast of eastern Asia, and apparently has been spreading westward and
perhaps southward—that it was not as ancient an inhabitant of
jungle-covered southern India as the elephant and leopard seems probable
from the fact that it is not found in Ceylon, which island in all
likelihood preserves most of the southern Indian fauna that existed
prior to its separation from the mainland. Moreover, the finest form of
tiger exists in cold northeastern Asia. In Pleistocene times this
portion of Asia was connected by a broad land bridge with western
America, where the mighty American cat then roved and preyed on the
herds of huge plant-eating beasts. We know that many Asiatic beasts
crossed over this land bridge—the bears, bison, mountain-sheep, moose,
caribou, and wapiti, which still live both in Asia and North America,
and the mammoth and cave-bears, which have died out on both continents.
It is at least possible—further investigation may or may not show it to
be more than possible—that the huge Pleistocene cat of western America
was the collateral ancestor of the Manchurian tiger. Whether it was
another immigrant from Asia, or a developed form of some big American
Pliocene cat, cannot with our present knowledge be determined.
Surely the thought of this vast and teeming, and utterly vanished wild
life, must strongly appeal to every man of knowledge and love of nature,
who is gifted with the imaginative power to visualize the past and to
feel the keen delight known only to those who care intensely both for
thought and for action, both for the rich experience acquired by toil
and adventure, and for the rich experience obtained through books
recording the studies of others.
Doubtless such capacity of imaginative appreciation is of no practical
help to the hunter of big game to-day, any more than the power to
visualize the long-vanished past in history helps a practical
politician
to do his ordinary work in the present workaday world. The governor of
Gibraltar or of Aden, who cares merely to do his own intensely practical
work, need know nothing whatever about any history more ancient than
that of the last generation. But this is not true of the traveller. It
is not even true of the politician who wishes to get full enjoyment out
of life without shirking its duties. He certainly must not become a mere
dreamer, or believe that his dreams will help him in practical action.
But joy, just for joy's sake, has its place too, and need in no way
interfere with work; and, of course, this is as true of the joy of the
mind as of the joy of the body. As a man steams into the Mediterranean
between the African coast and the "purple, painted headlands" of Spain,
it is well for him if he can bring before his vision the galleys of the
Greek and Carthaginian mercantile adventurers, and of the conquering
Romans; the boats of the wolf-hearted Arabs; the long "snakes" of the
Norse pirates, Odin's darlings; the stately and gorgeous war craft of
Don John, the square-sailed ships of the fighting Dutch admirals, and
the lofty three-deckers of Nelson, the greatest of all the masters of
the sea. Aden is like a furnace between the hot sea and the hot sand;
but at the sight of the old rock cisterns, carved by forgotten hands,
one realizes why on that coast of barren desolation every maritime
people in turn, from the mists that shroud an immemorial antiquity to
our own day of fevered materialistic civilization, has seized Aden
Bay—Egyptian, Sabean, Byzantine, Turk, Persian, Portuguese, Englishman;
and always, a few miles distant, in the thirsty sands, the changeless
desert folk have waited until pride spent itself and failed, and the new
power passed, as each old power had passed, and then the merciless men
of the waste once more claimed their own.
Gibraltar and Aden cannot mean to the unimaginative what they mean to
the men of vision, to the men stirred by the hero tales of the past, by
the dim records of half-forgotten peoples. These men may or may not do
their work as well as others, but their gifts count in the joy of
living. Enjoyment the same in kind comes to the man who can clothe with
flesh the dry bones of bygone ages, and can see before his eyes the
great beasts, hunters and hunted, the beasts so long dead, which
thronged the Californian land at a time when in all its physical
features it had already become essentially what it still continues to
be.
The beast life of this prehistoric California must be called ancient by
a standard which would adjudge the Egyptian pyramids and the
Mesopotamian palace mounds and the Maya forest temples to be modern. Yet
when expressed in geologic terms it was but of yesterday. When it
flourished the Eurasian hunting savages were in substantially the same
stage of progress as the African hunting savages who now live surrounded
by a similar fauna. On the whole, taking into account the number,
variety, and size of the great beasts, the fauna which surrounded
Palæolithic man in Europe was inferior to that amid which dwell the
black-skinned savages of equatorial Africa. Even Africa, however,
although unmatched in its wealth of antelopes, cannot quite parallel,
with its lion, elephant, and zebras, the lordlier elephant, the great
horse, and the huge cat of the earlier Californian fauna; and the
giraffe, the hyena, the rhinoceros, and the hippopotamus do not quite
offset the sabretooth, the giant wolf, the mastodon, the various species
of enormous ground-sloths, and the huge camel; the bison and buffalo
about balance each other.
There were no human eyes to see nor human ears to hear what went on in
southern California when it held an animal life as fierce and strange
and formidable as mid-Africa to-day. The towering imperial elephants and
the burly mastodons trumpeted their approach one to the other. The great
camels, striding noiselessly on their padded feet, passed the clumsy
ground-sloths on their way to water. The herds of huge horses and bison
drank together in pools where the edges were trodden into mire by
innumerable hoofs. All these creatures grew alertly on guard when the
shadows lengthened and the long-drawn baying of the wolf pack heralded
the night of slaughter and of fear; and the dusk thrilled with the
ominous questing yawns of sabretooth and giant tiger, as the beasts of
havoc prowled abroad from their day lairs among the manzanitas, or under
cypress and live-oak.
The tar-pools caught birds as well as beasts. Most of these birds were
modern—vultures, eagles, geese, herons. But there were condor-like
birds twice the size of any living condor, the biggest birds, so far as
we know, that ever flew. There were also, instead of wild turkeys, great
quantities of wild peacocks—at least they have been identified as
peacocks or similar big, pheasant-like birds. If the identification is
correct, this is an unexpected discovery and a fresh proof of how this
extinct American fauna at so many points resembled that of Asia. It was
natural that a collateral ancestor of the present Asiatic pheasant-like
birds should dwell beside a collateral ancestor of the present Asiatic
tiger.[1]
Moreover, the tar-pools hold human bones. These, however, are probably
of much later date than the magnificent fauna above described, perhaps
only a few thousand years old. They belong to a rather advanced type of
man. It is probable that before man came to America at all, the earlier
types had died out in Eurasia, or had been absorbed and developed, or
else had been thrust southward into Africa, Tasmania, Australia, and
remote forest tracts of Indo-Malaysia, where, being such backward
savages, they never developed anything remotely resembling a
civilization. It was probably people kin to some of the later
cave-dwellers who furnished the first (and perhaps until the advent of
the white man the only important) immigration to America. These
immigrants, the ancestors of all the tribes of Indians, spread from
Alaska to Tierra del Fuego. Over most of the territory in both Americas
they remained at the hunting stage of savage life, although they
generally supplemented their hunting by a certain amount of cultivation
of the soil, and although in places they developed into advanced and
very peculiar culture communities.
When these savages reached North America it is likely, from our present
knowledge, that the terrible and magnificent Pleistocene fauna had
vanished, although in places the last survivors of the mastodon, and
perhaps of one or two other forms, may still have lingered. What were
the causes of this wide-spread, and complete, and—geologically
speaking—sudden extermination of so many and so varied types of great
herbivorous creatures, we cannot say. It may be we can never do more
than guess at them. It is certainly an extraordinary thing that complete
destruction should have suddenly fallen on all, literally all, of the
species. Camels and horses, after they had dwelt on this continent for
millions of years, since almost the dawn of mammalian life, developing
from little beasts the size of woodchucks into the largest and most
stately creatures of their kind that ever trod the earth's surface, all
at once disappeared to the very last individual. Ground-sloths and
elephants vanished likewise. The bigger forms of bison also died out,
although one species remained. Many causes of extinction have been
suggested. Perhaps all of them were more or less operative. Perhaps
others of which we know nothing were operative. We cannot say.
But as regards certain of the formidable, but heavy rather than active,
beasts of prey it is possible to hazard a guess. Compared to agile
destroyers like the cougar and the timber-wolf, the sabretooth and the
big-headed, small-legged giant wolf were strong, heavy, rather clumsy
creatures. Predatory animals of their kind were beasts of battle rather
than beasts of the chase. They were fitted to overcome by downright
fighting strength a big, slow, self-confident quarry, rather than to run
down a swift and timid quarry by speed or creep up to a wary and timid
quarry by sinuous stealth. So long as the heavy herbivores were the most
numerous these fighting carnivores were dominant over their sly, swift,
slinking brethren. But when the great mass of plant-eaters grew to
trust to speed and vigilance for their safety there was no longer room
for preying beasts of mere prowess.
In South America it is probable that the heavy fauna died out much later
than in North America and northern Eurasia; that is, it died out much
later than in what zoogeographers call the holarctic realm. During most
of the Tertiary period or age of mammals, the period intervening between
the close of the age of great reptiles and the time when man in human
form appeared on the planet, South America was an island, and its faunal
history was as distinct and peculiar as that of Australia. Aside from
marsupials and New World monkeys, its most characteristic animals were
edentates and very queer ungulates with no resemblance to those of any
other continent. Toward the close of the Tertiary land bridges connected
the two Americas, and an interchange of faunas followed. The South
American fauna was immensely enriched by the incoming of elephants,
horses, sabretooth cats, true cats, camels, bears, tapirs, peccaries,
deer, and dogs, all of which developed along new and individual lines. A
few of these species, llamas and tapirs for instance, still persist in
South America although they have died out in the land from which they
came. But in the end, and also for unknown causes, this great fauna
died out in South America likewise, leaving a continent faunistically
even more impoverished than North America. The great autochthonous forms
shared the extinction of the big creatures of the immigrant fauna; for
under stress of competition with the newcomers, the ancient ungulates
and edentates had developed giants of their own.
Recent discoveries have shown that the extinction was not complete when
the ancestors of the Indians of to-day reached the southern Andes and
the Argentine plains. An age previously the forefathers of these
newcomers had lived in a land with the wild horse, the wild elephant,
and the lion; and now, at the opposite end of the world, they had
themselves reached such a land. The elephants were mastodons of peculiar
type; the horses were of several kinds, some resembling modern horses,
others differing from them in leg and skull formation more than any of
the existing species of ass, horse, or zebra differ from one another;
the huge cats probably resembled some other big modern feline more than
they did the lion. Associated with them were many great beasts, whose
like does not now exist on earth. The sabretooth was there, as
formidable as his brother of the north, and, like this brother, bigger
and more specialized than any of his Old World kin, which were probably
already extinct. Among the ungulates of native origin was the
long-necked, high-standing macrauchenia, shaped something like a huge,
humpless camel or giraffe, and with a short proboscis. This animal
doubtless browsed among the trees. Another native ungulate, the toxodon,
as big and heavily made as a rhinoceros, was probably amphibious, and
had teeth superficially resembling those of a rodent. The edentates not
only included various ground-sloths, among them the megatherium, which
was the size of an elephant, and the somewhat smaller mylodon, but also
creatures as fantastic as those of a nightmare. These were the
glyptodons, which were bulkier than oxen and were clad in defensive
plate-armor more complete than that of an armadillo; in one species the
long, armored tail terminated in a huge spiked knob, like that of some
forms of mediæval mace.
The glyptodons doubtless trusted for protection to their mailed coats.
The ground-sloths had no armor. Like the terrestrial ant-bear of Brazil
they walked slowly on the outer edges of their fore feet, which were
armed with long and powerful digging claws. They could neither flee nor
hide; and it seems a marvel that they could have held their own in the
land against the big cats and sabretooth. Yet they persisted for ages,
and spread northward from South America. It is hard to account for this.
But it is just as hard to account for certain phenomena that are
occurring before our very eyes. While journeying through the interior of
Brazil I not infrequently came across the big tamandua, the ant-bear or
ant-eater. We found it not only in the forests but out on the marshes
and prairies. It is almost as big as a small black bear. In its native
haunts it is very conspicuous, both because of its size and its
coloration, and as it never attempts to hide it is always easily seen.
It is so slow that a man can run it down on foot. It has no teeth, and
its long, curved snout gives its small head an almost bird-like look.
Its fore paws, armed with long, digging claws, are turned in, and it
walks on their sides. It is long-haired and thick-hided, colored black
and white, and with a long, bushy tail held aloft; and as it retreats at
a wabbly canter, its brush shaking above its back, it looks anything but
formidable. Yet it is a gallant fighter, and can inflict severe wounds
with its claws, as well as hugging with its powerful fore legs; and if
menaced it will itself fearlessly assail man or dog. When chased by
hounds, in the open, I have seen one instantly throw itself on its back,
in which position it was much more dangerous to the hounds than they
were to it. Doubtless if attacked by a jaguar—and we killed jaguars in
the immediate neighborhood—it would, if given a moment's warning, have
defended itself in the same fashion. I suppose that this defense would
be successful; for otherwise it seems incredible that such a
conspicuous, slow-moving beast can exist at all in exactly the places
where jaguars, able to kill a cow or horse, are plentiful. But, even so,
it is difficult to understand how it has been able to persist for ages
in company with the great spotted cat, the tyrant of the Brazilian
wilderness. At any rate, with this example before us, we need not wonder
overmuch at the ability of megatherium and mylodon to hold their own in
the presence of the sabretooth.
In the late fall of 1913, as previously described, I motored north from
the beautiful Andean lake, Nahuel Huapi, through the stony Patagonian
plains to the Rio Negro. The only wild things of any size that we saw
were the rheas, or South American ostriches, and a couple of guanacos,
or wild llamas, small, swift, humpless camels, of which the ancestral
forms were abundant in the North American Miocene. But one of my
companions, the distinguished Argentine explorer, educator, and man of
science, Francisco Moreno, had some years previously made a discovery
which showed that not many thousand years back, when the Indians had
already come into the land, the huge and varied fauna of the Pleistocene
still lingered at the foot of the Andes. He had found a cave in which
savage men had dwelt; and in the cave were the remains of the animals
which they had killed, or which had entered the cave at times when its
human tenants were absent. Besides the weapons and utensils of the
savages, he had found the grass which they had used for beds, and
enclosures walled with stones for purposes of which he could not be
sure. It will be remembered that in the cave-home of the 'Ndorobo which
Kermit found there were beds of grass, and enclosures walled with brush,
in which their dogs were kept. Whether these early Patagonian Indians
had dogs I do not know; but many African tribes build low stone walls as
foundations for sheds used for different purposes; and sometimes, among
savages, it is absolutely impossible to guess the use to which a given
structure is put unless it is actually seen in use—exactly as
sometimes it is wholly impossible to divine what a particular specimen
of savage pictorial art indicates unless the savage is there to explain
it to his civilized brother.
Among the signs of human occupation Doctor Moreno found, well preserved
in the cold cave, not only the almost fresh bones, but even pieces of
the skin, of certain extinct animals. Among the species whose bones were
found were the macrauchenia, tiger, horse, and mylodon. When Doctor
Moreno said tiger, I asked if he did not mean jaguar; but he said no,
that he meant a huge cat like an Old World lion or tiger; I do not know
with what modern feline its affinities were closest. The discovery of
the comparatively fresh remains of the horse gave rise in some quarters
to the belief that it was possible this species of horse survived to the
day the Spaniards came to the Argentine and was partly ancestral to the
modern Argentine horse; but the supposition is untenable, for the horse
in question represents a very archaic and peculiar type, with
specialized legs and an extraordinary skull, and could not possibly have
had anything to do with the production of the wild, or rather feral,
horses of the pampas and the Patagonian plains. Of the mylodon Doctor
Moreno found not only comparatively fresh bones, with bits of sinew,
but dried dung—almost as large as that of an elephant—and some big
pieces of skin. The skin was clothed with long, coarse hair, and small
ossicles were set into it, making minute bony plates. Doctor Moreno gave
me a fragment of the skin, and also bones and dung; they are now in the
American Museum of Natural History. The discovery gave rise to much
fanciful conjecture; it was even said that the mylodon had been
domesticated and kept tame in the caves; but Doctor Moreno laughed at
the supposition and said that it lacked any foundation in fact. He also
said that, contrary to what has sometimes been asserted, the age of the
remains must be estimated in thousands, possibly ten thousands, and
certainly not hundreds, of years.
There is no need of fanciful guesswork in order to enhance the startling
character of the discovery. It seems to show beyond question that the
early hunting savages of southernmost South America lived among the
representatives of a huge fauna, now wholly extinct, just as was true of
the earlier, and far more primitive, hunting savages of Europe.
Save in tropical Africa and in portions of hither and farther India this
giant fauna has now everywhere died out. In most regions, and in the
earlier stages, man had little or nothing to do with its destruction.
But during the last few thousand years he has been the chief factor in
the extermination of the great creatures wherever he has established an
industrial or agricultural civilization or semicivilization. The big cat
he has warred against in self-defense. The elephant in India has been
kept tame or half tame. The Old World horse has been tamed and
transplanted to every portion of the temperate zones, and to the dry or
treeless portions of the torrid zone.
Around the Mediterranean, the cradle of the ancient culture of our race,
we have historic record of the process. Over three thousand years ago
the Egyptian and Mesopotamian kings hunted the elephant in Syria. A
thousand years later the elephant was a beast of war in the armies of
the Greeks, the Carthaginians, and the Romans. Twenty-five hundred years
ago the lion was a dreaded beast of ravin in the Balkan Peninsula and
Palestine, as he was a hundred years ago in North Africa; now he is to
be found south of the Atlas, or, nearing extinction, east of the
Euphrates. Seemingly the horse was tamed long after the more homely
beasts, the cattle, swine, goats, and sheep. He was not a beast for
peaceful uses; he was the war-horse, whose neck was clothed with
thunder, who pawed the earth when he heard the shouting of the captains.
At first he was used not for riding, but to draw the war chariots.
Rameses and the Hittites decided their great battles by chariot charges;
the mighty and cruel Assyrian kings rode to war and hunting in chariots;
the Homeric Greeks fought in chariots; Sisera ruled the land with his
chariots of iron; and long after they had been abandoned elsewhere war
chariots were used by the champions of Erin. Cavalry did not begin to
supersede them until less than a thousand years before our era; and from
that time until gunpowder marked the beginning of the modern era the
horse decided half the great battles of history.
But with this process primitive man had nothing to do. He was and, in
the few remote spots where he still exists unchanged, he is wholly
unable even to conceive of systematic war against the lion, or of trying
to tame the horse or elephant. These three, alone among the big beasts
of the giant fauna in which the age of mammals had culminated, once
throve in vast numbers from the Cape of Good Hope and the valley of the
Nile northward to the Rhone and the Danube, eastward across India and
Siberia, and from Hudson Bay to the Straits of Magellan. They were
dominant figures in the life of all the five continents when primitive
man had struggled upward from the plane of his ape-like ancestors and
had become clearly human. For ages he was too feeble to be as much of a
factor in their lives as they were in the lives of one another; and in
North America he never became such a factor. The great man-killing cat
was his dreaded enemy, to be fought only under the strain of direst
need. The horse became a favorite prey when he grew cunning enough to
devise snares and weapons. The elephant he feared and respected for its
power and occasional truculence, and endeavored to destroy on the
infrequent occasions when chance gave an opening to his own crafty
ferocity.
All this is true, at the present day, in portions of mid-Africa. I have
been with tribes whom only fear or imminent starvation could drive to
attack the lion; and I have seen the naked warriors of the Nandi kill
the great, maned manslayer with their spears. Again and again, as an
offering of peace and good-will, I have shot zebras for natives who
greedily longed for its flesh. My son and I killed a rogue elephant bull
at the earnest petition of a small Uganda tribe whose crops he had
destroyed, whose field watchers he had killed, and whose village he
menaced with destruction.
Of all the wonderful great beasts with which primitive man in his most
primitive forms has been associated, the three with which on the whole
this association was most wide-spread in time and space, were the horse,
the lion, and the elephant.
