Animals, however, were very plentiful all around. Stags, elks, aurochs, horses, and the large pachyderms multiplied very rapidly in the wide solitudes, the pasture lands of which afforded them a constantly renewed supply of food, and the beasts of prey in their turn found an easy prey in the ruminants.15 The ways of animals do not change, and the travellers who are exploring the interior of Africa tell us that now, as in the day we are trying to recall, hundreds of elephants and rhinoceroses congregate in a limited area, whilst innumerable herds of giraffes, zebras, and gazelles graze peacefully in the presence of man, whose destructive powers they have not yet learnt to dread. Delegorgue speaks of one lake peopled by more than one hundred hippopotami, and of a region less than three miles in diameter containing six hundred elephants. Livingstone tells us that he saw troops of more than four thousand antelopes pass at a time, and that these animals showed absolutely no fear. We may give a yet more curious instance. Captain Gordon Cumming, crossing the plains stretching away on the north of the Cape, saw troops of gazelles and antelopes, compelled by a long drought to migrate in search of the water indispensable to them, and be describes with enthusiasm one of these migrations, telling us that the plain was literally covered with animals, the hurrying herds defiling before him in an endless stream. On the evening of the same day, a yet more numerous herd passed by in the same direction, the numbers of which were absolutely incalculable, but which, according to Cumming, must have exceeded several hundred thousand. Such must have been animal life in Europe in Quaternary times. “Grand indeed,” cries Hugh Miller, “was the fauna of the British Isles in those days. Tigers, as large again as the biggest Asiatic species, lurked in the ancient thickets; elephants, of nearly twice the bulk of the largest individuals that now exist in Africa or Ceylon, roamed in herds; at least two species of rhinoceros forced their way through the primeval forest, and the lakes and rivers were tenanted by hippopotami as bulky and with as great tusks as those of Africa.”16
