But of all parts of Europe, that in which they are found in greatest numbers is the valley of the Upper Arno. We find there a perfect cemetery of Elephants. These bones were at one time so common in this valley, that the peasantry employed them, indiscriminately with stones, in constructing walls and houses. Since they have learned their value, however, they reserve them for sale to travellers.

The bones and tusks of the Mammoth are met with in America as well as in the Old World, scattered through Canada, Oregon, and the Northern States as far south as the Gulf of Mexico. Cuvier enumerates several places on that continent where their remains are met with, mingled with those of the Mastodon. The Russian Lieutenant Kotzebue found them on the north coast of America, in the cliffs of frozen mud in Eschsholtz Bay, within Behring’s Strait, and in other distant parts of the shores of the Arctic Seas, where they were so common that the sailors burnt many pieces in their fires.

It is very strange that the East Indies, that is, one of the only two regions which is now the home of the Elephant, should be almost the only country in which the fossil bones of these animals have not been discovered. In short, from the preceding enumeration, it appears that, during the geological period whose history we are recording the gigantic Mammoth inhabited most regions of the globe. Now-a-days, the only climates which are suited for the existing race of Elephants are those of Africa and India, that is to say, tropical countries; from which we must draw the conclusions to which so many other inferences lead, that, at the epoch in which these animals lived, the temperature of the earth was much higher than in our days; or, more probably, the extinct race of Elephants must have been adapted for living in a colder climate than that which they now require.

Among the antediluvian Carnivora, one of the most formidable seems to have been the Ursus spelæus, or Cave-bear ([Fig. 183]). This species must have been a fifth, if not a fourth, larger than the Brown Bear of our days. It was also more squat: some of the skeletons we possess are from nine to ten feet long, and only about six feet high. The U. spelæus abounded in England, France, Belgium, and Germany; and so extensively in the latter country, that the teeth of the antediluvian Bear, as we have already stated, formed for a long time part of its materia medica, under the name of fossil licorn. [Fig. 183] represents the skull of the Cave-bear.

At the same time with the Ursus spelæus another Carnivore, the Felis spelæus, or Cave-lion, lived in Europe. This animal is specifically identical with the living Lion of Asia and Africa: but since in these early times he had not to contend with the hunter for food, he was, on the whole, considerably larger than any Lion now existing on the earth.
