Part 9

Not one of those animals is living now, and none of them is mentioned in any history or tradition whatever, and though there is no doubt that men living in Europe saw the mammoth alive (as you will find in the next chapter), they knew of no kind of writing in which to tell us of them; these fossils are the only records left, but they speak plainly enough of the time when England and the whole of Europe were inhabited by these races of huge animals.

The Megatherium.]

Now I must carry you away to South America, where there are more wonders. If I were to tell you of all the singular monsters people have found in the beds of the rivers there it would make a book of itself. You know what large rivers there are in that country, and how they run for thousands of miles through almost flat plains called “Pampas.” Well, these rivers have often changed their beds by cutting new channels in the soft soil. The old dry beds of the rivers are the burying-places of some most curious animals, but I have not room to tell you about more than one of them at present. He is called the Megatherium, which means “great beast.” His size and strength were enormous. The largest hippopotamus looks small by his side. His leg bones are bigger than your body. He was more like the sloth than any other living animal, but he could not climb. He stood on those huge, broad hind feet, with his strong tail as a sort of third leg, and tore down the branches of the trees to feed on, or even rooted them up to get at the leaves. Standing by his skeleton in the British Museum one feels quite a shrimp, and he looks strong enough to walk away comfortably with an elephant on his back.

Another immense animal inhabited South America at the time, which geologists have called Dinotherium, or “dreadful beast.” He was a relation of the mastodon, but his tusks were very curious. Instead of being in the upper jaw and turned upwards they stuck out from the lower jaw and curved downwards, giving him a very odd appearance. He most probably had a trunk like the mammoth or mastodon, but perhaps not so long. All these of course were vegetable feeders.

The Tertiary period is so remarkable for the numbers of animals more or less related to elephants and spread all over the world, that we might almost call it the “elephant age,” as the oolite has been named the “reptile age.” These elephantine animals abounded in Europe, Asia, and North and South America, and though none of this kind have yet been found in Australia and Africa, I cannot help thinking they will be discovered in Africa at all events, for there is no doubt that Africa and Europe were once joined.

Australia you know possesses that animal so unlike all others that when we first see it we are quite astonished—the kangaroo. The bones of a huge fossil kangaroo have been found in Australia which must have stood fourteen or fifteen feet high I should think when on its hind legs, or more than twice as large as any living now. Then there were giant birds in New Zealand (something like the ostrich) called dinornis or “dreadful bird.” These fellows had no wings, and they must have been very much taller than the ostrich or emu. To look at their leg bones you would think they were the bones of oxen instead of birds, they are so immensely thick and strong. I do not think any of these are living now, because they have been sought for carefully, and none of the natives even can say that they have seen one. But their skeletons are common in the surface earth, and their bones, cracked to get the marrow out of them, are often dug out of the heaps of refuse collected about ancient cooking places. So that they were used for food, and perhaps they have not been extinct—that is to say, died out—more than a few hundred years; and this is more likely because feathers are sometimes attached to the remains, and undecayed sinews on the feet. A human skeleton has been found in a grave in New Zealand, too, with the egg of one between its arms, and little piles of pebbles are often seen among their bones, where the stomach would be, which the bird swallowed to digest its food, just as many birds do now. The natives called it the Moa, and they have some traditions about it, and, all things considered, it is probably one of the most recent fossil animals, and that is the reason why I have left it to the last.

Now I dare say you will wish to know when the animals living now took the place of those I have described, and which have all passed away. This cannot be told with certainty, but you will see in the “Human Part” that Men were living when the mammoth, mastodon, and some other extinct animals, inhabited the Earth, and that the reindeer, ox, bear, wolf, hyena, &c., have survived to the present day.

Throughout these immense periods of time there are gaps which we cannot yet fill up. No one can yet say, for instance, when the last of the mammoths disappeared, and the first of their near relations, the Indian and African elephants, took their place. These are the missing parts of “the puzzle of life” which you may perhaps one of these days find when you come to study the subject, and when you have learned all that is known at present. But you may be sure of this, that throughout all time there has been progress, the lower forms of animal life have been followed by more perfect forms as the Earth grew older. It is true the lower forms of life have not all died out. These imperfect animals have run through all the ages—the chalk builder of the Cretaceous age lives in the ocean now—and there are many other simple animals which lived in Old Red Sandstone times, and are not extinct yet, but wherever a superior kind of animal has passed away another more perfect has taken its place. This will be seen at once if we compare the “Reptile Age” with the Tertiary. The great ichthyosaurus, plesiosaurus, and pterodactyl are gone, but now we have the more perfect crocodiles and birds. The mammoth is gone, but we have the elephant. There are no giant mosses or towering tree ferns, but our forest trees are more perfect and more varied. The plants which formed the coal forests and once clothed the Earth with beauty have dwindled away to the lowly forms which we must stoop to examine in swamps, and these humble plants are all the surviving relatives of their once noble family. The lordly oaks and elms, stronger, and even more lovely in the sweet drapery of their foliage, and much better fitted for our use, have succeeded all those soft-stemmed plants which grew so fast and were the best possible kind for forming coal.

When you are able to study what is called comparative anatomy you will see how wonderful the plan of creation is, and how beautifully it has been worked out by its great Designer. You will see in the bones of the reptiles of the oolite rocks a prophecy as it were of the birds and animals which were to come. What could be more prophetic of animals with the power of perfect flight than the leather-winged pterodactyl, half lizard and half bird? In some of these animals you will see bones only half formed, and useless to that creature, which were brought to perfection in later times, and became the most important part of the body.

It is very difficult for me to make all this plain to you, but if you are really interested in it you will go to a museum where the fossils are collected, and then I am very much mistaken if you do not find a new and strange world opened to you.

THE HUMAN PART.

The history of the human race is of course even more interesting than that of the plants and animals which lived so long before man and prepared the way for him, because man is the “crown of creation.”
