This appeal being more pressing as well as more important than Jack's, I snatched up an oar and hastened to their assistance.
Sure enough a large turtle was scrambling quickly toward the water, and was within a few paces of it, although Ernest was valiantly holding on by one of its hind legs.
I sprang down the bank, and making use of the oar as a lever, we succeeded with some difficulty in turning the creature on its back.
It was a huge specimen, fully eight feet long, and being now quite helpless, we left it sprawling, and went to inspect Jack's mammoth skeleton, which, of course, proved to be neither more nor less than that of the whale. I convinced him of the fact by pointing out the marks of our feet on the ground, and the broken jaws where we had hacked out the whalebone.
"What can have made you take up that fancy about a mammoth, my boy?"
"Ernest put it into my head, father. He said there seemed to be the skeleton of an antediluvian monster there, so I ran to look closer, and I never thought of the whale, when I saw no fish bones. I suppose Ernest was joking."
"Whales are generally considered as fishes by those little acquainted with the animal kingdom, but they belong to the class of mammals, which comprises man, the monkey tribes, the bats, the dogs and cats, all hoofed animals, whales and their allies, with other animals, the last on the list being the sloth.
"The name by which they are distinguished is derived from the Latin word, 'mamma,' a breast, and is given to them because all the species belonging to this class are furnished with a set of organs called the mammary glands, secreting the liquid known as milk, by which the young are nourished.
"The bones of the whale differ from those of animals simply in being of a hollow construction, and filled with air so as to render the carcass more buoyant. The bones of birds are also hollow, for the same reason, and in all this we see conspicuously the wisdom and goodness of the great Creator."
"What a marvelous structure it is, father!" said Fritz. "What a ponderous mass of bones! Can we not make use of any of them?"
