While we were discussing the roast pig, and washing it down with fragrant mead, Fritz described the day's expedition.
They had set their traps near Woodlands, and had there captured the muskrats, attracting them with small carrots, while with other traps, baited with fish and earthworms, they had caught several beaver rats, and a duck-billed platypus. Hunting and fishing had occupied the rest of the day, and it was with immense pride that Jack displayed the kangaroo which he had run down with his swift courser. Contributions to the garden had not been forgotten, and Fritz handed over to his mother several cuttings from cinnamon and sweet-apple trees. Finally, when all the other treasures had been displayed, Fritz begged me to examine his thistles which he had gathered, thinking, he said, that it was a plant used in the manufacture of wool. He was perfectly right, for I recognized it at once as the "fuller's teazle," a plant whose sharp little thorns, which cover the stem and leaves, are used to raise the nap of cloth.
We resolved to be up betimes the following morning, that we might attend to the preparation of the booty, and as I now noticed that the boys were all becoming extremely drowsy, I closed the day with evening devotions.
The number of the creatures we killed rendered the removal of their skins a matter of no little time and trouble. It was not an agreeable task at any time, and when I saw the array of animals the boys had brought me to flay, I determined to construct a machine which would considerably lessen the labor. Among the ship's stores, in the surgeon's chest, I discovered a large syringe. This, with a few alterations, would serve my purpose admirably. Within the tube I first fitted a couple of valves, and then, perforating the stopper, I had in my possession a powerful air pump.
The boys stared at me in blank amazement when, armed with this instrument, I took up the kangaroo, and declared myself ready to commence operations.
"Skin a kangaroo with a squirt?" said they, and a roar of laughter followed the remark.
I made no reply to the jests which followed, but silently hung the kangaroo by its hind legs to the branch of a tree. I then made a small incision in the skin, and inserting the mouth of the syringe forced air with all my might between the skin and the body of the animal. By degrees the hide of the kangaroo distended, altering the shape of the creature entirely.
Still I worked on, forcing in yet more air until it had become a mere shapeless mass, and I soon found that the skin was almost entirely separated from the carcass. A bold cut down the belly, and a few touches here and there where the ligatures still bound the hide to the body, and the animal was flayed.
"What a splendid plan!" cried the boys; "but why should it do it?"
"For a most simple and natural reason," I replied; "do you not know that the skin of an animal is attached to its flesh merely by slender and delicate fibers, and that between these exist thousands of little bladders or air chambers; by forcing air into these bladders the fibers are stretched, and at length, elastic as they are, cracked. The skin has now nothing to unite it to the body, and, consequently, may be drawn off with perfect ease. This scientific fact has been known for many years; the Greenlanders make constant use of it; when they have killed a seal or walrus, they distend the skin that they may tow the animal more easily ashore, and then remove its hide at a moment's notice."
