“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 carcase. 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 fibres, and that between these exist thousands of little bladders or air chambers: by forcing air into these bladders the fibres 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.”
The remaining animals were subjected to the same treatment, and, to my great joy, in a couple of days the skins were all off, and being prepared for use.
I now summoned the boys to assist me in procuring blocks of wood for my crushing machine, and the following day we set forth with saws, ropes, axes, and other tools. We soon reached the tree I had selected for my purpose, and I began by sending Fritz and
