Neither was Master Knips allowed to remain idle, for Ernest, now that he was in his possession, wished to train him to be of some use. With Jack's help he made a little basket of rushes, which he so arranged with straps that it might be easily fitted onto the monkey's back. Thus equipped, he was taught to mount cocoanut palms and other lofty trees, and to bring down their fruit in the hamper. Jack was not so successful in his educational attempts. Fangs, as he had christened his jackal, used his fangs, indeed, but only on his own account; nothing could persuade him that the animals he caught were not at once to be devoured, consequently poor Jack was never able to save from his jaws anything but the tattered skin of his prey. Not disheartened, however, he determined that Fangs could be trained, and that he would train him. These, and such like employments, afforded us the rest and recreation we required. I then turned shoemaker, for I had promised myself a pair of waterproof boots, and now determined to make them. Taking a pair of socks, I filled them with sand and then coated them over with a thin layer of clay to form a convenient mold; this was soon hardened in the sun, and was ready for use. Layer after layer of caoutchouc I brushed over it, allowing each layer to dry before the next was put on, until at length I considered that the shoes were of sufficient thickness. I dried them, broke out the clay, secured with nails a strip of buffalo hide to the soles, brushed that over with caoutchouc, and I had a pair of comfortable, durable, respectable- looking water-proof boots. I was delighted; orders poured in from all sides, and soon every one in the family was likewise provided for. One objection to Falconhurst was the absence of any spring close by, so that the boys were obliged to bring water daily from the stream; and this involving no little trouble, it was proposed that we should carry the water by pipes from the stream to our present residence. A dam had to be thrown across the river some way up stream, that the water might be raised to a sufficient height to run to Falconhurst. From the reservoir thus made we led the water down by pipes into the turtle's shell, which we placed near our dwelling, and from which the superfluous water flowed off through the hole made in it by Fritz's harpoon. This was an immense convenience, and we formally inaugurated the trough by washing therein a whole sack of potatoes. Thus day after day brought its own work, and day after day saw that work completed. We had no time to be idle, or to lament our separation from our fellow-creatures. One morning, as we were completing our spiral staircase, and giving it such finish as we were capable of, we were suddenly alarmed by hearing a most terrific noise, the roaring or bellowing of a wild beast; so strange a sound was it, that I could not imagine by what animal it was uttered.
