138 History of Gutta-Percha Willie, rushing, turned round to look, and saw him with one hand in a small wooden trough that ran along the wall, and with the other holding the tumbler in a stream of water that fell from the side of the trough into his bath. When the tumbler was full, he removed his hand from the trough, and the water ceased to overflow. He carried the tumbler to Hector, who drank, and said the water was delicious. Hector could not imagine how the running water had got there, and Willie had to tell him what I am now going to tell my reader. His grand- mother’s sovereign and his own hydraulics had brought it there. He had been thinking for some time what a pleasure it would be to have a stream running through his room, and how much labour it would save poor old Tibbie; for it was no light matter for her old limbs to carry all the water for his bath up that steep narrow winding stair to his room, He reasoned that as the well rose and overflowed when its outlet was stopped, it might rise yet farther if it were still confined; for its source was probably in the heart of one of the surrounding hills, and water when confined will always rise as high as its source. Therefore, after much medita- tion as to how it could be accomplished in the simplest and least expensive manner, he set about it as follows.
