If, for the future prevention of this wanton and dastardly outrage, no remedy could have been found, here was an end to the making of the Lake. But there were brains among the Prince’s Engineers, and one of them very cleverly constructed a most ingenious device for counteracting or stopping the flying sand. In a certain spot in one of the otherwise dry and sterile gorges, watered in some way not yet discovered, he had seen a very large number of bamboos growing. They were of all sizes; from the thickness of a lead pencil to the circumference of a man’s wrist; and being very sheltered from the wind, they were all extremely tall. Getting a huge quantity of them brought up from the gorge, he first had them cleared of inside pith so as to leave a free passage from end to end. Taking the thinner ones, he had tiny holes bored into them about half an inch apart. This done, he fitted them, straight up and down, into a frame of the thickest ones, twelve feet square. When a number of these squares had been so fitted, they were taken to the outside edge of the Trench, and there set up by means of props or stays, also made of bamboo. A long line of bamboo piping was then laid to each of the squares, and duly fitted into that portion of the frame which touched the ground. As can be seen, all that was now needed, was a supply of water rushing through the pipes to burst through the holes—no bigger than those in a gas burner—to make a water sprayer of astonishing value in beating down every grain of sand that came against it. Very ingenious also, was the way in which this feat was accomplished! An enormous basket-basin was first woven out of bamboo leaves and thoroughly stiffened with beeswax. It was then set upon pillars, made with stones taken from the ground, right against the opening to the Well. In appearance it looked something like the high round tanks one sees at railway stations. There was this curious difference, however, that through the bottom of the basin bamboo pipes came down, and these were joined to the other pipes that were to take the water to the squares. Now it has to be remembered, that when the trapdoor of the Magic Well was opened, the water shot upwards into the air. To permit of the basin being placed in position, and for other reasons, the door had been closed and the water shut off. To make it fall into the basin when it should be again released, a kind of stand-pipe, surmounted by a concave shield something the shape of a reaping hook, was so erected as to be behind and over the water as it would rise. The shield, like the basin, was made of waxed bamboo leaves.
