Not only that, boys," he continued, rising, with a shout, "but the whole slope above the spring is a mass of seepage underneath, as if you'd played a hydraulic hose on it, and it's ready to tumble and is just rotten with quartz!"
I knew the arid garden, deep in the wayside dust, with its hurriedly planted tropical plants, already withering in the dry autumn sunshine, and washed into fictitious freshness, night and morning by the hydraulic irrigating-hose.
We are apt to attribute too much influence to the winds. Undoubtedly they are the origin of the evil that befalls us in storms, but they are not the immediate cause of the wholesale destruction that takes place annually among the shipping of the kingdom. It is the mighty hydraulic force of the sea, the tremendous lifting power of the waves, that does it all.
The learned pair looked like two Christians who had issued from their tombs to find no God in the heavens. Science had been powerless; acids, so much clear water; red potash had been discredited; the galvanic battery and electric shock had been a couple of playthings. "A hydraulic press broken like a biscuit!" commented Planchette.
Twice again the dentist left the road and took to the trail that cut through deserted hydraulic pits. He knew exactly where to look for these trails; not once did his instinct deceive him. He recognized familiar points at once.
The man was a machinist in the employ of the East River Lead Co., and had charge of a machine which converted molten lead into wire. This machine consists of a steel box into which the lead is forced, being pressed through an aperture 1/8 inch in diameter by hydraulic pressure of 600 tons. Reaching the air, the lead becomes hard and is wound on a large wheel in the form of wire.
The miners in this fashion go down until they reach the bed rock along which the water originally ran, and here they find the richest deposits. The other sort of heavy gold washing, employing powerful streams of water to tear down and wash out the soil of hillsides that cover or hold golden deposits, is known as "hydraulic mining."
The change in the habits of the beaver is probably due to the diminution of their numbers since the introduction of fire-arms, and to the tact that their hydraulic operations are more frequently interrupted by the encroachments of man.
He then puts in the plug again, fills up the box with water, throws in more clay, and repeats the process again and again until night, when he cleans up with a cradle or pan. The puddling-box is used only in small mining operations, and never with the sluice, or in hydraulic claims. Quicksilver-Machine.
Such, for instance, was the estimable man to whom I have repeatedly referred as a warm defender of tractoration, and a bitter assailant of its enemies. The story tells itself in the biographical preface to his poem. He went to London with the view of introducing a hydraulic machine, which he and his Vermont friends regarded as a very important invention.
