I knew it, replied a piping voice, and Lieutenant Telyanin, a small officer of the same squadron, entered the room.
A little later, about 1868, successful experiments were made with gas as a manufacturing fuel, and in 1872 the gas industry was fairly well established near Titusville by drilling a well and piping the gas for consumption both as fuel and light.
The penstock, three feet in diameter at this point, was a long black snake, carrying its mountain water to the small generating station, while adjacent black piping and frequent taps provided the ice that coated the cliff sides in gigantic clusters below.
With cast iron pipe this cannot be done, and no length of piping over 40 ft.
The piping takes a winding or zigzag course, and by the time the outlet is reached, the water it contains has reached a high temperature.
