Later, the serendipitous drippings were augmented by additional piping, carrying excess water to spray even more surface of the rock walls.
In the United States the danger of the stoves that used to be employed for heating the interiors of the cars has been realized, and now the most common method is by steam taken from the locomotive boiler and circulated through the train in a line of piping, rendered continuous between the cars by flexible coupling-hose.
Compared with heating by hot water, steam-heating requires less piping, which, further, may be of much smaller diameter to attain a similar result, because of the higher temperature of the heat yielding surface.
Of late years a considerable amount of seamless tubing has been made, much in the same way as lead piping, by forcing the mixed rubber through a die, and curing as above.
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.
It is a mistake to stint the quantity of piping, since it is far more economical and better for the plants to have a larger surface heated moderately than a smaller surface heated excessively.
Amongst the finest of his classical pictures were - "Syracusan Bride leading Wild Beasts in Procession to the Temple of Diana" (1866), "Venus disrobing for the Bath" (1867), "Electra at the Tomb of Agamemnon," and "Helios and Rhodos" (1869), "Hercules wrestling with Death for the Body of Alcestis" (1871), "Clytemnestra" (1874), "The Daphnephoria" (1876), "Nausicaa" (1878), "An Idyll" (1881), two lovers under a spreading oak listening to the piping of a shepherd and gazing on the rich plain below; "Phryne" (1882), a nude figure standing in the sun; "Cymon and Iphigenia" (1884), "Captive Andromache" (1888), now in the Manchester Art Gallery; with the "Last Watch of Hero" (1887), "The Bath of Psyche" (1890), now in the Chantrey Bequest collection; "The Garden of the Hesperides" (1892), "Perseus and Andromeda" and "The Return of Persephone," now in the Leeds Gallery (1891); and "Clytie," his last work (1896).
Experiments on the velocity of sound in iron have been made on lengths of iron piping by J.
Rooks (Corvus frugilegus) and the Australian "magpie" or piping crow (Gymnorhina) are to be found in New Zealand, but only locally, especially the former.
I knew it, replied a piping voice, and Lieutenant Telyanin, a small officer of the same squadron, entered the room.
Imposing columns and pillars of ice were visible everywhere—massive icicles and mounds, built up from the spraying water tapped from the piping that paralleled the penstock.
