If the mercury descended to a certain mark on the scale on a mountain-top whose height was known, why was not this a means of measuring the heights of all other elevations? And so the beginning was made which, with certain modifications and corrections in details, is now the basis of barometrical measurements of heights. In hydraulics, also, Torricelli seems to have taken one of the first steps.
Altho Smith pierced the bowels of the great red mountain, that five thousand dollars was the first and last return of his labor. The mountain grew reticent of its golden secrets, and the flume steadily ebbed away the remainder of Smith's fortune. Then Smith went into quartz-mining; then into quartz-milling; then into hydraulics and ditching, and then by easy degrees into saloon-keeping.
Through the rainy twilight the logs could be seen raising their ghostly arms of protest. Slowly, without tumult, the jam formed. In the van the logs crossed silently; in the rear they pressed in, were sucked under in the swift water, and came to rest at the bottom of the river. The current of the river began to protest, pressing its hydraulics through the narrowing crevices.
Copernicus has shown that what appears real, to material sense and feeling, is absolutely unreal. Astronomy, optics, acoustics, and hydraulics are all at war with the testimony of the physical senses. This fact intimates that the laws of Science are mental, not material; and Christian Science demonstrates this. The rule of divinity is golden; to be wise and true rejoices every heart.
Hydraulics was his branch, and his frequent absences on missions about which he assumed an important and mystifying air, such as is, for that matter, usual in bumptious young men, never caused any comment or visible interest on the part of the others.
I see you are acquainted with hydraulics." I could not say that he was mistaken, for fear of offending him, so I simply bent my head, which might mean either yes or no. Thank God the king did not trouble to test my knowledge of the science of hydraulics, with which I was totally unacquainted.
This is an easy way of constructing the Chinese Pump, which is found described in treatises upon hydraulics. Such a pump could not, of course, be economically used in practice on account of the friction of the column of water against a wide surface in the interior of the tube.
The very necessities of its geographical position had forced it to pre-eminence in hydraulics and hydrostatics. It had learned to transform water into dry land with a perfection attained by no nation before or since. The wonders of its submarine horticulture were the despair of all gardeners in the world.
Nearly parallel with the horse-trough, as you go down "Maud's Rents," is that useful, and indeed indispensible, triumph of hydraulics, the pump. The taste and science displayed in its execution do credit to the engineer; and the soil in which it is imbedded, being argillaceous, partially encrusted with strontian, reflects equal honour on his geological attainments.
"Such a cascade will drown the honours of the Versailles fountains, if only the water can be raised to such a height. Are you sure of it, Wren?" "As certain as hydraulics can make me, sir," and the lesser man began drawing lines with his stick in the dust of the path in demonstration.
