The following extract from the report of a committee, made to the American Society of Mechanical Engineers at a recent meeting, gives an idea of the value of the new fuel: "Natural gas, next to hydrogen, is the most powerful of the gaseous fuels, and, if properly applied, one of the most economical, as very nearly its theoretical heating power can be utilized in evaporating water.
This plant will be in itself a very interesting exhibit. It is proposed to provide a capacity for evaporating not less than 440,000 pounds of water per hour. AN INTERESTING little plant in which the rise and fall of the tides is used as motive power for the generation of electricity is described in L'Electricien.
Some miles farther the wheels of the wagon plowed deep into the alluvial soil, where irregular creeks murmured in their beds, half hidden among giant reeds. By-and-by they skirted vast salt lakes, rapidly evaporating. The journey was accomplished without trouble, and, indeed, without fatigue.
"Oh!" he shouted, half-beside himself with rage; and, scrambling up, he made a rush with clenched fists at the two boys, who now stood perfectly still awaiting his onslaught. It was a thoroughly angry charge, but not a charge home; for Burney stopped some three or four yards short of the distance, with his rage evaporating fast and beginning to feel quite discreet.
Angelica balsam is obtained by extracting the roots with alcohol, evaporating and extracting the residue with ether.
It would be dangerous to repeat to a reader, probably quite uninterested in the controversy, Mr. Northcote's speech, in which he laid hold of some of those weak points which the Church, of course, has in common with every other institution in the world. Eloquence has a way of evaporating in print, even when the report is immediate.
In general, it may be said that irrigation is employed only in the seasons when the evaporating power of the sun and the capacity of the air for absorbing humidity are greatest, or, in other words, that the soil is nowhere artificially watered except when it is so dry that little moisture would be evaporated from it, and, consequently, every acre of irrigated ground is so much added to the evaporable surface of the country.
It is to be remembered that the soil is impregnated with both salt and natron in many of these upland districts, and the inhabitants may have eaten earth containing these ingredients, as they do for the same purpose in several places in the Old World. We disembarked after sailing to the end of these great evaporating pans, and found horses waiting to take us to the Bosque del Contador.
The vaporizer, properly so called, is not placed directly over the fire, and for this reason the production of a spheroidal state of the liquid is avoided. It consists of a vessel, 44, into which the liquid is led by a pipe, 43. The cast-iron evaporating vessel, 14, is provided with appendages, 14 bis, which dip into the liquid and bring about its evaporation.
We thought only of the conclusion. Where the actual winning-post could be we had given up trying to conjecture. "It seems," Haigh remarked once, "that those two fools have made up their minds to race round this five-franc bit of an island for so long as we three fools choose to chivy them. It's a mad set-out whichever side you take it from, and the fun's evaporating.
