Steam-power, horse-power, man-power, and water-power are good inventions, but nature has provided women with a moral power, in comparison with which all other powers are nothing; we may call it rattle-power.
We travel by the aid of steam-power, and we think and speak of a locomotive or a steamboat as we once thought and spoke of a horse or a man; and no little feeling of self-sufficiency is engendered by the conclusion that this new source of power has been brought under control and put to work in our day.
Another novelty of the time, with which George Stephenson had to contend, was the substitution of atmospheric pressure for locomotive steam-power in the working of railways. The idea of obtaining motion by means of atmospheric pressure is said to have originated with Denis Papin, more than 150 years ago; but it slept until revived in 1810 by Mr.
Having briefly referred to the various views entertained in regard to the steam-power with which the navy should be furnished, it will be seen that a difference of opinion on this important subject may most reasonably be entertained.
There will soon be in operation 3 ginning- and pressing-stations run by steam-power, besides a dozen or more hand-gins. This, I believe, tells the whole story. My health is very good. I hope you will write me often, because your letters are always so interesting and helpful.
This vessel was the first European steamer that pushed out into the more dangerous navigation of the open sea-coast. She was purchased by a company in London. On her passage up, she was as nearly as possible wrecked on a lee-shore, but, by her steam-power, was enabled to go straight against the wind, at the rate of three and a half knots an hour, and so escaped.
It will be obvious from the foregoing that if it were attempted to supply the great energy necessary for this operation by direct application of steam-power, an engine of enormous horse-power would be required, and even then it is doubtful if one could be constructed of sufficient strength to withstand the terrific strains that would ensue.
Were they grown men? Had they reasoning minds? Were they of the great races that had given the world steam-power, electric power, anæsthesia, and antiseptics? Had they the religion of Christ? Had they an inheritance of great ages of art, literature, music, and philosophy? Did they guard the treasures of their libraries and galleries?
Generally, water so secured will have to be raised to an elevated reservoir by some mechanical force. If the demand is to be a large one, and if the community can afford the cost, the most reliable plan will be to use steam-power for pumping; but in smaller places, and where economy is a great object, wind-power may serve an excellent purpose.
Making a large wooden wheel he rigged it after the style of the present spile-drivers, and in the course of two or three weeks, had the satisfaction of seeing the spiles driven with greatly increased speed and effect by steam-power.
