Hope's Wharf was connected with Port Erskine, a pool about twenty yards long by three or four wide, and communicated with the side of the lighthouse by Watt's Reach, a distance of about thirty yards. About eight o'clock that morning the bell rang for breakfast. Such of the men as were not already up began to get out of their berths and hammocks. To Ruby the scene that followed was very amusing.
I remove her playthings and her baby-books, and teach her a few of Dr. Watt's moral hymns." Olive sighed. She felt that this was not the way to teach the faith of Him who smiled with benign tenderness on the little child "set in the midst."
"Yes, sir; on some of these marks are written the names of remarkable victims, recurring at intervals; on others are inscribed the heads of villainy 'the black-hole, 'starvation, 'thirst, 'privation of exercise, 'of bed, 'of gas, 'of chapel, 'of human converse, 'inhuman threats, and the infernal torture called the 'punishment-jacket. Somewhat on the plan of 'Watt's Bibliotheca Britannica. So that you can at will trace any one of Mr.
In this way he employed and amused himself in the many long days during which he was confined to the house by ill health. It is at this stage the steam and kettle story takes its rise. Mrs. Campbell, Watt's cousin and constant companion, recounts, in her memoranda, written in 1798: Sitting one evening with his aunt, Mrs.
Watt's next and most important step was the one which brings us to talk of the steam-engine as it now is in the present day. This important step was the idea, of making the steam draw down the piston, as well as help to drive it up; in the first engines it was raised by the beam, and steam used only to cause a vacuum, so as to let the air drive it down.
The Watt engine appeared in 1782; the steamship in 1801; the locomotive thirteen years later, in 1814. Thus thirty-two years after its appearance Watt's steam-engine had conquered both sea and land. The sociologist may theorise, but plain people will remember that men do not gather grapes from thorns, nor figs from thistles.
For their land engines they still retain Mr. Watt's standard of power, which makes the actual and the nominal power identical; and an actual horse power is the equivalent of a cubic foot of water raised into steam every hour. Q. What is the proper proportion of fire grate per horse power?
If a very equable motion is required, a heavier or swifter fly wheel must be employed. Q. What is Boulton and Watt's rule for fly wheels?
The angular velocity is regulated by a Watt's governor, which secures an isochronism of the motion independently of the charge.
A course of independent experiments was essential, and upon this he entered as usual, determined to find truth at the bottom of the well and to get there in his own way. Here he came upon the fact which led him to the stupendous result. That fact was the existence of latent heat, the original discoverer of which was Watt's intimate friend, Professor Black.
