Percival and others experienced in construction work had learned that efficiency and accomplishment depend entirely upon the concentration of force, and so, instead of piling hundreds of futile men on shore to create confusion, they adopted the plan of sending out daily detachments of fifty or sixty, to work in regular rotation until all available man power had been broken in and classified according to fitness and strength.
The commonwealth would beyond doubt have been a gainer, if either the aristocracy had directly introduced a hereditary rotation instead of election by the burgesses, or the democracy had produced from within it a real demagogic government.
There was not much wrong, but her engineer commander recommended a renewal of some of the spur wheels. The officers and crew went on short leave in rotation, a care and maintenance party was put in charge, and the builders placed a working gang on board which was occupied in shifts, by night and by day, in making good the defects.
"Joshua," said Mr. Maydig. "Why not? Stop it." Mr. Fotheringay looked at the moon. "That's a bit tall," he said, after a pause. "Why not?" said Mr. Maydig. "Of course it doesn't stop. You stop the rotation of the earth, you know. Time stops. It isn't as if we were doing harm." "H'm!" said Mr. Fotheringay. "Well," he sighed, "I'll try. Here!"
We amused ourselves by signalling, first to one ship, and, then, to the other brig, and so on, in rotation, from schooner to smack; and, thus occupied, the afternoon wagged on. Jacko was convicted of a few misdemeanours to-day, and the principal witness against him was his particular friend, Alfred, the boy. At midnight, the Trindelen light-ship bore west, distance six or seven miles.
But notwithstanding this, if a string had been suddenly stretched across in space above the east end of the building, and left there in free suspension, independent of all connection with the terrestrial surface, it would have taken longer for the huge structure to be trailed beneath it by the earth's rotation swift as that rotation is than it did for the sober and leisurely mass of metal to finish its beat from side to side.
"It is that during the movement of rotation of the globe our wire would have been rolled round it like a chain round a windlass, and it would inevitably have dragged us down to the earth again." "By the thirty-nine stars of the Union!" said Michel, "I have nothing but impracticable ideas to-day ideas worthy of J.T. Maston!
The cam plates being then given a slight motion of rotation by the help of socket levers the rectangular projections to be received by which are seen on the top edges of the cam plates in the figure the carriage, by its own commenced descent, gets again upon its rollers, and runs forward upon these at once into firing position.
The sensitiveness is likewise affected by the variations of temperature. To attain great sensitiveness it is necessary to have the small sphere s in the centre of the globe L, as otherwise the electrostatic action of the glass of the globe will tend to stop the rotation. The sphere s should be small and of uniform thickness; any dissymmetry of course has the effect to diminish the sensitiveness.
How the period of the moon's rotation is regulated by the earth's attraction on her molten lava-sheets, first at the surface, and now probably below the outer crust, has been graphically shown by Sir Robert Ball, but it cannot be doubted that once the moon was appreciably nearer to our globe than at present.
