THREE:It was all so simple and natural that Leona Lalage could say nothing for a moment. The stranger was standing up searching his pockets wildly. His eyes gleamed with hatred and defeat and baffled avarice. He knew that he had been made the victim of some trick, but there was no name for it yet.
THREE:To follow the same chain of reasoning still farther, and to show what may be gained by method and system in learning mechanics, it may be assumed that machine functions consist in the application of power, and therefore power should be first studied; of this there can be but one opinion. The learner who sets out to master even the elementary principles of mechanics without first having formed a true conception of power as an element, is in a measure wasting his time and squandering his efforts.3. The power developed is as the difference of volume between the feed-water forced into the boiler, and the volume of the steam that is drawn from the boiler, or as the amount of heat taken up by the water.
TWO:An engine lathe is for many reasons called the master tool in machine fitting. It is not only the leading tool so far as performing a greater share of the work; but an engine lathe as an organised machine combines, perhaps, a greater number of useful and important functions, than any machine which has ever been [122] devised. A lathe may be employed to turn, bore, drill, mill, or cut screws, and with a strong screw-feed may be employed to some extent for planing; what is still more strange, notwithstanding these various functions, a lathe is comparatively a simple machine without complication or perishable parts, and requires no considerable change in adapting it to the various purposes named.A GLORIOUS summer evening, quite refreshing after the exhausting heat of the day. Nature invited to restfulness, and so much the more cruel sounded the incessant thunder of the guns, which also boomed from the citadel. As soon as the Germans had taken possession of this old, dilapidated fortress they proceeded to drag their guns on to it, and trained them on the surrounding forts.
TWO:"We'll sit in the hall," said Lawrence. "We'll take it for granted that the owner is a hospitable man, and permit ourselves the luxury of tobacco."Prout nodded. It was some little time before the other spoke. His next question startled the detective.
