× FORE:"Then I began to understand. You were only a little time from the room. Why did you go from the room? Ostensibly to see Captain Gifford off in his new autocar. Here was a possible solution. I saw Gifford later, and he told me that you had been larking off in his car for twenty minutes--long enough at that time of night to get to my chambers and back easily.

× FORE:I had expected it and believed the reports, but it hurt all the same. I had had intercourse with German soldiers almost exclusively; but that gave223 me a much better opportunity for observing their conduct, which roused in me a deep sympathy for the poor, oppressed Belgian people. That was why I was so sorry to hear of the fall of Antwerp, although I was not discouraged. Right would triumph, and the day come when the Belgian nation would shake off the foreign yoke of tyranny, and repair in peace and prosperity, under the sagacious rule of their king, what barbarians destroyed and pulled down.(1.) In what respect are air and water like belts and gearing, as means to transmit power?��(2.) What are some of the principal advantages gained by employing air to operate railway brakes?��(3.) Name some of the advantages of centralising motive power.��(4.) Are the conditions of working an engine the same whether air or steam is employed?

× FORE:No computations, drawings, or demonstrations of any kind will be employed to relieve the mind of the reader from the care of remembering and a dependence on his own exertions. Drawings, constants, formul?, tables, rules, with all that pertains to computation in mechanics, are already furnished in many excellent books, which leave nothing to be added, and such books can be studied at the same time with what is presented here.

× FORE:In forming an estimate of the value of his services, an apprentice sees what his hands have performed, compares it with what a skilled man will do, and estimates accordingly, assuming that his earnings are in proportion to what has been done; but this is a mistake, and a very different standard must be assumed to arrive at the true value of such unskilled labour.It is not the intention to discuss patent law, nor even to estimate what benefits have in the past, or may in the future, be gained to technical industry by the patent system, but to impress engineering apprentices with a better and more dignified appreciation of their calling than to confound it with chance invention, and thereby destroy that confidence in positive results which has in the past characterised mechanical engineering; also to caution learners against the loss of time and effort too often expended [161] in searching after inventions.

× FORE:"I don't doubt it," Leona said coolly. Her restless eyes were seeking a way of escape. "But many would say it was no forgery at all. You cannot prove that I had anything to do with it. There, let me pass." She advanced, but Charlton waved her back.

× FORE:The most perfect castings for gear wheels and pulleys and other pieces which can be so moulded, are made by drawing the patterns through templates without rapping. These templates are simply plates of metal perforated so that the pattern can be forced through them by screws or levers, leaving the sand intact. Such templates are expensive to begin with, because of the accurate fitting that is required, especially around the teeth of wheels, and the mechanism that is required in drawing the patterns, but when a large number of pieces are to be made from one pattern, such as gear wheels and pulleys, the saving of labour will soon pay for the templates and machinery required, to say nothing of the saving of metal, which often amounts to ten per cent., and the increased value of the castings because of their accuracy.

× FORE:��The life preserver snapped out of his hand!�� Larry muttered, giving up his effort to locate the moving objects in the glass and using his unaided eyes to view the tragedy��or whatever it would prove to be.
