FORE:Since Dick had already given the man a sidelight on Jeffs character by mentioning his superstitions, it occurred to Sandy that he might learn, from the strangers reply, how well he knew Jeff.A pressure wheel, like a steam-engine, must include running contact between water-tight surfaces, and like a rotary steam-engine, this contact is between surfaces which move at different rates of speed in the same joint, so that the wear is unequal, and increases as the speed or the distance from the axis. When it is considered that the most careful workmanship has never produced rotary engines that would surmount these difficulties in working steam, it can hardly be expected they can be overcome in using water, which is not only liable to be filled with grit and sediment, but lacks the peculiar lubricating properties [41] of steam. A rotary steam-engine is in effect the same as a pressure water-wheel, and the apprentice in studying one will fully understand the principles of the other.
FORE:139For set squares, or triangles, as they are sometimes called, no material is so good as ebonite; such squares are hard, smooth, impervious to moisture, and contrast with the paper in colour; besides they wear longer than those made of wood. For instruments, it is best to avoid everything of an elaborate or fancy kind; such sets are for amateurs, not engineers. It is best to procure only such instruments at first as are really required, of the best quality, and then to add others as necessity may demand; in this way, experience will often suggest modifications of size or arrangement that will add to the convenience of a set.
FORE:"You had better," Hetty said demurely--"you had better run away and see to your Duchess."
FORE:Notwithstanding the importance of this impulse, it does not represent the whole effect produced by Protagoras on philosophy. His eristic method was taken up by the Megaric school, and at first combined with other elements borrowed from Parmenides and Socrates, but ultimately extricated from them and used as a critical solvent of all dogmatism by the later Sceptics. From their writings, after a long interval of enforced silence, it passed over to Montaigne, Bayle, Hume, and Kant, with what redoubtable consequences to received opinions need not here be specified. Our object is simply to illustrate the continuity of thought, and the powerful influence exercised by ancient Greece on its subsequent development.

FORE:Castings, forgings, and general supplies for erecting can be easily brought to the erecting shop from the other departments on trucks without the aid of motive power; so that the erecting and foundry cranes will do the entire lifting duty required in any but very large establishments."Go on," said Leona. "Nothing seems to be concealed from you. Now please tell me what happens next."
FORE:We now pass to a form of supernaturalism more characteristic than any other of the direction which mens thoughts were taking under the Roman empire, and more or less profoundly connected with all the other religious manifestations which have hitherto engaged our attention. This is the doctrine of immortality, a doctrine far more generally accepted in the first centuries of the Christian era, but quite apart from Christian influence, than is supposed by most persons. Here our most trustworthy information is derived from the epigraphic monuments. But for them, we might have continued to believe that public opinion on this subject was faithfully reflected by a few sceptical writers, who were, in truth, speaking only for themselves and for the numerically insignificant class to which they belonged. Not that the inscriptions all point one way and the books another way. On the contrary, there are epitaphs most distinctly repudiating the notion of a life beyond the grave, just as there are expressions let fall by men of learning which show that they accepted it as true. As much might be expected from the divisions then prevailing in the speculative world. Of all philosophical systems, Epicureanism was, at this time, the most widely diffused: its adherents rejected the belief in another world as a mischievous delusion; and many of them seem to have carefully provided that their convictions should be recorded on their tombs. The monument of one such philosopher, dedicated to eternal sleep, is still extant; others are dedicated to safe repose; others, again, speak of the opposite belief as a vain imagination. A favourite epitaph with persons of this school runs as follows:I was nothing and became, I was and am no more, so much is true. To speak otherwise is to lie, for I shall be no more.358 Sometimes,234 from the depths of their unconsciousness, the dead are made to express indifference to the loss of existence. Sometimes, in what was popularly believed to be the spirit of Epicureanism, but was, in reality, most alien to it, they exhort the passer-by to indulge his appetites freely, since death is the end of all.Even a doctor of the Red Cross established at St. Hadelin College had been removed in his white overall and wearing his Red Cross armlet. This was Dr. Labye, who already had rendered signal services to the wounded Germans. In consequence of his detention twenty of them were left in the hospital without medical attendance....
FORE:Neither sixteen-year-old Larry Turner nor Dick Summers, a year his junior, had any more fear than had Sandy Maclaren, hardly thirteen and seated just back of the pilot who, in flying the four-place, low-wing airplane, had called back reassuringly.
