FORE:These conditions of short range and great force are best attained by what may be termed percussion, and by machines which act by blows instead of positive and gradual pressure; hence we find that hand and power hammers are the most common tools among those of the smith-shop.

FORE:"Turn down Churton Street," Leona whispered. "There seems to be nobody at that corner. If we can only get round by way of Hill Crescent we may manage to escape yet. Once in the square we can baffle them.""I'm not going away till I've got them," he said doggedly.

FORE:We are now in a position to understand how far Epicurus was justified in regarding the expectation of immortality as a source of dread rather than of consolation. In this respect also, the survival of the fittest has determined that human92 nature shall not look forward with satisfaction to the termination of its earthly existence. Were any race of men once persuaded that death is the passage to a happier world, it would speedily be replaced by competitors holding a belief better adapted to the conditions of terrestrial duration. Hence, practically speaking, the effect of religious dogmas has been to make death rather more dreaded than it would have been without their aid; and, as already observed, their natural tendency has been powerfully stimulated by the cupidity of their professional expositors. The hope of heaven, to exist at all, must be checked by a considerably stronger apprehension of hell. There is a saying in America that the immortality of the soul is too good to be true. We suspect that the immortality in which most religious Americans still believe hardly deserves such a compliment; but it accurately expresses the incredulity with which a genuine message of salvation would be received by most men; and this explains why Universalism, with the few who have accepted it, is but the transition stage to a total rejection of any life beyond the grave. No doubt, in the first flush of fanaticism, the assurance of an easy admission to paradise may do much to win acceptance for the religion which offers it; but when such a religion ceases to make new conquests, its followers must either modify their convictions, or die out under the competition of others by whom mortal life is not held so cheap.

FORE:��But why did he shut off the ignition and pretend the engine had stopped��so handy to this old, abandoned estate?��"It's a great discovery, sir," said Prout. "I have found the brother of the murdered man."

FORE:Although a system but recently developed, the employment of hydraulic machinery for transmitting and applying power has reached an extended application to a variety of purposes, and gives promise of a still more extensive use in future. Considered as a means of transmitting regularly a constant amount [54] of power, water apparatus is more expensive and inferior in many respects to belts or shafts, and its use must be traced to some special principle involved which adapts hydraulic apparatus to the performance of certain duties. This principle will be found to consist in storing up power in such a manner that it may be used with great force at intervals; and secondly, in the facilities afforded for multiplying force by such simple mechanism as pumps. An engine of ten-horse-power, connected with machinery by hydraulic apparatus, may provide for a force equal to one hundred horse-power for one-tenth part of the time, the power being stored up by accumulators in the interval; or in other words, the motive power acting continuously can be accumulated and applied at intervals as it may be required for raising weights, operating punches, compressive forging, or other work of an intermittent character. Hydraulic machinery employed for such purposes is more simple and inexpensive than gearing and shafts, especially in the application of a great force acting for a considerable distance, and where a cylinder and piston represent a degree of strength which could not be attained with twice the amount of detail, if gearing, screws, levers, or other devices were employed instead.

FORE:Fifth.��The range and power of the blows, as well as the time in which they are delivered, is controlled at will; this constitutes the greatest distinction between steam and other hammers, and the particular advantage which has led to their extended use.It is to be regretted that there have not been books especially prepared to instruct mechanical students in the relations between heat, force, motion, and practical mechanism. The subject is, of course, treated at great length in modern scientific works, but is not connected with the operations of machinery in a way to be easily understood by beginners. A treatise on the subject, called "The Correlation and Conservation of Forces," published by D. Appleton & Co. of New York, is perhaps as good a book on the subject as can at this time be referred to. The work contains papers contributed by Professors Carpenter, Grove, Helmholtz, Faraday, and others, and has the advantage of arrangement in short sections, that compass the subject without making it tedious.

FORE:"I would give all I possess in the world to clear it, Lawrence."

FORE:There was no time to be lost, for she could hear Balmayne coming down the garden. And then a happy inspiration came to her. From her head she removed the gold and ornamented dagger, with its long steel pin. She stooped down. . .

FORE:Hetty clung to Bruce's arm as if fearful for her safety. Of course, he was absolutely innocent, but how far the world would believe it was quite another matter. For the girl was quick and clear-sighted, and it needed no explanation to show her Bruce's terrible position.
