FORE:As reading books of fiction sometimes expands the mind and enables it to grasp great practical truths, so may a study of abstract principles often enable us to comprehend the simplest forms of mechanism. Even Humboldt and Agassiz, it is said, [32] resorted sometimes to imaginative speculations as a means of enabling them to grasp new truths.Once upstairs Balmayne followed. There was nobody on the landing.

FORE:CHAPTER VII. MOTIVE MACHINERY.

FORE:

FORE:1. A conception of certain functions in a machine, and some definite object which it is to accomplish.Adventures incite to ever more risky undertakings, and we long constantly for more sensation. Such an experience prompted me to an arrangement with Mr. Tervooren, editor of Het Leven, to try to motor to the French frontier.

FORE:Once more, there was a cause of intellectual degeneration at work in the ancient world, which for us has almost ceased to exist. This was the flood of barbarism which enveloped and corrupted, long before it overwhelmed, the Hellenised civilisation of Rome. But if the danger of such an inundation is for ever removed, are we equally secure against the contagion of that intellectual miasma which broods over the multitudinous barbarian populations among whom we in turn are settling as conquerors and colonists? Anyone choosing to264 maintain the negative might point to the example of a famous naturalist who, besides contributing largely to the advancement of his own special science, is also distinguished for high general culture, but whom long residence in the East Indies has fitted to be the dupe of impostures which it is a disgrace even for men and women of fashion to accept. Experience, however, teaches us that, so far at least, there is little danger to be dreaded from this quarter. Instead of being prone to superstition, Anglo-Indian society is described as prevailingly sceptical or even agnostic; and, in fact, the study of theology in its lowest forms is apt to start a train of reflection not entirely conducive to veneration for its more modern developments. For the rest, European enlightenment seems likely to spread faster and farther among the conquered, than Oriental darkness among the conquering race.

FORE:Writers on mechanical subjects, as a rule, have only theoretical knowledge, and consequently seldom deal with workshop processes. Practical engineers who have passed through a successful experience and gained that knowledge which is most difficult for apprentices to acquire, have generally neither inclination nor incentives to write books. The changes in manipulation are so frequent, and the operations so diversified, that practical men have a dread of the criticisms which such changes and the differences of opinion may bring forth; to this may be added, that to become a practical mechanical engineer consumes too great a share of one's life to leave time for other qualifications required in preparing books. For these reasons "manipulation" has been neglected, and for the same reasons must be imperfectly treated here. The purpose is not so much to instruct in shop processes as to point out how they can be best learned, the reader for the most part exercising his own judgment and reasoning powers. It will be attempted to point out how each simple operation is governed by some general principle, and how from such operations, by tracing out the principle which lies at the bottom, it is possible to deduce logical conclusions as to what is right or wrong, expedient or inexpedient. In this way, it is thought, can [6] be established a closer connection between theory and practice, and a learner be brought to realise that he has only his reasoning powers to rely on; that formul?, rules, tables, and even books, are only aids to this reasoning power, which alone can master and combine the symbol and the substance.

FORE:He must have the diamonds back again. The old man could never have proved that they had come back once more into Leona Lalage's possession by means of a clever plan, but he was in a position now to say and do a great deal of mischief. But for the accident to the motor, things would have been different.
