TWO:The first and, perhaps, the most important matter of all in founding engineering works is that of arrangement. As a commercial consideration affecting the cost of manipulation, and the expense of handling material, the arrangement of an establishment may determine, in a large degree, the profits that may be earned, and, as explained in a previous place, upon this matter of profits depends the success of such works.

TWO:"But it is not in the least beyond me," Lawrence remarked coolly, as he reached for a cigarette. "To a certain extent I hold the key to the situation. Accident strengthens my hands, as it generally does in dealing with people of this kind. And I am going to make a powerful new ally in this new business. I need not ask you if you are personally acquainted with Maitrank, Isidore?"

TWO:(1.) Why have belts been found better than shafts for transmitting power through long distances?��(2.) What are the conditions which limit the speed of belts?��(3.) Why cannot belts be employed to communicate positive movement?��(4.) Would a common belt transmit motion positively, if there were no slip on the pulleys?��(5.) Name some of the circumstances to be considered in comparing belts with gearing or shafts as a means of transmitting power.

TWO:VII.We now pass to a form of supernaturalism more characteristic than any other of the direction which men��s 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.

TWO:III.

TWO:An apprentice must guard against the too common impression that the engine, cylinder, piston, valves, and so on, are the main parts of steam machinery, and that the boiler and furnace are only auxiliaries. The boiler is, in fact, the base of the whole, that part where the power is generated, the engine being merely an agent for transmitting power from the boiler to work that is performed. This proposition would, of course, be reached by any one in reasoning about the matter and following it to a conclusion, but the fact should be fixed in the mind at the beginning.

TWO:"Did Countess Lalage allude to it this morning?" he asked.
