Jeff! warned Sandy.Considered as means for transmitting power, the contrast as to advantages and disadvantages lies especially between belts and gearing instead of between belts and shafts. It is true in extreme cases, such as that cited at Crewe, or in conveying water-power from inaccessible places, through long distances, the comparison lies between belts and shafts; but in ordinary practice, especially for first movers, the problem as to mechanism for conveying power lies between belts and gear wheels. If experience in the use of belts was thorough, as it is in the case of gearing, and if the quality of belts did not form so important a part in the estimates, there would be but little difficulty in determining where belts should be employed and where gearing would be preferable. Belts are continually taking the place of gearing even in cases where, until quite recently, their use has been considered impracticable; one of the largest rolling mills in Pittsburg, Pennsylvania, except a single pair of spur wheels as the last movers at each train of rolls, is driven by belts throughout.

There is, however, this to be remembered, that the considerations which more especially balance premiumssuch as a term at draughting, designing, and office servicemay be mainly acquired by self-effort, while the practical knowledge of moulding, forging, and fitting cannot; and an apprentice who has good natural capacity, may, if industrious, by the aid of books and such opportunities as usually exist, qualify himself very well without including the premium departments in his course.Prout nodded. It was some little time before the other spoke. His next question startled the detective.Suddenly I saw a boy about twelve years old in one of the burning streets. He waved his arms, rushed madly to and fro, calling for his father and mother, and his little brother and sisters. He was in danger of perishing in the fire, or being killed by the murderous bullet from a rifle. I ran after him, laid hold of him, and in spite of his resistance pulled him back. Fortunately I met a couple of kind, sober soldiers to whom I told the story, and who promised to send the boy away from the burning town.I guess I better explain, Jeff decided. I didnt think you was so suspicious and quick or Id of done different.There was no chewing gum in the craft!
