This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1889 edition. Excerpt: ...and makes a man feel as sure of what he is doing as he feels physically secure when ltis feet are on a solid rock. The latter is a shadow and a delusion. The conceited man is really aware of his own lack of skill, but he presumes on other people's ignorance of tltc fact, and profcsews to know and understand things of which he has no actual knowledge. Self-confidence in an engineer comes from a knowledge of his business in general, and a thorough acquaintance witlt every part of the plant of which he has charge. This knowledge should not only be perfect as to its present condition, but it should refer as well to its history, length of time it has been in service, what repairs and alterations have been made, and why. A man may say that he cares nothing for the history of his plant, so long as he knows how it is now, but this is not just so; for on what has been done to a plant, and how it has been run, very much may depend. It is valuable to know what has happened to any of the apparatus, and how the trouble was gotten over or repaired. Quite often a hint can be got from what has taken place, that will enable one to avoid the same thing or to better repair damages, should it occur again. Don't try to improve the plant yott have just taken charge of, too fast, for the first impressions may be based on imperfect knowledge of the reasons why things arc as you flnd them, During the first week the writer held a certain position, he improved a steam pipe, that started from the boiler room, dropped 18 feet, went across an alley way 11 feet wide, and up again on the other side to just opposite where it had started from. I pulled this out, run the pipe directly across, and covered it nicely with rtsltestos board, fclt canvas, and paint. more
