Excerpt from Handbook of Calculations for Engineers
"I would give a thousand dollars if I knew the principles upon which my engine works."
This was the remark of a western engineer made to a gentleman who was admiring the performance of the steam plant under the charge of the former. "I can attend to every necessary thing about my whole apparatus; engine, boilers, pumps, pipes, and do all that is expected of an engineer, but I don't know why the steam does its work, and I would give a thousand dollars to know."
This work is prepared for those who, like the engineer whose words are quoted, wish to know, and are willing to pay the cost, in money and study.
Abraham Lincoln once said, in the early days of his opening manhood, with the warm enthusiasm characteristic of his noble mind, "That man who furnishes me with a good book is my best friend;" at the age of 18 he was the proud owner of six volumes.
The desire has been strong indeed, in the mind of the author, while compiling this work, upon a single page of which, at times, several days have been spent, that it might come to many aspiring men, with the same potent good, as the few books which Abraham Lincoln had access to in his early struggling days.
