"Time passed by. I had furnished steam hammers to the principal foundries in England. I had sent them abroad, even to Russia. At length it became known to the Lords of the Admiralty that a new power in forging had been introduced."

“We may fill our purses, but we pay a heavy price for it in the loss of picturesqueness and beauty.”

“The characteristic feature of our modern mechanical improvements, is the introduction of self-acting tool machinery. What every mechanical workman has now to do, and what every boy can do, is not to work himself, but to superintend the beautiful labor of the machine. The whole class of workmen that depend exclusively on their skill is now done away with. Formerly I employed four boys to every mechanic. Thanks to these new mechanical combinations, I have reduced the number of grown-up men from 1.500 to 750. The result was a considerable increase in my profits.”

“Everything connected with war and warlike exploits is interesting to a boy.”

“The arrangement we greatly preferred was to employ intelligent, well-conducted young lads, the sons of labourers or mechanics, and advance them by degrees according to their merits.”

“In all well-conducted concerns the law of "selection of the fittest" sooner or later comes into happy action, when a loyal and attached set of men work together harmoniously for their own advantage as well as for that of their employers.”

“My first essay at making a steam engine was when I was fifteen. I then made a real working; steam-engine, 1 3/4 diameter cylinder, and 8 in. stroke, which not only could act, but really did some useful work; for I made it grind the oil colours which my father required for his painting. Steam engine models, now so common, were exceedingly scarce in those days, and very difficult to be had; and as the demand for them arose, I found it both delightful and profitable to make them; as well as sectional models of steam engines, which I introduced for the purpose of exhibiting the movements of all the parts, both exterior and interior. With the results of the sale of such models I was enabled to pay the price of tickets of admission to the lectures on natural philosophy and chemistry delivered in the University of Edinburgh. About the same time I was so happy as to be employed by Professor Leslie in making models and portions of apparatus required by him for his lectures and philosophical investigations, and I had also the inestimable good fortune to secure his friendship. His admirably clear manner of communicating a knowledge of the fundamental principles of mechanical science rendered my intercourse with him of the utmost importance to myself. A hearty, cheerful, earnest desire to toil in his service, caused him to take pleasure in instructing me by occasional explanations of what might otherwise have remained obscure.”
