What an engineer says:
I beg to acknowledge receipt of your book on Gas, Gasoline and Oil Engines, by Hiscox, by registered mail. I am highly pleased with the book. It is the best on Oil Engines I have ever seen, is not intricate in the calculations, and the illustrations are excellent. Yours truly,
S. DALRYMPLE, Chief-engineer S.S. "Talune."
