This early works was originally published in 1885. It contains plain directions for attaching the indicator, taking diagrams, computing the horse power, drawing the theoretical curve, calculating steam consumption, determinining economy, locating derangement of valves, and making all desired deductions; also tables required in making the necessary computations, and an outline of current practice in testing steam engines and boilers. Much of the information contained within will still be found to be useful and practical today. Many of the earliest books, particularly those dating back to the 1900's and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
