But, to describe, to show how beautiful and how truly admirable in finish and in powers of execution is the modern steam engine, is not indeed the highest, but quite one Of the pleasantest and most useful of tasks, and the author feels that it is Within his range Of power, i. E., to admire and to describe and in a measure at the same time to instruct. With a high appreciation for noble results achieved, this book is dedicated to the Designers and Builders of the modern steam engine, and the added desire is now expressed, andithe kindly suggestion made that these two, the designers and builders of high class engines, should join in fraternal association and each quarter year meet to consult upon matters of mutual profit, to feast together and go away with a wish to meet such good company again.
