[ Boston, MA ]: [ F. D. Dickinson ] 1931. First Edition. Two volumes. 290 pages ; -525 pages. Small 8v. Publisher's red cloth gilt. With previous owner names on endpapers and page edges. Pencilled notation with Dickinson's name and address in rear of volume 1 [hence publication location inference]. Spines faded, overall minor wear to Vol. 1. Vol 2 appears to have a white substance on the boards previously (paint?) not mostly removed. Clean internally. Good. Cloth. 
Complete in two volumes. Vol 1 contains Part I, covering boilers, pumps, and heating and ventilating machinery. Vol 2 contains Part II covering engines, turbines and condensors. Highly pragmatic, these books use a question and answer format to get to proper operational procedures for the machinery covered. Part II has a note as well indicating that "this book is intended to fit a person for any examination for a license to have charge and operate the different plants operated by steam." Had I been an engineer in the period, I suspect these would have been on my shelf.
