PREFACE
principles of both that should be known. Taken altogether, this work, I think, contains all the information that is necessary to intelligently study, design, install and operate a compressed pumping plant of any size or capacity.
I desire to express my thanks to the authors from whose works I have quoted and to the various manufacturers named in the text for furnishing the cuts needed.
