AND PUMPING MACHINERY. BY FREDERICK COLYER, M. INST. C.E., M. INST. M.E., E. & F. N. SPON, 16, CHARING CROSS. NEW YORK: 44, MURRAY STREET. 1882. 16332 SVK •C72 PREFACE. THE favourable manner in which my book on Hydraulic and Steam Lifting Machinery has been received, has led me to write another treatise upon a subject of equal interest to the Profession. The object of the present work is the same as the last, not to discuss very rudimentary matters, but to afford practical information to Civil Engineers, Architects, and others, to assist those who require it and are specifying for such kind of work. It is hoped that the examples given, especially the data of working results, will prove of value to those who are seeking such information. All tables and other data may be relied upon; facts only are stated, and no theories entered into. I have adopted the same plan as before, in writing this work in a short terse style, for the purpose of offering only practical matter in as few words as possible, having found this generally most acceptable to those who want information given in a small compass. Most of the work described is from my personal experience, except those matters specially stated. I have, in conclusion, to offer my sincere acknowledgments to several firms for their kindness and courtesy in furnishing me with particulars and drawings of their respective kinds of work. In offering the book to my professional brethren, I must ask their kind indulgence for all shortcomings, and hope it may meet with as kind a reception as my former literary efforts.
