Buch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - PREFACE: With the readers indulgence, we will explain just what this small book is by first defining what it is not. It is not a compendium of statistics. Neither is it a record of the actual performance of specific dredges of all kinds and under all conditions nor yet a compilation of dredging cost data. Such information is already minutely available in the Annual Reports of the Chief of Engineers, U. S. Army, and in the records of the various departments of commonwealths and municipalities controlling dredging operations in their respective localities. It has been the authors intention first to describe the principal types of dredge in such manner as to impart a fundamental working knowledge of their construction and operation, and then to consider, in concise form, the usual problems confronting the engineer in the conception and accomplishment of dredging projects. Because of the fact that most literatureupon the subject, having been presented in the form of papers and articles in the technical periodicals, isnot onlynot readily available, but incomplete, in that each as a rule treats only of one particular phase of the subject, it is thought that a need exists for a comprehensive treatise, which should be helpful alike to the student and engineer. To fill thiswant hasbeen the authors objective. The importance of the subject, while not always ap- parent to the layman, is obviously paramount, involving the expenditure of many millions of dollars annually for the necessities of commercial life.
