Surveyor's Hand Book, 1908 e-bog

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. It has been my object to prepare a book for the use of the surveyor in the field, of convenient size and scope, and one that contains all the essentials for ordinary surveying. It is too much to hope that there are no errors in these pages, in theory Or example. The preliminary proof has been examined by twelve experienced surveyors and I am indebted to them for many valuable suggestions.<br><br>I am under lasting obligations to my colleagues, R. A. Thompson, Expert Engineer of the Texas Railway Commission; Edward C. H. Bantel, Professor of Civil Engineering; and Stanley P. Finch, Adjunct-Professor in Civil Engineering of the University of Texas. In addition to this assistance I have been aided by valuable suggestions from F. Lavis and Halbert P.Gillette, and from the following leading surveyors and engineers of Texas: C. F. H. von Blucher, Gustav Schleicher, B. F. Love, and W. D. Twichell.<br><br>The thanks of the author are hereby expressed to W. L. E. Gurley, Keuffel Esser, Eugene Dietzgen Co., and A. Wissler for many illustrations of instruments.<br><br>The traverse table has been omitted, as the ordinary ones are useless for angles not multiples of quarter degrees, and the large ones are books in themselves. As lands become more valuable, the transit survey is demanded where angles are read to the nearest minute, and for such surveys the small traverse tables are of no avail.<br><br>Tables I, II, III and IV are taken by permission from Henck's Field Book, while Table V is from Searles' Field Engineering.
