Excerpt from The Theory and Practice of Surveying: Designed for the Use of Surveyors and Engineers Generally, but Especially for the Use of Students in EngineeringIn each new edition of this volume some additions, corrections, and minor changes have been made. In the present edition there are so many changes and additions that they deserve to be specially mentioned.To Part I., on Surveying Instruments, have been added descriptions and cuts of the architect's level, new level-rod targets and bubbles, Wood's double sextant, and the cross-section polar protractor used in the New York aqueduct tunnel.The table of Magnetic Declination Formul?, on pages 25 to 28 inclusive, has been replaced entire with the new table issued by the United States Coast and Geodetic Survey, 1890, and Plate I. has been redrawn and brought down to 1890.The chapter on Land Surveying has been entirely recast. A considerable amount of new matter on the subject of monuments, and the principles and laws governing the re-survey of lands, have been added. The author wishes here to acknowledge his debt to Bellows and Hodgeman's little work on Land Surveying for much of the original matter from which he has deduced his general rules. In that work decisions are abstracted, and references given to the cases themselves, and the land surveyor would do well to obtain a copy of this valuable work.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
