Excerpt from A Treatise on Surveying: In Which the Theory and Practice Are Fully Explained; Preceded by a Short Treatise on Logarithms; And Also by a Compendious System of Plane Trigometry; The Whole Illustrated by Numerous Examples Surveying. This is the method employed in extensive geodetic operations. The details of this method are so complex that a volume - t a chapter - would be required for their development. All that has been attempted is to give some of the more simple principles. Chapter VII. treats of Laying out and Dividing Land. It is believed that many of the demonstrations in this chapter will be found to be much more simple than those usually given, almost all of them having been reduced to the development of a single principle. On a subject of this kind, which has so long occupied the attention of mathematicians, any thing new could hardly be expected. It has been the aim of the author to select the best methods, t to introduce any thing merely because it was new. Chapter IX. contains a treatise on Practical Astromy, embracing all that is needed for the surveyors purposes or is practicable with his instruments. Various methods of running meridian lines, and of determining the latitude and the time of day, are fully explained. The concluding chapter (X.) is devoted to the subject of the Variation of the Compass. In it will be found information of great value to the practical surveyor. The tables of variation are in all cases drawn from the most recent and authentic sources. In the preparation of this treatise the author has consulted various well-kwn English and American mathematical works. To Professor Gillespie's excellent Treatise on Land Surveying (D. Appleton Co., New York, ) especially, the author is indebted for very valuable hints, particularly in the directions for practice, the descriptions of the instruments, and various new methods of presenting important points. Some of these are referred to in their places. The typographical peculiarities of this volume, in the headings of articles, c, were also suggested to the publishers by those of the work of Dr. Gillespie.
