Excerpt from The Introduction to Geodetic Surveying, in Three Parts: I. The Figure of the Earth; II. The Principles of Least Squares; III. The Field Work of Triangulation IN the first part of this book several lectures on the Figure of the Earth, prepared as an introduction to a course of study in Geodesy, are republished. In the second part is given a condensed presentation of the fundamental principles and rules of the Method of Least Squares, written especially for students, surveyors, and engineers who are unable to Spare the time required for the perusal of the larger books on the subject. The theoretical discussions have necessarily been omitted, but the fundamental ideas concerning adjustments, weights of observations, and probable error are fully explained, so that computations may be made intelli gently and not blindly. In the third part is presented a synopsis of the methods and computations required in the field work of precise triangulation, particularly in secondary geodetic work. Care has been taken to illus trate the rules and formulas by numerical examples, and to give problems exemplifying their applications. Thus the three parts of the book form an introduction, both theoretical and practical, to the science of Geodesy, and especially to Geodetic Surveying.
