Excerpt from The Elements of Geodetic Astromy: For Civil Engineers This book was written for the students in the course in civil engineering at the Ohio State University and to put in permanent form the author's manner of presenting this subject. After an experience of over sixteen years in teaching geodetic astromy to engineering students, he is firmly convinced of the value of this subject as a training for the young engineer. Practical astromy gives, as thing else does, experience in precise measurement and in handling long and intricate calculations. The equipment which this book presupposes is t expensive. An investment of $4000 would be sufficient to provide amply for a class of twenty. In the derivation of formulae, the author has sought directness of method rather than elegance of mathematical analysis. In the numerical examples, taken from observations made at the Emerson McMillin Observatory, he has aimed to furnish the student with models of correct forms for te-book record as well as of correct forms for reduction sheets. He has placed much emphasis upon the theodolite, as that is the instrument of the engineer and the one above all others with which he should become familiar.
