This volume, both in respect to matter and arrangement, is designed especially for the use of the cadets of the U. S. Military Academy, as a supplement to the course in General Astronomy at present taught them from the text-book of Professor 0. A. Young. It is therefore limited to that branch of Practical Astronomy which relates to Field Work, and more particularly to those subjects which are not discussed at sufficient length for practical work in Professor Young's volume. It is believed, however, that it will find a use ful application in the hands of Officers Of the Army, who may be called upon to conduct such explorations and surveys for military purposes as the War Department may from time to time direct.
The more usual methods of determining Time, Latitude, and Longitude, on Land, are explained, and the requisite. Reduction formulas are deduced and explained. In addition, there is given a short explanation Of the principles relating to the Construction Of Ephemerides, to the Figure of the Earth, the determination of Azimuths, and the projection of Solar Eclipses.
The instruments described are those used by the cadets in the Field and Permanent Observatories of the Military Academy dur~ ing the summer encampment.
