New topics, as indicated above, have received a full share of attention, and while the book makes no claims to novelty, the name of the author is a guarantee of much originality both of matter and manner.
The book will be found especially well adapted for high school and academy teachers who desire a work for reference in supplementing their brief courses. The illustrations are mostly new, and prepared expressly for this work. The tables in the appendix are from the latest and most trustworthy sources. A very full and carefully prepared index will be found at the end.
The eminence of Professor Young as an original investigator in astronomy, a lecturer and writer on the subject, and an instructor of college classes, and his scrupulous care in preparing this volume, led the publishers to present the work with the highest confidence; and this confidence has been fully justified by the event. More than one hundred colleges adopted the work within a year from its publication.

This volume is a new work, and not a mere abridgment of the author’s General Astronomy. Much of the material of the larger book has naturally been incorporated in this, and many of its illustrations are used; but everything has been worked over, with reference to the high school course.
Special attention has been paid to making all statements correct and accurate as far as they go. Many of them are necessarily incomplete, on account of the elementary character of the work; but it is hoped that this incompleteness has never been allowed to become untruth, and that the pupil will not afterwards have to unlearn anything the book has taught him.
In the text no mathematics higher than elementary algebra and geometry is introduced; in the foot-notes and in the Appendix an occasional trigonometric formula appears, for the benefit of the very considerable number of high school students who understand such expressions. This fact should be particularly noted, for it is a special aim of the book to teach astronomy scientifically without requiring more knowledge and skill in mathematics than can be expected of high school pupils.
