The revised edition of this book has been prepared for schools that desire a brief course free from mathematics. It is based upon the author's Elements of Astronomy, but many changes of arrangement have been made. In fact, everything has been carefully worked over and re-written to adapt it to the special requirements. Great pains has been taken not to sacrifice accuracy and truth to brevity, and no less to bring everything thoroughly down to date. The latest results of astronomical investigation will be found here. The author has endeavored, too, while discarding mathematics, to give the student a clear understanding and a good grasp of the subject. As a body of information and as a means of discipline, this book will be found, it is believed, of notable value. The most important change in the arrangement of the book has been in bringing the Uranography, or constellation tracing, into the body of the text and placing it near the beginning, a change in harmony with the accepted principle that those whose minds are not mature succeed best in the study of a new subject by beginning with what is concrete and appeals to the senses, rather than with the abstract principles. Brief notes on the legendary mythology of the constellations have been added for the benefit of such pupils as are not likely to become familiar with it in the study of classical literature. N.W. Rarrington, President of University of Washington, Seattle, Wash., formerly chief of the U.S. Weather Bureau, Washington, D.C.: "I shall take pleasure in commending it to schools requiring an astronomy of this grade. The whole series of Astronomies reflects credit on their distinguished author and shows that he appreciates the needs of the schools." Clarence E. Kelly, Prin. of High School, Haverhill, Mass.: "It seems to me the book is admirably adapted to its purpose, and that it accomplishes the difficult task of presenting to the student or reader not conversant with Algebra and Geometry, an excellent selection of what may with profit be given him as an introduction to the science of astronomy."
