A Beginner's Star=Book
With Charts of the Moon, Star Maps on a New Plan, and an Easy Guide to the Astronomical Uses of the Opera-Glass, the Field-Glass, and the Telescope
By Kelvin McKready
Crown 8vo. Illustrations
While basing his book upon the best precedents, European and American, Mr. McKready takes the beginner directly to the objects of the sky without the employment of difficult technical detail. Just as a pleasurable knowledge of the flowers may precede a technical knowledge of botany, so—without appreciating the science of astronomy on its mathematical side—Mr. McKready is first of all concerned with the task of making the stars interesting. The book will be distinguished from other volumes on popular astronomy by a somewhat novel system of mapping, and by an unusually full discussion of the uses of the simpler astronomical instruments. Here too, however, the treatment is definite and practical. Questions of optical theory and construction are subordinated to the pointing out, by the author, of the objects that can be seen, and of the satisfactions that may be obtained, first with the unaided eye (the fundamental optical instrument), and then with the opera-glass, field-glass, and telescope.

History of Astronomy
By George Forbes, M.A., F.R.S., M.Inst. C.E.
Formerly Professor of Natural Philosophy, Anderson's College, Glasgow
16mo, Adequately Illustrated Net 75 cents. (By mail, 85 cents)
No. 1. A History of the Sciences Series
The author traces the evolution of intellectual thought in the progress of astronomical discovery, recognizing the various points of view in the different ages, giving due credit even to the ancients. It has been necessary to curtail many parts of the history, to lay before the reader in unlimited space enough about each age to illustrate its tone and spirit, the ideals of the workers, the gradual addition of new points of view and of new means of investigation.
The Volume is divided as follows:
The Geometrical Period—The Dynamical Period— Observation. The Physical Period
The Solar System
A Study of Recent Observations
By Prof. Charles Lane Poor
Professor of Astronomy in Columbia University
8vo, With Frontispiece in Photogravure, 6 Plates and 32 Cuts and Figures. No. 18, Science Series, Net, $2.00
(By mail, $2.20)
The subject is presented in untechnical language and without the use of mathematics. Professor Poor shows by what steps the precise knowledge of to-day has been reached and explains the marvellous results of modern methods and modern observations.
By William Tyler Olcott
Excellently arranged, and copiously illustrated, these little manuals—real field-books—should prove valuable for all who want to become familiar with the stars
A Field Book of the Stars
16mo, With Fifty Diagrams, $1,00 net (By mail, $1.10)
To facilitate the fascinating recreation of star-gazing the author has designed this field-book. All matters of a technical or theoretical nature have been omitted. Only what the reader can observe with the naked eye or with an opera-glass have been included in it. Simplicity and brevity have been aimed at, the main idea being that whatever is bulky or verbose is a hindrance rather than a help when one is engaged in the observation of the heavens.
In Starland with a Three-Inch Telescope
A Conveniently Arranged Guide for the Use of the Amateur Astronomer
16mo, With Forty Diagrams of the Constellations and Eight of the Moon, $1.00 net, (By mail, $1.10)
The raison d'etre therefore for the book is convenience and arrangement. The author has found by experience that what the student most needs when he is observing with a telescope, is a page to glance at that will serve as a guide to the object he desires to view, and which affords concise data relative to that object. The diagrams therefore direct the student's vision and the subject-matter affords the necessary information in each case.
Star Lore of the Ages
A Collection of Myths, Legends, and Facts Concerning the Constellations of the Northern Hemisphere
8vo. Fully Illustrated
Will appeal alike to those who are interested in folk-lore and those who are attracted by astronomy. In it the author has gathered together the curious myths and traditions that have attached themselves from the earliest times to different constellations and even to individual stars.
