THE WHITE MOUNTAINS. A Guide to their Interpretation. With a Map of the Mountains and Ten Illustrations. By Rev. Julius H. Ward. 12mo. Cloth, gilt top, $1.25.

Mr. Ward has spent his summer vacations in the White Mountains for several years, and has entered deeply into their life and meaning. This book is both a guide to a better knowledge of the White Hills and a souvenir of what one finds in them. "Nature," says the author, "in these retreats is very coy, and her secrets are only communicated to those who seek them. The ability to enjoy natural scenery is partly a gift, but it may be immensely increased by habits of observation."

"The author is thoroughly in love with his subject, and not less thoroughly acquainted with it. Though he disclaims intention to write a guide-book, the visitor to the White Mountains can hardly fail to profit by his picturesque descriptions, hints about paths and points of view, and abundant suggestions as to times and seasons."—New York Tribune.

THE GARDEN'S STORY; or, Pleasures and Trials of an Amateur Gardener. By George H. Ellwanger. With Head and Tail Pieces by Rhead. 12mo. Cloth, extra, $1.50.

A literary ramble amid the flowers of the garden, with practical hints upon the cultivation of plants, and gossipy comments upon the characteristics of favorite flowers.

"Mr. Ellwanger's instinct rarely errs in matters of taste. He writes out of the fullness of experimental knowledge, but his knowledge differs from that of many a trained cultivator in that his skill in garden practice is guided by a refined æsthetic sensibility, and his appreciation of what is beautiful in nature is healthy, hearty, and catholic. His record of the garden year as we have said, begins with the earliest violet, and it follows the season through until the witch-hazel is blossoming on the border of the wintry woods…. This little book can not fail to give pleasure to all who take a genuine interest in rural life."—New York Tribune.

ASTRONOMY WITH AN OPERA-GLASS. A Popular Introduction to the Study of the Starry Heavens with the Simplest of Optical Instruments. By Garrett P. Serviss. 8vo. Cloth, $1.50.

This is a unique book, quite alone in the field that it occupies. The call for a fourth edition within two years after its first publication attests its popularity. As one of its reviewers has said, "It is the most human book on the subject of the stars." It would have supplied Thomas Carlyle's want when he wrote, "Why did not somebody teach me the stars and make me at home in the starry heavens?" Interest in the geography of the heavens is increasing every year, as the discoveries of astronomers with the giant telescopes of our day push back the limits of the known universe, and this book is to those who read of such discoveries like an atlas to the student of history.

Some of the compliments that the book has received are these:

"A most interesting and even fascinating book."—Christian Union.
