“One of the most delightful semi-scientific books, which everyone enjoys reading and at once wishes to own. Such works present science in the most fascinating and enticing way, and from a cursory glance at paragraphs the reader is insensibly led on to chapters and thence to a thorough reading from cover to cover.... The work is especially well adapted for school purposes in connection with the study of elementary natural science, to which modern authorities are united in giving an early and important place in the school curriculum.”—_The Journal of Education._ =HUTCHINSON.=—=The Story of the Hills.= A Book about Mountains for General Readers and Supplementary Reading in Schools. By H. N. HUTCHINSON, author of “The Autobiography of the Earth,” etc. Illustrated. $1.50. “A book that has long been needed, one that gives a clear account of the geological formation of mountains, and their various methods of origin, in language so clear and untechnical that it will not confuse even the most unscientific.”—_Boston Evening Transcript._ “It is as interesting as a story, and full of the most instructive information, which is given in a style that everyone can comprehend....”—_Journal of Education._ =INGERSOLL.=—=Wild Neighbors.= A Book about Animals. By ERNEST INGERSOLL. Illustrated. 16mo, Cloth. _In Press._ =JAPP= (A. H.).—=Hours in My Garden=, and Other Nature-Sketches. With 138 Illustrations, $1.75. “It is not a book to be described, but to be read in the spirit in which it is written—carefully and lovingly.”—_Mail and Express._ “It is a book to be read and enjoyed by both young and old.”—_Public Opinion._ =POTTS= (W.).—=From a New England Hillside.= Notes from Underledge. By WILLIAM POTTS. _Macmillan’s Miniature Series._ 18mo, 75 cents. “But the attraction of Mr. Potts’ book is not merely in its record of the natural year. He has been building a house, and we have the humors and the satisfactions, and hopes deferred, that usually attend that business. He has been digging a well, and the truth which he has found at the bottom of that he has duly set forth.... Then, too, his village is Farmington, Conn., and there Miss Porter has her famous schools, and her young ladies flit across his page and lend their brightness to the scene. And, moreover, he sometimes comes back to the city, and he writes pleasantly of his New York club, the Century. Last, but not least, there are lucubrations on a great many personal and social topics, in which the touch is light and graceful and the philosophy is sound and sweet.”—_Brooklyn Standard-Union._ =WEED.=—=Life Histories of American Insects.= By Prof. CLARENCE M. WEED, New Hampshire College of Agriculture and Mechanical Arts. Fully Illustrated. Cloth. _In Press._ “_AN IDEAL BOOK ON NATURE STUDY._” CITIZEN BIRD
