Scenes from Bird Life in Plain English for Beginners. By MABEL OSGOOD WRIGHT and ELLIOTT COUES. With One Hundred and Eleven Illustrations by Louis Agassiz Fuertes. 12mo, Cloth, $1.50 _net_. This first issue of The Heart of Nature Series—_Citizen Bird_—is in every way a remarkable book. It is the story of the Bird-People told for the House-People, especially the _young_ House-People, being dedicated “To all Boys and Girls who Love Birds and Wish to Protect Them.” It is not a mere sympathetic plea for protection. It shows how Citizen Bird “works for his own living as well as ours, pays his rent and taxes, and gives free concerts daily”; is scientifically accurate in description of anatomy, dress, and habits; and is illustrated by over one hundred engravings in half tone, together with descriptive diagrams, and has a valuable index of some one hundred and fifty-four American birds. It is a question when one becomes too old to enjoy such a delightful and entertaining book. TOMMY-ANNE AND THE THREE HEARTS By MABEL OSGOOD WRIGHT. With many Illustrations by Albert D. Blashfield. 12mo, Cloth, Colored Edges, $1.50. “This book is calculated to interest children in nature, and grown folks, too, will find themselves catching the author’s enthusiasm. As for Tommy-Anne herself, she is bound to make friends wherever she is known. The more of such books as these, the better for the children. One Tommy-Anne is worth a whole shelf of the average juvenile Literature.”—_Critic._ “Her book is altogether out of the commonplace. It will be immensely entertaining to all children who have a touch of imagination, and it is instructive and attractive to older readers as well.”—_Outlook._ “The work is probably the most charming nature-book for children published this year.”—_Dial._ FIRST BOOK IN PHYSICAL GEOGRAPHY By RALPH STOCKMAN TARR, B.S., F.G.S.A., Professor of Dynamic Geology and Physical Geography at Cornell University. 12mo, Half Leather, $1.10 _net_. The striking success of Tarr’s Elementary Physical Geography in high schools has led to the preparation of this _First Book_, which is designed for use in public and private schools requiring a somewhat shorter course than is given in the Elementary Physical Geography. Its claim to attention lies in its presentation of physical geography in its modern aspect. The main emphasis is laid upon physiography, and all the features that have contributed to the rapid introduction of the earlier books are retained in simpler form.
