_Edited by John W. Ritchie_ TREES, STARS _and_ BIRDS A BOOK OF OUTDOOR SCIENCE By EDWIN LINCOLN MOSELEY _Head of the Science Department, State Normal College of Northwestern Ohio_ The usefulness of nature study in the schools has been seriously limited by the lack of a suitable textbook. It is to meet this need that _Trees, Stars, and Birds_ is issued. The author is one of the most successful teachers of outdoor science in this country. He believes in field excursions, and his text is designed to help teachers and pupils in the inquiries that they will make for themselves. The text deals with three phases of outdoor science that have a perennial interest, and it will make the benefit of the author's long and successful experience available to younger teachers. The first section deals with trees, and the discussion of maples is typical: the student is reminded that he has eaten maple sugar; there is an interesting account of its production; the fact is brought out that the sugar is really made in the leaves. The stars and planets that all should know are told about simply and clearly. The birds commonly met with are considered, and their habits of feeding and nesting are described. Pertinent questions are scattered throughout each section. The book is illustrated with 167 photographs, 69 drawings, 9 star maps, and with 16 color plates of 58 birds, from paintings by Louis Agassiz Fuertes. It is well adapted for use in junior high schools, yet the presentation is simple enough for pupils in the sixth grade. _Cloth. viii + 404 + xvi pages.

Ritchie_ SCIENCE _for_ BEGINNERS _By_ DELOS FALL _Professor of Chemistry, Albion College_ To supply the need for a course that will give the preparatory training which any scientific study demands, SCIENCE FOR BEGINNERS by Professor Delos Fall was made. The aim in this text is to win the interest of pupils, to give them conceptions of nature that are fundamental, and above all to ground them in the method of science. The subject matter has to do with the earth sciences, and principally with physics and chemistry. In the development of each topic, every advantage that the pupils' experience and interest may afford is utilized. Exercises or experiments are interspersed throughout the work, and for these only the simplest materials are required. The studies are carried to those connecting principles which permit the organization of knowledge. The book is illustrated with a number of excellent photographs and over 200 drawings of more than usual merit.
