AGRICULTURAL EDUCATION. 393 



stem introduces the ide.i of trausportation of material. Considerable emphasis 

 is placed on the need of forest conservation. Then follows a discussion of 

 various forms of the simplest plants, and particularly of the economic relation 

 existing between plants and animals. 



In the study of animal life, a number of types have been introduced with a 

 view to selection of material. A final chapter treats of health and disease from 

 the standpoint of private and public hygiene. 



Concrete problems, related when possible to the daily life of the pupil, have 

 been used throughout, stated in the form of either laboratory exercises or sug- 

 gestions. At the end of each chapter is a list of books which have proved use- 

 ful either as reference reading for students or as aids to the teacher. 



A laboratory manual for the solution of problems in biology, R. W. Sharpe 

 (Neiv York, Cincinnati, and Chicago, 1911, pp. 352, figs. 86). — An attempt is 

 made to develop a series of solutions of problems in biology, primarily physi- 

 ological in their import, but with significant references to man at every op- 

 portunity. The main divisions of the subject considered are (1) the nature 

 and needs of living matter, (2) physiological processes and adaptations in 

 plants, (3) the biological interrelations of plants and animals, (4) the most 

 successful animals, insects, and their relation to man, and (5) adaptations for 

 digestion, circulation, absorption of foods, respiration and excretion. 



The manual is intended to accompany the treatise by Hunter noted above. 



Bird studies for home and school, H. C. De Groat (Buffalo, 1911, pp. 1^6, 

 pis. 60). — The pui"pose of this book is to present to teachers and to young 

 people in school and at home a series of simple lessons on 60 common birds, the 

 most of which may be seen in parks or woods, in city or country. 



The Babcock milk test in schools (Penn. State Col. Bill. 5 {1911). No. 5, 

 pp. 18, figs. 5). — This lesson has been prepared primarily to furnish suggestions 

 to teachers in secondary schools. It presents the principles involved as well as 

 the practice or mere mechanical operation. 



Farm mechanics and drawing syllabus for secondary schools, 1911 

 ([2V^. Y.] Ed. Dept. Bui. 500, 1911, pp. 32, pis. iO).— This syllabus is designed to 

 outline and direct the work that has been indicated as "mechanical drawing" 

 and "cari^entry and joinei'y," in the first high school year of the vocational 

 course in agriculture. It takes up, besides farm mechanics and mechanical 

 drawing, forge work, gasoline engines, farm implements, equipment for draw- 

 ing and shopwork, and text and reference books and other publications. 



Silage and silo construction, C. H. Hinman {Agr. Ed. [Koms. Agr. Col.], 2 

 (1910), No. .'f, pp. 72, figs. 18). — A summary of available data on the place of 

 silage in farm economy, the chemistry of silage and its effects on digestion, 

 feeding silage to dairy cows, fattening cattle, sheep, horses, swine, and poultry, 

 the ensilage of alfalfa, clover, cowpeas, and sorghums, handling corn for silage, 

 and silo construction. 



Road locating and building simplified, C. E. Brandt (Cuniherland, Md., 

 [1908], pp. 106, p?s. 6, figs. 13). — The subject of road location and construction 

 is presented in this book in a very elementary way by means of questions and 

 answers. 



Gardens and their meaning, Dora Williams (Boston, New York, Chicago, 

 and London, [1911], pp. IX+235, figs. SJ/). — The aim of this volume is to show 

 the importance of science in the use of the spade and hoe, and to urge that 

 a garden for education may be in s])irit a corner of the great world. Consid- 

 eration is given to the location, soil, foes, and friends of the garden, and 

 specific directions are furnished for growing beans, beets, cabbage, carrots,
