cultural practice in tropical countries. Three chapters are contributed by A. 

 Linton on atmosphere and climate in relation to agriculture, the soil and its 

 properties, and the cultivation of the soil. R. Lang-Anderson has three chapters 

 on irrigation and drainage implements, and land reclamation. The remaining 

 two chapters discuss cultivating and harvesting implements and manures. 



Economical farm and dairy management, A. Ducloux {Econoinie Menagere 

 Agricole et Laitcric. Paris, HJOS, pp. 332, flgs. 1S2). — This volume is designed

 similar questions. The second part has to do with dairying and pork raising, 

 and the third with milk, butter, and cheese. The fourth deals with poultry 

 raising, and the fifth with gardening. 



The physical properties of soils, A. C. McCall {New York and London, 

 1909, pp. y 111+ 102, pis. 3, figs. 32).— A laboratory manual for the use of 

 students in soil physics. It covers the range of experiments usually taught 

 in such courses and includes rules for the use of the chromic-acid method of 

 determining organic matter in a soil, and directions for standardizing the eye- 

 piece micrometer used in the mechanical analysis of soils. 



Farm arithmetic, Jessie Field {Shenandoah, Iowa, 1909, pp. 20). — In this 

 little manual about 125 agricultural problems, intended to supplement the text- 

 book in arithmetic for pupils in the seventh and eighth grades, are grouped 

 according to subject-matter, some dealing with the farm inventory, others with

Plant breeding, G. F. Freeman {Agr. Ed. [Kans. Agr. Col.], Farmers' Inst. 

 Ser., 1 {1909), No. 2, pp. 92, figs. 21). — A prefatory note to this number indi- 

 cates as the general purpose of the series the stimulating of Kansas young peo- 

 ple to a perception of the fact that successful farming is an intellectual occupa-

 ment, including grapes, apples, pears, plums, and the small fruits, and cereal 

 breeding, including corn, wheat, and miscellaneous crops. It also includes a 

 reprint of an article by the same author on the Scientific Principles of Plant 

 Breeding. The historical development of the subject is adequately treated, and 

 directions for its practical application on the farm are clearly given. 



An elementary study of insects, T. J. Headlee {Agr. Ed. [Kans. Agr. Col.], 

 Teachers' and Pupils' Ser., 1 (1909), No. 3, pp. 52, figs. ^7). — This number con- 

 tains an illustrated description of the structure of insects, directions for col- 

 lecting and mounting specimens, and a detailed life history of the Hessian fly, 

 chinch bug, codling moth, clothes moth, and honeybee, with methods of combat- 

 ing those which are injurious. 



Insects injurious to farm crops, G. A. Dean {Agr. Ed. [Kans. Agr. Col.], 

 Farmers' Inst. Ser., 1 {1909), No. J/, pp. 91, figs. 85). — This number is devoted 

 to a study of insects and small animals injurious to farm crops and is fully
