192 EXPERIMENT STATION RECORD. 



Science in thrashing, C. F. Conner (St. Joseph. Midi.: The Threshermen's 

 Rerieiv Co., 1906, pp. 17 i, figs. 20). — In this work the author treats of the 

 operation, management, and care of thrasliing machinery. In the first portion 

 of the book the various parts of the thrasher are described and their functions 

 explained. Numerous practical suggestions as to adjustments and management 

 are given. 



In part 2 traction and portable engines are considered, some thermodynamic 

 theory being included, together with explanations of the action and advice as to 

 the care of various engine and boiler appliances. 



Eefrigerating apparatus, H. Pillaud (Rev. Hort. [Paris], 78 (1906). Xo. 15, 

 pp. 355-358). — In this article is noted the increasing application of cold storage 

 for the preservation of fruits and vegetables as well as l>ulbs and flowers. 

 Various machines exhibited at the last agricultural show at Paris are described. 

 Some of these machines are intended for hand power, the capacity being about 

 1,300 gm. of ice per liour. The various refrigerating mediums used in the 

 machines exhibited were ammonia, carbonic acid, sulphur dioxid, and methy- 

 lated chlorin. 



EURAL ECONOMICS. 



How to choose a farm, T. F. Hunt (Xeic York: The MacmiUan Co., 1906, 

 pp. XVIII -\-Jtl2, figs. 133). — "In this book the attempt has been made to state 

 the principles concerned in the selection of a farm, and then to apply these prin- 

 ciples to a discussion of the different regions of the Western Continent." 



The author regards farming as a business, and treats the selection, arrange- 

 ment, and management of a farm from the standpoint of making a profit. To 

 this end fertility of soil, topography, nearness of location to market, and trans- 

 portation facilities for the products of the farm are important factors in select- 

 ing farm property. " The local market is often of considerable advantage for 

 the sale of the minor products of the farm, even when the major products are 

 shipped to a distant market." 



The United States is divided by the author into geographical divisions which 

 practically conform in nature of soil, climate, and suitability of crops. Methods 

 of cultivation adapted to each region are given, as well as plans and illustrations 

 of typical farms in tliese different sections, in the outlying possessions of the 

 United States, and in other countries in North and Soutli America. 



An appendix contains information about securing title to public lands in the 

 United States and Canada, various agricultviral statistics, and an extended 

 bibliography. 



The marketing of Irish produce (Dept. Agr. and Tech. Instr. Ireland Jour., 

 6 {1906), Xo. .'/. pp. 662-675). — Based upon information secured from a large 

 number of wholesale buyers of Irish agricultural produce, attention is called 

 to the defects in present methods of grading and packing eggs, cranuned poultry, 

 and fruits. Suggestions are made to Irish producers and shii)pers for improv- 

 ing present methods of marketing these and similar goods with a view to more 

 successfully meeting foreign competition in London and other British markets. 



The economic future of the negro — the factor of white competition, 

 W. E. B. Dubois and A. II. Stone (Piihx. Aiiier. Ecoii. Assoc.. 3. scr.. 7 (1906), 

 Xo. 1, pp. 219-2'.).'i). — This is the subject of 2 papers read at the eighteenth 

 annual meeting of the American Economic Association held at Baltimore, Md., 

 December 27-29, 1905. 



Statistics are given which show that white farm laborers and particularly 

 Italian immigrants are slowly displacing the colored race in the South along 

 the line of agricultural pursuits. It is believed, nevertheless, that " the home 

 of the masses of the [colored] race must remain in the Southern States, and that 

 their destiny must be worked out upon the soil." Better educational and agri-
