plans which have been put forward for the housing of agricultural laborers in

Cottage building in rural districts, T. W. Pottee {Jour. Roy. Sanit. Inst., 

 36 (1915), No. 1, pp. 38-U)- — The author expresses his views regarding the 

 housing requirements in rural districts, which he states have been developed 

 from 25 years' experience, chiefly on large estates. 



Dampness in houses, its cause and remedy, M. Metzgeb (Deut. Landw. 

 rresse, 41 (19U), Nos. 98, pp. 1015, 1016; 100, p. 1032).— This article draws

ETTRAL ECONOMICS. 



The resources of "United States and their relation to opportunity, R. M. 

 Keib (Ann. Amer. Acad. Polit. and 80c. 8ci., 59 {1915), No. 148, pp. 1-28, figs. 

 36). — The author points out that the natural resources as related to popula- 

 tion are high in the United States compared with other countries, but that if the 

 resources do not increase as rapidly as the population the opportunities decrease 

 accordingly. He claims that up to the year 1892 the exports from the United 

 States were chiefly farm products. Since that time the percentage of agricul- 

 tural exports to the total has rapidly declined, while manufactured goods ready 

 for consumption have comprised a larger and larger proportion, and one which 

 is increasing more rapidly than the increase in population. With a correspond- 

 ing falling off in farm exports it follows that greater numbers of men are 

 working in factories. He believes that the country should, therefore, pay more 

 attention to conserving the wealth it has, and should make increased efforts 

 to gain foreign trade. He also advises that the United States seek to sell 

 manufactured goods and keep more raw materials at home. 



The open door to independence, T. E. Hill (Chicago: Hill Standard Book 

 Co., 1915, pp. 448, pi. 1, figs. 413). — This book describes the natural and agri-

 to engage in agriculture. 



Farms for sale or rent in New York, C. W. Labmon (N. T. Dept. Agr. Bui. 

 61 (1915), pp. 641-974, pis. ^9).— This bulletin lists the farms for sale or for 

 rent in New York, and briefly describes them. 



Farm land for sale in West Virginia (W. Va. Dept. Agr. Bui. 2 (1915), pp. 

 117, figs. 15). — This publication lists and describes the farms for sale in West 

 Virginia. 



The eflB.ciency movement in its relation to agriculture, W, J. Spillman 

 (Ann. Amer. Acad. Polit. and 80c. 8ci., 59 (1915), No. I48, pp. 65-76).— The 

 author points out a number of typical instances where an analysis of a farmer's 

 business has shown wherein lay the weakness in his system of management. 



Diversified agriculture and the relation of the banker to the farmer, B. 

 Knapp (17. 8. Dept. Agr., Off. Sec. Giro. 50 (1915), pp. 15).— In this address, 

 delivered to several State bankers' associations and the Southern Commercial Con- 

 gress, the author points out that a system of agriculture for any given community 

 ought to be self-supporting and to have sufllcient diversification so that its in- 

 terests are not jeopardized by mishaps to one crop. To bring this about he 

 suggests the establishment of local cash markets for locally grown produce, and 

 that the credit system should be so changed that the farmer would adopt a plan
