complete and uniform distribution of sunlight, type house L being excep- 

 tionally well planned with reference to the total amount of sunlight secured 

 on the floor at one time, and also with reference to the large area of floor space 

 which was bathed in sunlight sometime during the day." 



A consideration of relative total efficiency of the types " shows that the 

 houses stand in the following order, L, II, J, P, INI, and K ; that is, type house 

 L, considered from the standpoint of low cost, warmth in winter, coolness in 

 summer, and dryness, was the most efficient type. Type houses M and K, 

 the former of hollow-tile construction and the latter elevated, with an entire 

 glass front, are not desirable types." 



The third part of the bulletin discusses in considerable detail a number 

 of different standard types of poultry liouses which have been tested out at 

 the station. A bibliography is appended. 



RUEAL ECONOMICS. 



Beport of committee appointed by the Secretary of Agriculture to consider 

 the subject of farm organization as one of the di'/isions of research work of 

 the proposed Bureau of Farm Management and Farm Economics (U. S. Dcpt. 

 Affr., Off. tiec. Circ. 135 (1919), pp. 12. — This report represents the conference of 

 April 17-19, 1919, as outlining studies for a proposed division of farm organiza- 

 tion in the proposed Bureau of Farm Management to include types of farming 

 covering determination of enterprises ; balance or combination of enterprises ; 

 size of business, farm plan or layout; effective use of labor and equipment; 

 intensity of production ; and business methods. It states briefly the value of 

 survey, cost accounting, observation, geographic, historical, statistical, and 

 experimental metliods of studying farm organization. Recommendations as to 

 procedure in bringing about cooperation between the Office of Farm Manage- 

 ment and agricultural colleges and experiment stations, and suggestions for a 

 memorandum of agreement that should be drawn up between the U. S. De- 

 partment of Agriculture and the colleges or stations are made. 



Farm types in Nebraska, as determined by climatic, soil, and economic 

 factors, 11. K. Spafford (Nebraska Sta. Research Bui. 15 (1919), pp. 5-85. figs. 

 38). — This bulletin treats of the agricultural areas of Nebraska, as determined 

 by climatic, soil, and economic factors, the emphasis being placed upon the kin<l 

 of farm crops grown and Ihoir yields. The data were principally derived from 

 the Thirteenth Census and cover the crop year 1909. The effect of heat and 

 other factors upon the acreage of crops treated as annuals, the size of the 

 farm in relation to rainfall, and otJier factors in the Great Plains are dis- 

 cus.sed in detail. Farm types are groupetl and farm-type areas described and 

 located. Acreage, yield, and value of crops, crop indexes, and live-stock and 

 miscellaneous statistics are given. 



Dairying and general farming for the timbered section, A. J. McGuire 

 (Minnesota Sta., Spec. Rpt. Grand Rapids Substa. 1904-191^^ pp. 37, figs. 19). — 

 This report is a resum§ of results of work at the substation at Grand Rapids, 

 Minn., from 1904 to 1914, to find the most practical and profitable system of 

 farming for the timbered section of northern :Minnesota, and especially to 

 demonstrate making a living fi-om 20 acres or less under cultivation while 

 clearing and developing more land to a point where the farm can be made most 

 profitable. Some of the cimclusions arrived at are as follows: 



Dairying, with potatoes as a cash field crop, is believed to be the most profit- 

 able system of farming for the average farm of the timbered section of northern 

 Minnesota. A production of 200 lbs. of butter fat a year is necessary for a 

 cow to be profitable from a business standpoint, even on moderately priced land.
