tions, and complete lists of materials required for the construction of poultry 

 buildings, such as are now in use at the Puyallup Substation. Advice is also 

 offered concerning the selection of the site for the buildings. 



The incubator house described is 16 by 20 ft., with 9-ft. posts, and is large 

 enough to hold 6 250-egg incubators. In this house " three hatches of hen eggs 

 were made, which, with the exception of one machine on one occasion, hatched 

 an average of from 85 to 93 per cent of the fertile eggs, producing chicks of ex- 

 ceptional vigor and con.stitution, which since September and October have been 

 demonstrating their sui)eriority as layers. In one of these machines were set 

 102 turkey eggs, from which were hatched 86 turkeys, strong and vigorous." 



The brooder house is 16 by 50 ft., and contains 12 windows and faces south 

 in order to let in as much sunlight as possible. The yard is located on the 

 south side of the buildings. The colony coops are 6 by 3 ft., and will hold about 

 50 chickens from 6 to 8 weeks of age. The laying house of 140 by 12 ft. con- 

 tains 8 rooms 3 2 by 15 ft. and a feed room.

RURAL ECONOMICS. 



New views on agricultural economics, G. Borghesani (Agr. Mod., 16 (1910), 

 No. 13, pp. 170-112). — The author discusses the factors which enter into the 

 cost of production and the price of agricultural products, and calls attention 

 to some of the latest teachings of agricultural chemistry, soil bacteriology, 

 biology, and soil analysis in their bearing on the cost of production and the 

 net returns to the producer. 



If the teachings of these sciences be regarded as correct, there has been a 

 great waste of economic forces in agricultural wealth production in the past, 

 such as the use of more fertilizers than plants could assimilate and the applica- 

 tion of more capital and labor than would yield profitable returns. The teach- 

 ings of these sciences, it is believed, determine to a greater or less extent the 

 quantity of fertilizer, the degree of intensity of culture, and the amount of 

 capital and labor that can be employed to give the greatest net returns to 

 producers of agricultural forms of wealth. 



The farmer and his relation to the economics of the nation, E. J. Watson 

 (1910, pp. 23). — The great value of farm' products as the basis of economic 

 activity in providing food and clothing for mankind is pointed out in this 

 address delivered before the National Farmers' Convention, St. Louis. May 2-7, 

 1910. The economic difficulties under which Southern cotton growers dispose 

 of their crops in the United States and foreign countries are emphasized.
