290 EXPERIMENT STATION EECOED. 



scribed and illustrated by the system installed at the Northwest Experiment 

 Farm at Crookston, Minn., which has been described in a bulletin of the Minne- 

 sota Station (E. S. R., 20, p. 484). 



The country kitchen, C. Barnard {Housekeeping Expt. Sta. [Conn.] Bui. 7, 

 pp_ y^). — As a means of diminishing labor and increasing comfort, the author 

 on the basis of trials which he has conducted recommends the use of denatured 

 alcohol and fireless cookers for preparing food, with a separate heater in the 

 cellar for supplying hot water. For the latter purpose a combined laundry 

 stove and water heater of the smallest size was selected and installed in the 

 cellar as nearly under the kitchen boiler as possible and connected with a flue 

 in the chimney, the heater being connected with the device connecting the water- 

 back of the kitchen range with the boiler. 



The new house cleaning, C. Barnard ( Housekeeping Expt. Sta. [Conn.] 

 Bui. 8, pp. 4). — The advantages of vacuum cleaning are pointed out and sug- 

 gestions made regarding the use of hand and power cleaners. 



The lighting- of farm houses, I. T. Osmond (Pennsylvania Sta. Bui. 103, 

 pp. 3-19, figs. S). — This is substantially a reprint of an article previously noted 

 (E. S. R., 23, p. 592), but also includes a test of an additional kerosene burner 

 which gave very satisfactory results. 



The new lamps, C. Barnard {Housekeeping Expt. Sta. [Conn.\ Bui. 0. pp. 

 y^). — From experimental studies the author concludes that denatured alcohol 

 lamps are to be recommended. 



RURAL ECONOMICS. 



The relation of capital to agriculture, JM. Whitney {Amer. Rev. of Reviews, 

 1,2 {1910), No. 3, pp. 335-337).— The purpose of this paper is to show that capi- 

 tal will invest in agriculture when the same status prevails as in the case of 

 industrial enterprises, namely, (1) when the material and processes are under- 

 stood and control is certain, and (2) when labor can be obtained and is under 

 directive control, consequently when the products of labor are certain. To ac- 

 complish the best development in agriculture, it is believed there must be an 

 organized cooperation of effort between the various agencies of agriculture, 

 capital, transportation, and State and Federal effort, while to commercialize 

 agriculture and make it a safe line of investment for capital, the soil must be 

 understood and its use determined, and an additional supply of labor must be 

 furnished which at present must be drawn from immigrant farmers. 



The conservation of natural resources in the United States, C. R. van Hisb 

 (New York, 1910, pp. XlV+JflS, lils. 16, figs. 20).— This volume contains the 

 substance of 20 lectures delivered at the University of Wisconsin dealing with 

 the conservation of the minerals, waters, forests, and soils of the United States. 

 It gives the history of the conservation movement and discusses the relations 

 of the subject to the welfare of the v,'hole population. The data are sum- 

 marized largely from the report of the National Conservation Commission 

 (E. S. R.. 21, p. 400). 



Agricultural development in the northwest of Canada, 1905 until 1909, 

 J. Mavor {Rpt. Brit. Asmc. Adv. Sci.. 1909, j)p. 209-230, dgm. 1).— This paper 

 discusses the agricultural conditions in the three prairie provinces of Manitoba, 

 Saskatchewan, and Alberta, with more particular reference to the adaptability 

 of the region to wheat culture for export purposes. 



The region comprises some 350,000,000 acres, of which it is estimated that 

 about 17,250,000 acres are annually available for wheat with a possible pro- 

 duction of 317,375,000 bushels. Of this yield about 232,250,000 bushels could 

 be exported, which is much less than the quantity of wheat annually imported
