892 EXPERIMENT STATION RECORD. 



Ruralizing electricity, J. E. Davidson {Jour. Electricity, 31 (1913), No. 16, 

 pp. 339-3 JfJf, figs. 4)- — This article deals with the more important uses of elec- 

 tricity in rural districts, principally under conditions encountered in the North- 

 western States and from the viewpoint of the central station manager. 



Harvesting" ice with central-station energy (Elect. World, 63 (1914), No. 2, 

 p. 96, figs. 3). — The successful use of central-station electrical energy at 8 cts. 

 per kilowatt hour for ice harvesting in place of a portable engine and boiler is 

 reported. The equii>ment consisted of an induction motor, countershaft, trans- 

 formers, meter, and switch. In making the application the engine connecting 

 rod was unbolted from the crank shaft and the flywheel was belted directly 

 to the motor-driven countershaft on the truck, the rest of the hoisting mecha- 

 nism remaining unchanged. 



Farm machinery laboratory manual, D. Scoates (Agricultural College, 

 Miss., 1913, pp. 4S)- — This manual contains a list of exercises for the student of 

 farm machinery. These consist of examining the different farm machines with 

 regard to manufacture, construction, and operation. 



Agricultural machines and implements, J. Hagmann (Jahreshcr. Lamlw. 

 27 (1912), pp. 466-505, figs. 29). — This article describes and illustrates a number 

 of what are considered the more recent and efficient developments in agricul- 

 tural implements and machinery, including power plows, tractors, harrows, 

 manure spreaders, drags, drills, cultivating machinery, mechanical irrigation 

 plants, hay and grain mowers and harvesters, threshing machinery, presses, 

 grain sorters, cleaners and dryers, grinding mills, dairy apparatus, power ap- 

 paratus, small belt driven machines, and lubricators. 



Solving the fuel problem for the motor truck, H. W. Slauson (Set. Amer. 

 Sup., 76 (1913), No. 1975, pp. 292-294, figs. 5).— The author deals with the 

 characteristics of kerosene as a fuel for internal combustion engines, and de- 

 scribes and illustrates several devices for carbureting kerosene fuel, especially 

 in motor truck engines. 



Some experiments with steam threshing machinery at Cawnpore, B, C. 

 Burt (Agr. Jour. India, 8 (1913), No. 4, pp. 347-354, pi. 1). — Experiments with 

 animal and internal combustion power for threshing are said to have been un- 

 satisfactory, while by the use of a small portable steam engine fairly good results 

 were obtained. The inexperience of the labor force appeared to be the greatest 

 handicap in all the experiments, but it is believed that steam threshing is now a 

 practical proposition in that locality. 



Farm, building construction, L. J. Smith (Canad. Thresherman and Farmer, 

 18 (1913), Nos. 1, pp. 10, 64, figs. 2; 2, pp. 66, 69, 70, figs. 4; 4, PP- 80, 82, 83, 

 figs. 5; 5, pp. 22, 24, 62, figs. 5). — This article presents both by drawings and 

 popular discussion the principles of construction of the various types of farm 

 buildings, with particular reference to their adaptability to the conditions of 

 the Northwest. The principal subjects dealt with are locating and laying out 

 buildings, building foundations, stone walls, framing, and roofs. 



[Farm building, planning, and construction] (Illus. Landic. Ztg., 33 (1913), 

 No. 87, pp. 779-792, figs. 46). — Special articles contained in this periodical 

 dealing with agricultural buildings are as follows : Agricultural Building Con- 

 struction, by D. Schucht (pp. 779, 780) ; Building Material, by R. Preuss (pp. 

 780, 783), which discusses the use of brick, stone, cement, and wood in the con- 

 struction of agricultural buildings; Newer Plans for Farm Buildings, by E. 

 Kiihn (pp. 783-785), which describes and gives diagrammatic illustrations of 

 more recent developments in German farm building construction ; New Swabian 

 Farm Houses, by C. Friz (pp. 785, 786) ; Farmyard Arrangement, by Thaler 

 (pp. 786, 787) ; Sanitary Stall Construction, by P. Sieck (pp. 787-789), which 

 gives descriptions and diagrammatic illustrations of recent developments in
