490 EXPERIMENT STATION EECORD. 



the electricity is put. The water wheel used is a 2-ft., Pel ton of special design, 

 and works under an effective head of 75 ft., while the static head is SO ft. The 

 total cost of erecting the plant, including fixtures, etc., was .$1,500, and it is 

 cstiniated that the value of the power derived is about $700 a year. 



Transportable electric motors, Teott {Maschincn Ztg., 6 (1908), No. 21, 

 pp. 2//7, 2.'f8, figs. Jf). — There is noted and illustrated a new electric motor suit- 

 able for general power use on the farm. It is from 3 to 5 horsepower and 

 constructed with special reference to easy transportation. It may be operated 

 on either direct or alternating current and also on single-phase current. 



[Test of an oil traction motor] (Impl. and Mach. Rev., SJf (1908), No. 404, 

 pp. 9G7, 968, figs. 2). — There is described and illusti-ated a motor, operating 

 on paraffin, which was awarded the highest prize at a plowing match of the 

 Boston (Eng.) Agricultural Society. The results of the operation of the motor 

 when drawing a plow and also when operating a threshing machine are given. 



Reports on agricultural machinery (Jahrl). Dcut. Landw. Gcsell., 23 (1908), 

 No. 3, pp. oi)6~590, fifjx. 27). — I'nder the head of fodder-making machines there 

 is described a new straw-cutting machine of large capacity, which may be run 

 separately or in connection with the steam thresher. Attached to the blades is 

 a wing device which lifts the cut straw and at the samfe time blows it out of 

 the machine. The wings extend beyond the knife edges and are, so adjusted 

 that the knives have a clear, unobstructed space. 



Under the head of new agricultural devices there are briefly described and 

 illustrated the following : Friction hoist for power machines ; ridge drill with 

 various changing gears ; water and plunger pump ; earth anchor for holding 

 fence posts, etc.; cylindrical harrow; baud for tying sheaths; potato-sorting 

 machine; turnip-grinding machine; feeding lattice with cattle rings; beef smoke- 

 house; transportable smoke-oven; gas producer plant adapted to private houses 

 and small farms iising from 5 to 30 lights ; harvester with attachment for raising 

 the grain to the binder; and disengaging apparatus for harrows. 



Miscellaneous implements exhibited at Newcastle, 1908 {Jour. Roy. Agr. 

 kiOc. England, 69 (1908), pp. 182-188). — A large number of implements were 

 exhibited at the 190S show of the Royal Agricultural Society of .England, these 

 including gristmills, oil motors, traction engines, pumps, cream separators, etc. 



A silver medal was awarded to a lamp pump first exhibited in 1907 and subse- 

 quently improved. This pump is of the pulsometer type, and for heads of less 

 than 50 ft. is operated on a vacuum ])roduced by condensing steam at atmos- 

 pheric pressure. For higher heads the steam is supplied at a higher pressure. 

 The steam is generated in a small boiler heated by an ordinary paraffin lamp. 

 The improvements included a new condenser arrangement which enables the 

 pump to prime itself and to work more efficiently on a long suction, and a 

 method of insuring a proper action of the water cushion at the bottom of the 

 pump. 



An effective lime spreader, F. E. Lee (Jour. Dept. Agr. Victoria, 6 {1908), 

 No. 9, pp. 528, 529, figs. 2). — This article describes a machine of simple construc- 

 tion which can be drawn by one horse. The axle is geared to a shaft carrying 

 22 cog wheels, operating small square-linked iron pulley chains 6 in. apart, 

 which pass through the box containing the powdered lime. As the machine 

 moves foi'ward the lime is drawn out by the links and is claimed to be uniformly 

 distributed on the land. 



A combined tractor irrigating machine {Engineer [London'], 107 {1909), 

 No. 2788, p. 590, fig. 1). — There is here given a brief description of a traction 

 machine operated on petrol and provided with a turbine pump carried on an 

 extension of the frame at the rear. This combination is intended especially to 

 serve the needs of sugar planters, as it can be taken to any part of the field
