786 EXPERIMENT STATION RECORD. 



8 In. deep, showed that for this class of work the single-cylinder tractor was 

 hardly powerful enough as even on the best land it was imposible to plow at 

 top speed. It is stated that the cost of plowing per acre will vary enor- 

 mously with the land to be plowed, and the amount to be charged for interest 

 and depreciation will always be a matter of opinion, but that the cost of plow- 

 ing virgin land is reasonable and much less than that of hand digging. 



Buildings for small holdings in England and "Wales {Bd. Agr. and Fisheries 

 ILondon], Rpt. on Buildings for Small Holdings, 1913, pp. 122, pis. 37). — This 

 report describes and discusses what are considered to be the most suitable build- 

 ings and equipment for small farms from the English viewpoint. The main 

 points considered are the small holder's house, farm buildings, unusual materials 

 and methods of construction, building by-laws, and the rural laborer's cottage. 

 Appendixes to the main report deal with such subjects as particulars of houses, 

 farm buildings and fencing erected in connection with small holdings, the in- 

 crease in rent per acre attributable to the cost of erecting farm buildings of 

 brick and timber, and the creosoting of timber. 



It is concluded that as regards the cost of equipment generally some saving 

 may be effected if houses and farm buildings are erected either in pairs or 

 groups within a limited area, thus allowing reductions (1) in the quantity of 

 necessary materials and (2) in the cost of supervision; by standardizing fit- 

 tings: and by the provision of common roads and water supply. Other more 

 specific conclusions are given regarding the design and materials of construc- 

 tion of houses and farm buildings and health regulations. A number of detail 

 plans of buildings and equipment accompany the report. 



Silo building, W. D. Nicholls (Kentucky Sta. Ext. Circ. 18 (1914), pp. 24, 

 figg^ 8). — This circular gives general information regarding silos and silage and 

 the construction of stave and concrete silos. 



How to build a Gurler silo, P. M. Brandt (Missouri Sta. Circ. 67 (1914), 

 pp. 247-257, figs. 10). — This circular is mainly a reprint of a previous one on 

 the same subject (E. S. R., 25, p. 891). 



Mississippi poultiy house, D. Scoates (Mississippi Sta. Circ, 1914, Mar., 

 pp. 8, figs. 7). — The poultiy house is described and diagrammatically illustrated. 

 The essential features are as follows: (1) It has an open front, (2) is raised 



2 ft. off the ground, (3) it can be opened on all sides, and (4) it is inexpensive. 

 This poultry house "is designed especially for the Mississippi farmer, . . . 

 should not cost over $35, and where lumber can be bought very cheap, and 

 the work done by farm hands at leisure times, it can be put up much cheaper." 



Sheep-dipping tanks, B. G. L. Enslin (Agr. Jour. Union So. Africa, 7 (1914), 

 No. 3, pp. 360-371, figs. 11).— In this article are given detailed plans, specifica- 

 tions, and descriptive and other information for the construction of an improved 

 design for a circular sheep-dipping tank. TLe circular tank is recommended in 

 preference to any other form because of its cheapness of construction, economy 

 in the consumption of dipping material, and the better results obtained with 

 less labor in dipping operations because the sheep can be kept swimming the 

 full period of its immersion. The tank is supplied with a receiving yard, forc- 

 ing pen, entrance race, inslide, outslope, dripping pens, and a drying yard. The 

 maximum diameter is 6 ft., which decreases toward the bottom, and the ap- 

 proximate capacity is 505 gal. The tank itself and the outslope are built 

 of bricks laid in ordinary blue hydraulic lime mortar with the inside plastered 

 with cement mortar. 



Sewage disposal for country homes, H. W. Riley ( Cornell Reading Courses, 



3 (1914), No. 59, pp. 149-187, figs. 27).— The purpose of this pamphlet "Is to 

 suggest to persons in country homes better methods of disposing of household 

 wastes than by means of the slop-pail and the outdoor privy." Although in-
