590 EXPERIMENT STATION RECORD. 



to provide space for hay storage autl .stable room for 40 cows is described and 

 illustrated. 



The general plan is not elaborate and is .^aid to be well adapted to prac- 

 tically any conditions where milk is produced. The construction is of hollow 

 tile with stucco on the outside and plaster inside. It is statetl, however, that 

 the same general plan may be followed with lumber. The barn is 127 ft. long 

 and 3G ft. S in. wide. The ventilating system is of the well-known King type. 

 The foundation and first floor are constructed of 1:3:5 concrete. 



The first floor is divided into three .separate parts. One section is divided 

 into box stalls for cows and calves and bull i>ens. Another section, in which 

 there are two rows of stalls with the cows facing in, is devoted to milch cows. 

 A third section contains the milking room and medicine room. 



The first floor equipment consists of iron pipe stanchions and partitions, 

 both in the stalls and in the pens. The stanchion is of the swinging chain type 

 and the stalls are 3 ft. 6 in. wide. The mangers are of galvanized iron and 

 may be raised or lowered. A litter carrier is installed to carry the manure 

 to the pit but feed is handled on truck.s. 



Conveniences for handling' the farm cow and her products ( U. S. Dept. 

 Agr., Office Kec. Spec. [Circ], 191.'f, Dec. 31, pp. 6, figs. 10). — This circular, by 

 means of discussion and diagrammatic illustrations, gives popular information 

 regarding the cow stall, calf stanchion, milk cans, milk room and cooling box, 

 water heater, and equipment for washing dairy utensils. 



Worth and uses of silos and silag-e (Quart. Rpt. Kans. Bd. Agr., 33 (1914), 

 No. 129, pp. 110-380, figs. 36). — Pi'actical information is given on the value, 

 making, and use of silage, the materials therefor, and features for the con- 

 struction of the silos most approved. 



Details of construction and cost of vitrified tile silo, A. S. Cook [New 

 Jersey Stas. Rpt. 1913, pp. 334-34i, pl>^. 5). — The details of construction of the 

 vitrified tile silo are described and illustrated and cost data given. This type 

 of silo is considered to be one of the most substantial and eflEicient of the types 

 used at present. The total cost of such a silo erected at the station, 12 ft in 

 diameter and 32 ft. high, was $603.83. 



Steam power versus electricity for filling silos (Elect. World, 6^ (191.'f), 

 No. 19, p. 914, figs. 3). — A rural community found that the daily rent, including 

 cost of energy consumption, of a 15-horsepower electric motor with trans- 

 formers mounted on a truck when used for filling silos was considerably less 

 than the expense of using a traction engine. The electrical outfit was rented 

 for $5 per day, while the actual total cost of steam-engine drive was about 

 $12.50 per day. The average energy required per ton for silo filling was said 

 to be 1.17 kilowatt hours. 



The effects of the acid of silag'e on concrete, A. S. Neale and W. S. Corsa 

 (Concrete-Cement Age, 5 (191Jf), No. 3, pp. 125). — Both experimenters claim to 

 have observed no injurious effects on the walls of concrete silos due to acids 

 in the silage. It is stated that in case any bad effects are noticed washing with 

 neat cement or coal tar dissolved in gasoline will overcome them. 



Further studies in poultry house construction, H. R. Lewis and A. L. Clark 

 (New Jersey Stas. Rpt. 1913, pp. 259-271, pis. 4, fig. 1). — This report desci'ibes 

 and diagrammatically illustrates the so-called type L poultiy house, known also 

 as the New Jersey multiple unit laying house, developed at the station, and gives 

 the results of studies of this and five other houses which are designated by the 

 letters J, K, M, R, and P, and w^ere described in a previous report (E. S. R., 30, 

 p. 389). 



Tjiie J house is of the half monitor construction with an entire glass front in 

 the peak and with the front left entirely open two feet above the ground and
