 matic illustrations of six types of barns are included. 



Bams for work animals, B. Youngblood {Texas Sta. Bui. 210 {1917), pp. 

 3-28, figs. 18). — It is stated that "satisfactory barns, large enough only for 

 the work stock and a year's supply of feeding stuff, can be constructed in Texas 

 at a cost of from $25 to §550 per animal. If as much as from $100 to $300 per 

 animal is put into the barn, a proportionate amount of extra storage space 

 for additional hay, grain, seeds, and so forth, may be had at less additional 

 cost than would be the case if a separate storage building were constructed." 



Suggestive plans are given which demonstrate principles applicable to Texas 

 conditions. These are to be modified to meet local conditions. " The plans 

 given begin with the cheapest possible, and end with a moderate-priced struc- 

 ture. The chief difference is in the size, convenience in feeding, and the 

 amount of extra storage space supplied. No general-purpose barn plans are 

 given, for the reason that it is better under southern conditions to have special- 

 purpose buildings, separate and apart." 



Bills of material and lumber necessary for the construction of various sized 

 barns for work animals are also included. 



Measuring silage and capacity of silos, L. W. Chase {Nebraslca Sta. Circ. 1 

 (1917), pp. 14, flyfi- 5). — As the result of silage weighing experiments a new 

 table of weights of silage is proposed for determining the capacities of silos, the 

 rule for which assumes that silage settles 10 per cent after filling ceases. A 

 comparison of the new weights with those established by King at the Wisconsin 

 Station shows that the new weights are from 11.5 to 13 per cent less than the 

 Wisconsin weights. The new table of weights was found to be very nearly cor- 

 rect on the basis of actual weighing, being if anything a fraction too large. 



The proposed weights are given in the following table : 



Weight of silage per cubic loot. 



Tables are also given showing the relative capacities of silos and estimated 

 tonnage of silage by volume, together with information regarding the determina- 

 tion of silo capacities. The experimental results on which the tables are based 

 are included. 



Poultry houses and poultry equipment for Texas, R. N. Hakvey, J. C. 

 Olsen, F. W. Kazmeiee, and T. J. Conway {Texas Sta. Bui. 207 {1917), pp. 28, 

 figs. 17). — Plans of poultry houses and equipment are given and discussed, 

 which, it is stated, with modifications of structure to fulfill needs imposed by 

 climatic conditions may be used satisfactorily in almost any locality.
