day was larger ou the full liiiseed-meal ration than on the rations com- 

 posed largely of sorghum or beets. With sorghum at -$2 i)er ton, 

 beets at $3, linseed meal at $28, and corn meal at $24, "all the rations 

 gave profitable results." The cost of food per pound of gain was 

 slightly larger when large amounts of sorghum were fed than when 

 only a small amount was fed j but the feeding of large amounts of beets 

 reduced the cost between one fourth and one half cent per pound ot 

 gain. 



" With beets rated at $2 per tou, as tlioy sometimes are. the di tl'erence is still ,t;rc;i ter, 

 and the increase in weight made at less cost per pound th^^n is usual with the grain 

 foods ordinarily used. 



"With tlie sorghnni rated at $1 per ton, the cost of gain made during tlic first period 

 was about the same for each lot, but during the second period still somewhat greater 

 for the lot having the large amount of sorghum." 



Value of grass and exercise in the production of pork, A. A. 



Mills ( Utah 8ta. Bui. 28, lip. 8). — To test these points, 5 lots of 3 pigs 

 each were used in an experiment lasting from June 6 to October 6, 

 Lots 1 and 2 were fed in small pens, lot 1 receiving grain and lot 2 

 grain and fresh grass. Lot 3 was fed grain in a movable pen in a 

 pasture, the pen being moved three times a day. Lots 4 and 5 were 

 allowed to run loose in the same pasture, lot 4 receiving grain and lot 

 5 no grain. The grain fed consisted of ground barley, ground wheat, 

 and bran. The average results for the whole period were as follows :

"(1) Pigs allowed to roam at will over 18 acres of good pasture, .and fed all the 

 grain they would eat, made the most rajdd growth, and aj^parently made the best use 

 of food. 



" (2) Pigs fed grass ;ind gr.un in a small yard made a more rapid growth than those 

 fed grain alone, and ;ii»parently made a slightly better use of the food eaten. . . . 



" (3) Green grass ap])ears to be of greatest value as an appetizer. 



" (4) Pig.s kept on grass alone made a slow growth — so slow that it would require 2 

 seasons for maturity — making the profits exceedingly doubtful. 



" (5) Pigs kept in a movable pen on pasture ate within 7 pounds as much grain as 

 did those in a yard without grass, but did not make as good use of it. 



" (6) Exercise seems to be necessary to increase consumptiou and probably diges- 

 tion, that growth may be rauid and economical." 



Capons and caponizing, F. L. Washburn {Oregon Sta. Bui. 31, pp. 

 89-08, fiijs. 7, pi. 1). — Remarks are made on caponizing, the tools neces- 

 sary for performing the operation, the preparation of capons for market, 

 and a report on the gains in weight of 4 birds caponized at the station.
