plats 4, 5, 7, 8, 9, and 10; 50 lbs. per acre of potash to plat 7; and 20 

 lbs. of nitrogen per acre to plat 9, and 17.2 lbs to plat 10. Plat 1 

 received no direct manuring; the sheep grazing on it, however, were 

 fed jf lb. per head daily of decorticated cotton-seed cake. About 6 cwt. 

 per acre of ground cotton-seed cake was applied to subplat 1. At the 

 end of 3 years the pastured area of plat 1 will have received about the 

 same amount of nitrogen in the form of manorial residue as was added 

 in the form of crushed cake to the subplat. Plat 6 was not fertilized 

 and served as a control. 



Beginning June 27, 1897, 8 crossbred sheep were pastured for 1G 

 weeks on each of the plats. In 1898 the sheep were turned into pas- 

 ture May 10. Six sheep were placed on plat G; 8 on plats 2, 1, 5. 7, 8, 

 9, and 10, and 10 on plats 1 and 3. Six weeks later 1 more sheep was 

 added to plats 1 and 7 and 2 more to plats 3, 9, and 10. The grazing 

 season terminated October 3. The sheep pastured were slaughtered 

 and the weight of carcass and percentage of mutton determined. 



The average results of the tests, which are discussed in detail, are 

 shown in the following table, which gives the percentage of increase of 

 hay and mutton produced on the different plats as compared with plat 

 6 taken as a unit. The average live weight, the average dressed weight, 

 and percentage of mutton of the lots pastured on the different plats 

 are also shown.

Some experiments on the fattening value of certain foods 

 gathered by pigs, R. L. Bennett (ArJea?i8aa 8ta. Bui. 54, pp. 83-80). — 

 The value of Spanish peanuts, chufas, and soy beans for pigs was 

 tested. These crops were grown on sandy loam cotton soil, producing 

 on an average 30 bushels of corn to the acre. The pigs were confined 

 with movable fence on small areas of each crop. For purposes of com- 

 parison, one lot of pigs was fed corn in the ear. The test was made with 

 2 lots of 4 pigs, and 2 lots ot 3 pigs. At the time of feeding the soy bean
