The relative value of corn, oats, wheat, and hay in a four-course rotation 

 during 25 years, T. F. IIfnt {PeiDisijliania ,S7«. h'ltl. 1!)09, />yj. 21-26, pi. I). — 

 Tl,e data contained in this article have already been reported from somewhat 

 different standpoints (H S, R., 21, p. 220). 



A corn-oat-wheat-hay rotation was grown under 24 different fertilizer treat- 

 ments. The total average weight of corn per acre during the 2.") years was 6.062 

 lbs. valued at $29.67; of oats 2.999 lbs. at $14.49; of wheat 3,291 lbs. at $18.47; 

 and of hay 3,609 lbs. at $18.05. The grain yields were about 50 bu. of corn, .38 

 bu. of oats, and 20 bu. of wheat per acre, with a little less than 2 tons of hay 

 per acre. The average annual return from this rotation was $20.17, while the 

 estimated average annual return from a corn-corn-oat-wheat-hay rotation would 

 have been $20.45. or from a corn-coru-oat-wheat-hay-hay rotation $21.71. The 

 untreated plats yielded crops valued at $15.76 per acre, those treated only with 

 mineral fertilizers $21.13. and those treated with yard manure $22.25. 



Forage plants for western Washington, W. H. Lawrence and H. L. Blanch- 

 ARD (Washington Sta. Bui. 2, spec, ser., pp. 5-^5). — This bulletin discusses 

 forage crops and gives directions for the production in western Washington of 

 root crops, cabbage, thousand-headed kale, legumes, grains, grasses, and pota- 

 toes. A table of quantities per acre to sow of different kinds of seed is given. 



Results of cooperative experiments in agriculture, C. A. Zavitz and \V. P. 

 Gamble (Ann. Rpt. Ontario Agr. and Expt. Union, 31 (1909), pp. 13-^3). — 

 These pages report the results of experiments in which 4,856 men cooperated. 

 The principal results of these cooperative tests are stated in the following

In fertilizer tests with winter wheat, swedes and potatoes, fields fertilized 

 with cow manure produced higher yields than those fertilized with any
