Soil Test with Onions. Amherst. 

 This experiment occupied a field which has been employed 

 in work of this kind for ten years, the several plots having 

 been every year manured alike, as described under the " Soil 

 test with corn." The previous crops in the order of rotation 

 have been : potatoes, corn, soy beans, oats, grass and clover, 

 grass and clover, cabbages and ruta-baga turnips, potatoes 

 and onions. The land was ploughed in the fall of 1898 and 

 reploughed early this past spring. Fertilizers were em- 

 ployed this year in the same quantities as last, viz., nitrate 

 of soda at the rate of 320 pounds ; dissolved bone-black, 640 

 pounds ; and muriate of potash, 320 pounds, per acre. These 

 fertilizers are each used upon one plot singly, in pairs, and 

 upon one plot all three together. The west half of each 

 plot was limed, as has been stated, at the rate of 1 ton per 

 acre.
