FIELD CROPS. 45 



Another experiment was made to discover bow best to manure the 

 oat crop without impairing the quality of the grain or the strength of 

 the straw. Superphosphate, muriate of potash, common salt, nitrate 

 of soda, and a mixture of nitrate of soda and sulphate of ammonia 

 were used as fertilizers. The grain on plats top-dressed with nitrate 

 of soda lodged worst; an addition of muriate of potash did not prevent 

 lodging, but common salt gave satisfactory results in this respect.

Attempts to grow crimson clover, E. Davenport (Illinois Sta. Bui. 46,%pp. 

 355-357). — Crimson clover does not succeed as well in Illinois as rod clover, being 

 more subject to drought and cold, especially when small. Noticeable benefits from 

 acclimation are as yet unestablished. 



New or noteworthy American grasses, VI, G. V. Nash (Torre;/ Hid.. 24 (1897), 

 No. 4, pp. 192-201). — Notes and descriptions are given of several species of Pauicum. 



Experiments with potatoes, F. W. Rane and L. Hint | New Hampshire Sta. Bui. 

 41, pp. 1-14). — Eighty varieties were tested. Results are tabulated and notes on all 

 varieties given. Muriate and sulphate of potash proved equal in value as fertilizers. 

 Corrosive sublimate treatment reduced the percentage of scabby potatoes.

 planting of the seed, the cultivation and harvesting of the crop, and the manner 

 of securing samples for analysis.
