Spraying jim times with Bordeaux mixture vs. no spraijlng. — 



Hubbs Bros., Madison Co. Soil, sandy witli a sandy subsoil, 



dressed with 15 loads of stable manure per acre. This crop ^vas 



grown by the improved methods except that a part was left 



unsprayed.

 the sprayed portion of the field yielded at the rate of 283.8 bushels— a 

 gain of 36.6 bushels apparently due to the spraying*. 



The Ilubbs Bros, write as follows : " Having heard a rejn-esenta-

Results : The hill area yielded at the rate of 122 1-2 bushels per acre,

 that the very frequent and persistent stirring" by hand was not product- 

 ive of g-ood results.
