mented material where the growth and color were strikingly better, the 

 first leaves after the cotyledons appearing sooner and growing more 

 rapidly than in the checks and in the un fermented mushroom. In case 

 of buckwheat the plants in un fermented mushroom were slightly better 

 than in checks, while the sunflower plants showed little advantage. In the 

 checks and un fermented mushroom the sunflower plants did not do well. 

 Large areas on the stem were collapsed and dead ; also dead spots ap- 

 peared on the leaves. Some of these plants later died and some of the

leaves later showed Botrytis. The sunflower plants seemed to be weak- 

 ened by the action of the freshly formed products of fermentation so 

 that they were susceptible to the attack of the Botrytis. 



In case of the radish, the plants in the baskets with un fermented 

 mushroom outgrew all the others and showed better color, those in the 

 fermented were next, all showing rich color. The checks were small, 

 puny, and yellowish on margins of leaves.
