The sulfur and "Bj^-product A" were applied dry and thoroughly 

 mixed with the 3 inches of top soil. The formaldehyde was so diluted 

 that it was applied at the rate of one-half gallon of solution to the square 

 foot of surface. On the first year's plots observations of a miscellaneous 

 character were taken in addition to the root-rot data. The observations 

 relating to growth are noted in the follo^ving table. They were made two 

 weeks before harvesting. The growth data are calculated on the basis of 

 the checks equalling 100, the plots being greater or less than this.
