cut, the first on July 3. The plants at this time had ceased 

 growth, on account of drought. Not all had blossomed, yet 

 the condition must be classed as mature. The yield was 

 seriously decreased by the dry weather. The second crop 

 was cut August 21, being somewhat mixed with annual 

 grasses, but apparently to equal degree in all plots. The 

 hay was secured in good condition, being cured mostly in 

 the cock. The table shows the fertilizer treatment and 

 the yields of the several plots : —

It is perhaps questionable whether much weight should be 

 attached to the yields at the first cutting, since full develop- 

 ment was not reached on account of drought. The rowen 

 gives a better basis for comparison. Studying these figures, 

 we find the following points bearing upon the problem on 

 which the experiment seeks to shed light : —
