best to publish the results. The lateness of planting, caused by ill- 

 ness, no doubt in part accounts for the poorness of the crop. Obser- 

 vations and measurements taken at different times throughout the 

 growing season resulted in ranking the plots from an early date in 

 the order in which the harvest showed them to stand. 



Summary of Weather Observations, Mat 14 to Sept. 1, 1891. 



*110 riays. 



The light rainfall in May and June is the most striking peculiarity 

 brought out by these figures, and this feature of the season acting in 

 conjunction with the low temperature several times occurring in May 

 must have injured the crop somewhat, though less seriously than had 

 the dry weather occurred later. 



ANALYSIS OF MANURE USED. 



Moisture at 100° C, 



Phosphoric acid. 



Potassium oxide. 



Nitrogen, 



Insoluble matter, 

 This manure weighed 31 pounds per cubic foot, and at the rate 

 used would supply per acre nitrogen, 64.9 pounds; phosphoric acid 

 43.6 pounds and potash 55.6 pounds. It thus appears to have been 

 a light and comparatively poor manure supplying considerably less 

 potash and phosphoric acid, but more nitrogen than "complete" 

 fertilizer. 



In spite of this evident inferiority it apparently caused a larger 

 increase in crop than the fertilizer.
