 This manure weighed fort}' pounds per cubic foot, or 1280 pounds 

 per plot. At this rate it would furnish, per acre : n I ogen, 89.6 

 pounds ; phosphoric acid, 34.8 pounds ; and potash, 57.6 pounds. It 

 therefore supplied a comparatively small amount of these essentials, 

 and when.it is added that it was coarse and not well mixed with the 

 soil, it will not be wondered that it produced less increase than that 

 produced by manure in most of the experiments.
