phosphoric acid plot, and the high tonnage of sugar from the stable manure plot with a 

 correspondingly low percentage of sugar, which brings the final yield of sugar per acre 

 even below that of the mixed mineral plot No. 7 and the complete fertilizer plot No. 8. 

 The experiment was -planned with a view to determining the effect of fertilizers upon 

 tho sugar content of the product, as well as on the tonnage of the crop. So far as the 

 percentage of sugar from the single elements is concerned, the greater percentage front 

 the application of nitrate of soda as compared with the phosphoric acid and potash plots, 

 is something of a surprise. The lower yield of the phosphoric acid plot as compared wil h 

 the relative yields of the three double element plots is somewhat incompatible, although 

 the percentage of sugar from the double element plot harmonizes with that of the single 

 element plots, except the results from plot G where nitrogen and potash are combine I 

 in the fertilizer, and the yield of sugar is lower than from either of the single elemenl 

 plots. The effect of the stable manure in giving a comparatively low percentage of sugar, 

 and an excessively high yield in tonnage of beets is in accord with other experiments of 

 this nature. The general conclusion is that for the best results no single element or two 

 element fertilizer will do as well as our complete fertilizers, and that stable manure 

 increases the tonnage but does not increase the total number of pounds of sugar in ■>. 

 similar proportion.
