The table herewith, compiled from the more detailed figures of the 

 bulletin, <;ives estimated yield.s per acre and increase of dry matter in 

 maturing. The results are, of course, subject to the inevitable sources 

 of error of plat experiments with different varieties of plants : 



Exj)erimeuts at this and other stations last season show that much of 

 the dry matter of the corn crop is lost by harvesting before the corn is 

 mature. These results are confirmed by the figures herewith given. 

 At the time when the kernels began to glaze the largest amount of dry 

 matter per acre in these trials was 5 tons, the smallest 1.3 and the aver- 

 age about 3 tons. In the field-cured material the maximum was 5.1; 

 the minimum 2, and the average about 2.9 tons. The largest gain by 

 allowing the crop to mature was 2| tons, the smallest 2, and the aver- 

 age three fourths of a ton. The average of the dent varieties for the 

 two seasons shows a gain of nearly one fifth of the total amount by 

 allowing the plants to mature; and the greatest gam, with one excep- 

 tion, was made by those varieties.

The sugar-beet, L. Foster, M. S. A., and J. H. Shepard, M. A. — 

 "The station has completed its second season's tests of the sugar-beet, 

 and the result gives us still better evidence of its crop value to South 

 Dakota both for stock feeding and sugar making. While the crop was 

 not as great either in percent of sugar or yield of roots per acre as may 

 reasonably be expected iu more favorable seasons, or by following more
