38 EXPERIMENT STATION. [Jan. 



depending largely upon muriate as a source of potash would 

 appear, therefore, to be wise. 



Raspberries and Blackberries. — The yield of both these 

 fruits is exceedingly small, as both were seriously winter- 

 killed. This year, however, as in earlier years, the yield on 

 the sulfate of potash is much greater than on the muriate. This 

 difference in yield is undoubtedly mainly a consequence of the 

 fact that the canes produced where sulfate of potash is applied 

 are better ripened and go through the winter better than where 

 muriate is used. 



Squashes. — The variety of squashes grown, Delicious, was 

 planted on June 29, having been put in after two failures to 

 get a satisfactory start of carrots on the plots occupied. The 

 date of planting was, of course, far later than is desirable. 

 Autumn frosts, however, held off later than usual, and a mod- 

 erate crop was secured. The yield on the muriate was con- 

 siderably greater than on the sulfate. 



Corn. — Plots 15, 16, 17 and 18 were occupied by a variety 

 test of sixteen different kinds of corn, forwarded for trial by 

 the Bureau of Plant Industry of the Department of Agriculture. 

 The results for the different varieties have not yet been fully 

 worked up, and the total yields only are presented in detail. 

 On one of the pairs of plots the muriate gives a considerably 

 larger crop of grain ; on the other the crops are substantially 

 even. The muriate gives the larger yield of stover in both 

 cases. The latter result is in accordance with those which we 

 have usually obtained where these potash salts have been com- 

 pared for corn. Earlier experiments have not shown any 

 considerable difference in the value of the two salts for grain 

 production, and the results of this year, not being in agreement 

 on the two pairs of plots, cannot be regarded as especially sig- 

 nificant. They were possibly somewhat affected by the fact 

 that so large a number of varieties was included in the experi- 

 ment ; although an effort to equalize conditions was made by 

 running the rows of the different varieties across the plots, so 

 that each plot included the same quantity of each of the several 

 kinds. 



As of possible interest, it may be here stated that among the 

 different kinds grown in this experiment, which included some
