1. Timothy and Clover (^Sulfate v. Muriate of Potash). 

 Mixed timothy and clover occupied two plots which w^ere 

 seeded in July, 1901. The proportion of clover on the 

 sulfate of potash plot w'as distinctly greater than on the 

 other. The variety of clover was the alsike. The yields 

 are shown in the table : —

It will be seen that there is no considerable difference in 

 the amount of hay yielded by the two potash salts. The 

 first crop, indeed, in which of course timothy was relatively 

 abundant, was practically equal upon the two. There is 

 more difference in the rowxn crops, which is without doubt 

 a consequence of the better growth of the clover (which 

 furnishes most of the rowen) on the sulfate of potash. Our 

 results, then, are confirmatory of those in previous years, 

 which have tended to show that, especially in cool and wet 

 seasons, clover does better upon sulfate than ui)on muriate 

 of potash. The experiment of the })resont season upon 

 another of our fields (Field G), to be reported later, is 

 also strikingly confirmatory of this general principle. 



2. Cabbages. 

 Cabbages occupied two plots (17 and 18) on which clover 

 was grown last year ; and a considerable growtli of mixed 

 white and alsike clover, with some sorrel and Aveeds, was 

 ploughed in a few days before planting the cabbages. The 

 variety of cabbage grown was the All Seasons, from 

 Gregory & Son, INIarblehead. The seed was planted in hills 

 3 by 21/^ feet apart on June IC). A very heavy shower 

 interru})ted the work, and so packed the soil on the nuu'iate
