1, Timothy and Glover {Sulfate v. 3Iuriate of Potash). 

 Mixed timothy and clover occupied, two plots which were 

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

 sulfate of potash plot was 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 rowen 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 l^etter upon sulfate than upon muriate 

 of potash. The experiment of the present 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 growth of mixed 

 white and alsike clover, ^vith some sorrel and weeds, was 

 ploughed in a few days before planting the cabbages. The 

 variety of cabbage groAvn Avas the All Seasons, fi'om
