.acre were applied, and only kainit given in the next eight years, the 

 crop was in 1890 better by nearly 6 cwt. of hay over the not 

 manured portion, in 1891 by 18 cwt. 40 lb., in 1892 by 20 cwt. SO 

 lb., in 1893 (a very dry year) by 11 cwt. 60 lb., in 1894 by 23 

 cwt. 60 lb., in 1895 By 10 cwt. 40 lb., in 1896 by 8 cwt. 40 lb., and 

 in 1897 by 11 cwt. 20 lb., in 1898 by 4 cwt. 40 lb. So you cannot 

 form any conclusions from a single year. It is clear that the Thomas 

 phosphate acted well for nine ye#rs, and potash was much required. 

 At another meadow 31 lb. of hay were cut from 1 ar (10 

 ar J- of acre) without manure ; but a similar plot, which had re 

 ceived 12 lb. of Thomas phosphate and some kainit cut 121 lb. 

 Meadows at Upper Seehof, also destitute of phosphoric acid, yielded 

 in 1894, without manure, 17.2 cwt. per acre; but with 480 lb. of 

 Thomas phosphate, given in autumn 1893 on another portion, 24.8 

 cwt. In 1895 the results were 20.8 cwt. without manure, and with 

 another 480 lb. of Thomas phosphate, given in autumn 1894, 71.6 

 cwt. of hay. At Lower Seehof, still more destitute of phosphoric 

 acid, the unmanured portion yielded in 1894 only 6 cwt. of hay 

 per acre ; but where 480 lb. of Thomas phosphate was given in 

 autumn, 1893, 18 cwt. In 1895 the unmanured part yielded 11.6 

 cwt. ; but another 480 lb. of Thomas phosphate gave 58.8 cwt.
