and tin eqiuil amount in millet. There is a slight difference in 

 favor of the special fertilizer in the case of the grain, but an equal 

 advantage in favor of the fertilizer richer in potash in the case of 

 the stover in the corn experiment. In the case of the millet the 

 advantage is with the home mixture both in grain and straw. The 

 figures are as follows : — 



The materials in the special fertilizer cost at the rate of $13.66 

 per acre ; those in the home mixture, ^10.70. 



Two experiments have been tried for the comparison of the sul- 

 phate with the muriate as a source of the potash in fertilizer for 

 potatoes. In one experiment all the fertilizers were applied broad- 

 cast, in the other they were broadly scattered in the drill. In both 

 experiments the results were decidedly in favor of the sulphate. 

 The yields per acre were as follows : — 



Sulphate of Potash. 

 Broadcast, merchantable tubers, bs5.7 bushels; small tubers, 10 8 

 bushels. 



Drill, nicreliantable tubers, 192.5 bushels; small tubers, 13.5 bushels. 



Muriate of Potai^h. 

 Broadcast, merchantable tubers, 166.6 bushels; small tubers, 13.3 

 bushels. 



Drill, merchantable tubei's, 179.1 bushels ; small tubers, 17.0 bushels» 



In these experiments the fertilizers were used in such quantities 

 as to supply equal amounts of actual potash in each plat, and 

 together with the potash salts were used suitable amounts of 

 fertilizers supplying nitrogen and phosphoric acid, the same to each 

 plat. 



In appearance when cooked, and in eating quality, the potatoes 

 grown upon the sulphate of potash were distinctly and decidedly 

 better than were those grown upon the muriate. This statement is
