Aug. 9th. The foliage of the plots which received nitrate of 

 soda alone is now dying, not as if the tubers were maturing, but 

 rather as if from some harm or disease. In the first nitrate of 

 soda plot half of the plants are dead. 



Eesults on the foliage the same with sulphate of ammonia 

 alone as with nitrate of soda alone, as above described. {Rural 

 Aug. 9.) It will be remembered that all the plots that received 

 nitrate of soda or ammonia salts were rated in our last report, in 

 every instance, as giving the strongest and greenest growth of 

 vines. That these plants should now be dying, evidently before 

 maturity, is to us quite unaccountable. 



Phosphoric acid alone, or in combination with potash, failed 

 to do any good. It is only when nitrate of soda or ammonia salts 

 were spread on these with potash and phosphoric acid, forming a 

 complete fertilizer, that any good effects are noticed. The plants 

 fertilized with the dissolved bone black are all green. {Rural 

 Aug. 9th.) 



The potato tops on all of the unfertilized plots appear to be 

 the same in height, color and vigor ; the plants are all green. 

 {Rural Aug. 9th.) 



Potash, whether in wood ashes or as sulphate or muriate of 

 potash produces thus far, no additional growth of tops. Kainit 

 alone changes tops to a yellowish color. {Rural Aug. 9th.)
