subsequently subdivided, like the latter, into two equal 



parts. One part was treated broadcast with a mixture of 



air-slaked lime and of bisulphide of 



carbon, and the other one with that of 



air-slaked lime and of carbolic acid, in 



the same way, as far as relative portions 



and total amount are concerned, before 



planting. 



The potatoes were planted on all the 

 plats May 7 ; they appeared pretty 

 uniform above ground May 27. The 

 general treatment of the crop during the 

 entire time was the same on all plats, 

 and closely corresponded to the course 

 pursued in preceding years. The vines 

 began to change their color August 17, 

 and were all dead August 31. The 

 change seemed to be a natural one ; no 

 indications of blight could be discovered 

 on the leaves ; the extreme wetness of 

 the season seemed to favor the continu- 

 ation of the growing period. The crop 

 on all the plats was harvested Septem- 

 ber 7. An examination of the entire 

 crop, when spread out over the field, 

 showed no marked difference in any 

 particular part of the various plats. The 

 potatoes were of a fair size, but seriously 

 sufiering from scab and rot. 



Plat 1 yielded 1,080 pounds of pota- 

 toes ; plat 2, 876 pounds, and plat 3, 

 976 pounds, of all sizes. Fifteen bushels 

 of scabby potatoes, nearly one-third of 

 the entire crop, were collected before 

 the crop was removed from the field. 



Although the results of the year are 

 discouraging, the experiment will be repeated, with some 

 modification, when a more favorable season may assist in the 

 work.
