The young crop was hoed June 9th. The difference in 

 the appearance of the plats was quite marked, July 24th ; 

 •the plat (No. 1) with muriate of potash had the largest 

 foliage and looked darker o-reen than the remainder ; that 

 with potash sulphate (No. 3) looked next l)est. A blight 

 on the leaves, which showed itself during the first week of 

 August, terminated prematurely the experiment ; the vines 

 upon all plats died soon after. The crop was harvested 

 August 26th, with the following results : —
