than the same substance used in the fresh condition in 1895, 

 but the gas lime acted more powerfully in the direction of 

 increasing the weight of roots than in diminishing the 

 disease. (5). Copper sulphate, whether used in the dry form 

 or in solution, again showed its capacity for curing the 

 disease. (6). A thoroughly dry condition of soil diminished 

 the disease, though not very materially. 



Four plots were set apart to deal with the question of 

 the transmission of the disease through the dung of cattle 

 feeding upon diseased turnips. The dung was mixed with 

 ordinary soil in the proportion of three of soil to one of dung, 

 and 50 lbs. of the mixture was applied per plot. The dung 

 used on two plots was produced by cattle fed upon sound and 

 diseased roots respectively. The dung used on a third plot 

 differed from that on the two former only in so far that the 

 refuse from the animal's trough, consisting of bits of diseased 

 turnip, dirt, etc., was mixed with it. The results were : 

 (7). The percentage of diseased roots grown with dung 

 made from sound and diseased turnips was exactly the 

 same (on the two first plots), indicating that the germs of 

 finger and toe are destroyed in their passage through an 

 animal. (8). The plot receiving dung with the trotcgh 

 refuse produced 74 per cent, of diseased turnips, indicating 

 that the spores ot the disease may be communicated to 

 healthy land by permitting refuse from diseased turnips to 

 find its way directly into the manure heap. (9). The addition 

 of lime to the dung on the fourth plot practically cured the 

 disease, but also seriously diminished the yield of roots, 

 probably by liberating nitrogen.
