seemed to be no observed difference among the other varieties, 

 namely, "Mammoth," "Elmira," ''Columbian," "Colossal," 

 "Brunswick" and "Cross Bred," and for these the record is 50 per 

 cent, of rustiness. 



The same area gave 77 per cent, last year. 



It was observed that the rust was much more abundant upon the 

 ■west than on the east side of the plants, and it is suggested that the 

 dew dried off quicker on the side toward the morning than the 

 afternoon sun, and then the spores did not have as good an oppor- 

 tunity to infect the plants as upon the west side, when the moisture 

 remained longer.

 four preceding years. 



The plan of the experiments is given below :
