SUMMARY. 39 



Among those which have been widely tested, the following deserve 

 mention as of the resistant class: Dakota Red, Rustproof, Irish Cob- 

 bler, Sir Walter Raleigh, Doe's Pride, and White Beauty. Certain 

 European varieties of the disease-resistant type seem to retain that 

 character when grown in this country, e. g., Professor Maercker and 

 Sutton's Discovery. There is much of promise in certain new varie- 

 ties under trial at the Vermont station. Several new sorts of reputed 

 disease resistance have recently been place<^l on the market by American 

 seedsmen, e. g., Harris's Snowball, Dib])le\s Ionia Seedling, Burpee's 

 Vermont Gold Coin, and Johnson's Norcross, Star of the East, and Bab- 

 bitt. Those having opportunit}" should carefully observe the relative 

 disease resistance of these and also of other new varieties. 



The evidence at hand seems to justify the hope that the coordinated 

 efforts of potato specialists working from both the practical and the 

 scientific standpoints may soon result in the development of varieties 

 of potatoes combining general excellence with a high degree of disease 

 resistance. All who can do so are urged to aid toward the accomplish- 

 ment of this end.
