!° A potato identical with this is known under the name Dooley also; the variety Dooley used in these 
trials is an Up-to-Date type. 
11 The original Dearborn was a Rural type. The present variety undoubtedly belongs to the Pearl 
group. 
u The original Snowflake is probably not now in existence; the variety under consideration is a renamed 
Pearl. 
18 This variety is widelv and successfully grown as an immune potato in Newfoundland. 
m A light and a dark strain of this variety exist, but the types are no t wholly fixed.
