THE PLUMS OF NEW YORK. 377 



Wickson is one of the best known of Burbank's many plums. The 

 variety was first described in the report of the Secretary of Agriculture 

 in 1892 under the name Perfection and as a seedling of Kelsey crossed 

 by Burbank. In 1893 and 1894 Burbank offered for sale the control and 

 the stock of this variety but found no buyers and in 1895 introduced it 

 himself. The parentage of the variety is in doubt. Burbank considered 

 it a Kelsey-Burbank cross ; the Pacific Rural Press described it as offspring 

 of Kelsey and Satsuma ; Bailey, Waugh and the .workers at this Station 

 believe it to have Prunus simonii characters. The foliage, flowers, the 

 tree, the fruiting habit, the texture of the flesh, all indicate Simon as 

 one of its parents. According to the report of the Secretary of the Cali- 

 fornia State Board of Horticulture shipments of this plum were made to 

 New York in the season of 1897 under the name of Eureka. In 1899 it 

 was placed on the fruit catalog list of the American Pomological Society.
