in these last trees. There appeared to be much difference between individual 

 trees and but little between varieties, except that Wagener seemed very low in 

 potash. This variety has performed very poorly in this orchard. No relation 

 between potash content of the trees and the root stock was shown but this de- 

 serves further study. 



Some work has been done in tabulating and studying the data accumulated 

 during the 18 years of the life of this orchard and a publication will be made as 

 soon as the study is completed. 



Excavations were made around the stumps of trees cut out to study the root 

 distribution. This will be reported later. It was concluded that the stock in- 

 fluenced the type while the scion controlled the size of the root system. 



Studies of the Mailing types of clonal roots were continued. Surplus wood of 

 several types was grafted on short pieces of seedling roots in April and at once 

 planted. Results were as follows: 



This method of nurse root grafting may be used for propagating these stocks. 

 If allowed time to callus before planting, better results might be obtained. The 

 nurse roots were cut off and the rooted scions replanted. 



The first crop from a stool bed planted in 1933 was harvested. Rooted layers 

 per 100 stool plants were as follows: 



be larger as the plants become older. 



An orchard of 344 trees, mostly Baldwin, Mcintosh, Starking, Red Spy, and 

 Macoun budded on several Mailing stocks, was set on the fruit farm of R. S.
