had been graded strictly on tho ()asis of the commercial ([uality of the 

 cured fruits most of them would have been classified as second grade 

 or culls. The results of tlio studies of the behavior of the fruits of this 

 strain in the curing room emphasizes the importance of this phase of 

 these studies and its desirability in the work of tho selection of parent 

 trees as sources of bud wood for propagation. 



The habit of growth of the trees is spreading, as shown in figure 5, 

 the main Hmbs growing in somewhat horizontal positions. Some of

 of this strain grow vijorously and attain great size, but produce only light crops of inferior fruits, which 

 are lacking in juice and acidity. 



the branches, particularly the very vigorous growing vegetative ones, 

 or suckers, have an upright habit of growth. The trees of this strain 

 usually develop more suckers than those of the Eureka strain. 

 The general appearance is that of a wide-spreading shade tree. The 

 leaves are usually large, tapering to sharp points, and profuse, and 

 the margins are usually smooth or slightly wavy and have a deep- 

 green color. Frequently the large leaves are acutely pointed at the
