had been graded strictly on the basis of the commercial quality of the 
cured fruits most of them would have been classified as second grade 
or culls. The results of the 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 the 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 limbs growing in somewhat horizontal positions. Some of

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
