1898 | EARLY VIEWS OF PRUNUS DOMESTICA 427 
culture is, I think, able to make a better classification out of 
fresh whole cloth. I have no doubt that a re-study and re-classi- 
fication of the horticultural varieties of Prunus domestica would 
be avery proper and profitable thing at this time. If any one 
is inclined to attempt that work, this review of the early history 
of varietal types ought to be of some use. 
In conclusion I wish to acknowledge my indebtedness to 
Professors W. W. Rowlee and L. H. Bailey for help in looking 
up these questions. The library of Cornell University has been 
of especial service.
