A digest of 98 reports" on peach varieties in respect to the form of 

 glands, earliness or lateness of ripening, and adhesion or nonadhesion 

 of the pits, as these characters may or may not be related to suscepti- 

 bility to curl, is given in the following table.

In the above table a most striking correlation appears between 

 peach varieties with serrate leaves and susceptibility to curl. All 

 the six varieties for which full information, could be obtained are 

 little susceptible, which is all the more interesting from the fact that 

 the varieties with serrate leaves have long been known to be very
