Some correlations of the shape and absence of leaf glands with the 

 time of maturity of the fi'uit and the adiiesiveness of the pit have 

 been compiled from over 4(»<» varieties, and these correlations are 

 shown in the tiible which follows.

This table shows that of 208 early-fruiting varieties, 46 have reniform 

 glands, 130 globose glands, and 32 serrate leaves; while of 11»4 late 

 varieties, 140 have reniform glands, 50 globose glands, and 4 serrate 

 leaves. In other words, of the early varieties given there are nearly 

 three times as many with globose glands as with reniform glands. 

 On the other hand, of the late varieties, there are nearly three times 

 as many with reniform glands as with globose glands. The table 

 also shows that there are 120 early free globose to 35 early free reni- 

 form varieties, w^hile there are 89 late free reniform to 46 late free 

 globose varieties. This table is given as a step in the direction of 

 future investigations along this line, which appear warranted by the 

 correlations found to exist between the form of glands, the date of 

 maturity, the date of bloom, etc., and the little or great susceptibility of 

 varieties to curl and mildew. Such facts may prove of much impor- 

 tance when taken in connection with future work in originating hardy 

 or otherwise desirable varieties by cross breeding.
