nearly globular and very dark purple f raits. One fruit was 

 obtained in 1889, as a result of crossing these two varieties:. The 

 seeds of this fruit gave in 1890 a series of plants which were 

 almost exactly intermediate between the pavents in size and 

 other characters. The young shoots were much like the pis' Hlate 

 parent — Kound WTiite — but as they became older, the upper 

 surface of the stems, the petioles and the veins of the leaves 

 assumed the purple tinge of the male pareut. hi form and size,

 dark j>ui7jle changed to a dull greenish hu6, and the light ai>ex 

 became metallic gray with a faint tinge of purple, and streaks 

 of grayish purple extended towards the base. The accompanying 

 figure shows the extent of variation in 1890, or a fruit of every 

 type obtained. 



From the first brood of this cross, 1890, eight fruits were 

 selected or again crossed, as parents for succeeding crops. These
