crossed with Sujbton, but in other crosses gave only reds of more 

 or less intense shade. No sweet apples appeared among the Spy 

 seedlings. 



Mcintosh, tho'Ughf a sub-acid variety and crossed with two other 

 siub-acid kinds, gave two sweet seedlings. Most of its progeny 

 were red, but four of them were yellow proving Mcintosh a bearer 

 of that color in spite of its dark red skin. The pure white of its 

 flesh is evidently a weak character as it was hidden in most cases 

 by the yellower flesh of the other varieties of the crosses. 



Ben Davis carries sweetness as a recessive character, since some 

 of its descendants were sweet in each of the crosses where several 

 seedlings were obtained. It did not notably impress its shape 

 when crossed with Jonathan or Green l^ewtown ; but did so about 

 equally with the other varieties with which it was bred. In size, 

 most of its descendants are intermediate between the parents, but 

 with Green Newtown some of the seedling fruits are larger than 

 either parent and none smaller. In color, all the Ben Davis seed- 

 lings are red unless the yellow could come from the other parent. 



Green Newtown appears prepotent in transmitting its shape, 

 the obliqueness of this parent appearing in nearly all the offspring ; 

 and all are equal or superior in size to either parent. Nearly one- 

 fourth of the Green Newtown seedlings are sweet, and five out of 

 the thirteen showed yellow color. 



Jonathan carries red color only, and gives its shape to most of 

 its progeny; Mother probably transmits red only, and gave eight 

 sweet apples among its twenty descendants ; and Ralls probably 

 carries only red and a strong shape-determining factor. 



Regarding other varieties the data are too limited to justify spe- 

 cific statements.
