a simplex condition. The fruit shape in the progeny of these 

 crosses is intermediate, while the size is very variable, indicating 

 that one or more of the progenitors of the parents must have 

 borne small fruits. Esopus carries sweetness as a recessive, there 

 being 7 sweet, 25 subacid and 1 acid apple, a close approxima- 

 tion to a 3 :1 ratio. 



Green Newtoicn. — The inheritance of fruit characters in this 

 variety are based on thirteen individuals obtained from crosses 

 with Ben Davis. If Ben Davis carries only red and Green Xew- 

 town only yellow, all the progeny should have been heterozygous 

 for these colors, but 8 R R and 5 R y apples were obtained. 

 Perhaps the light blush on the Green ISTewtown signifies the pres- 

 ence of a red unit factor, but this point can be settled only by 

 growing selfed seedlings. As previously noted, the Green Xew- 

 town shape is more prepotent than the Ben Davis — the oblique- 

 ness of the K^ewtown, in particular, appearing in the offspring. 

 The fruits of the progeny did not fall below either parent. This 

 fact indicates that the progenitors of the Green Xewtowm bore 

 large fruits, for if small size is carried as a recessive in Ben 

 Davis, a union of small gametes would probably have taken place 

 even though the numbers are small. Sweetness appeared in a 

 ratio of nearly 3:1, which signifies that this character is carried 

 as a recessive. 



Jonathan. — This variety carries only red in its gametes, as 

 in the eleven progeny obtained from a cross with Ben Davis, no 

 evidence of yellow was noted. Jonathan proved to be the more 

 prepojtent parent in tlie transmission of shape, for nine of the 

 eleven seedlings resembled the former. Sweet apples appeared 

 in the proportion of 2 :9, which closely approximates a 1 :3 ratio, 

 based on sweetness as a recessive to acidness. 



Lawver. — Ko h^q^otheses can be advanced as to the inherit- 

 ance of this varietv's characters, as onlv one seedlins:, obtained 

 from a cross with Mcintosh has been described. Its dark red 

 color, however, suggests an absence of yellow. 



Mcintosh. — Three R y fruits appeared in the eleven Ben 

 Davis X Mcintosh seedlings, and one R y in the La^^we^ 

 cross. If the Ben Davis and Lawver are pure reds then Mcin- 

 tosh must have supplied the yellow in both cases. The white
