"Froginurc/' there was one uf the "siekly"" yellow plants to four 

 of the usual green type. Anioaig the "Princess" crosses, compris- 

 ing twenty-two plants, there was only one that showed the peculiar 

 foliage in question, but this one was strongly marked and indi- 

 cates that the characteristic may be expected tO' apjiear in small 

 numbers for an indefinite time in crosses where one parent is 

 "yellow-leaved." 



Concerning the color of the fruit, it is not easy to state the 

 results of the observations in a few words. The reds, pinks and 

 yellows are fairly constant, and all attempts to develo]) inter- 

 mediates have been failures, excepting that, for example, the 

 "reds," so-called — ^wliich are, in fact, a dark orange mixed with 

 red — have in some instances lost all of the red and developed pure 

 orange fruits. Seeds from these orange fruits do not give fruits 

 after their kind, 1)ut the old mixture of colors. When the "reds" 

 and "pinks"- — which difi^'er from the "reds" in having less orange 

 — are bred together, the offspring are easily arranged under the 

 tv/o parental colors, oue-f(»urth being "pinks." Here, again, there 

 are slight modifications. 



With the yellow^ color there is more hope of getting a combina- 

 tion with the reds and the stri\-ing after a deep blush upon a yellow 

 background, like a peach in its perfection of color, may not be in 

 vain. 



The so-called "white"-fruited sorts have been grown only to a 

 limited extent, and the crosses obtained are few. Thus the "Ivory 

 Ball," in combination Avith "Duke of York" (32/175), in its 

 second generation, gave three plants with pink fruits, like the male 

 parent, and two with very pale yellow fruits, styled "whitish 

 lemon" in the note-book record. This last is quite different from 

 the mother fruit, which does not show the yellow. A similar result 

 was obfained Avith the "Aristocrat," three of the plants giving light 

 yellow fruits, while two were red, but, most interesting of all, 

 showing the yellow as Idotches upon the surface. When the "Gold 

 Ball" is bred with "Ivory Ball" (172/175) there results in the 

 first generation a fruit that is of a lighter yellow than the male. 

 In the next generation the same lighter color is retained as a con- 

 stant average between the two parents. In the cross with "Y'ellow 

 Cherry," the "Ivory Ball" (175/183) produced a pale yellow fruit 

 of the size of the "})lum," and again reduced the amount of yellow
