A7 — do not show so strongly the maiivs of tlie double infusion 

 of blood. In A2, there were a few more plants with green than 

 with purple herbage and the green ones were more productive than 

 tlie othere; these are marks of the Bound ^Tiite, and it may also 

 be said thai even the purple plants were of a light cast and that 

 nearly aU showed the influence of the dwarf habit of Round White. 

 A7, the other Round White cross, produced a lot of small plants, 

 but they were unproductive, and much over half of them had pur- 

 ple herbage. 



Three of these lots — Al, A.5, AG — were from f iiiib-i pollinated 

 by a flower on the same plant. These, then, according to popular 

 notions, should produce imifonu plants; but with that sublime 

 contrariness which is so characteristic of most of our results of 

 cix>ssing, these lots gave as variable progeny as those w'hich had 

 better right to such possessions. In fact, the lot Al was prob- 

 ably the most hopelessly mixed of any in the entire list. The 

 fruits ranged from pure white to green with white stripes, pui'ple 

 striped, light solid pui-ple and veiy dark purple; and the mature 

 fruits vai'ied from the size of an egg to that of iilack l*ekin. 

 Al)Out equal numbers of the 175 plants wei*e green and purple. 

 A5 was nearly as badly mixed, and some plants appeared wliioh 

 had the peculiar spreading habit of Early Dwarf Purple, a variety 

 which had never entered into any of the ci-osses. AG showed 

 wide variations also. A8, which was simply a selection and had 

 not been ai'tificially pollin^ited, was about as vai'iable as the r(^t. 



Soiue of the fruit« of thesie crosses were exceediugl.N' liandsonu', 

 esi»ecially one which ap])enred in Al and another iu A2. The 

 engraAing on last page shows one of them, but no black and 

 white print can do justice to it. White and pui'ple bands were 

 laid on the fniit in altenia^^e waves, which st'i'med to run off 

 the fleshy calyx lolx^ and to flow down the fruif. Efforts have 

 been made to perpetuate these remarkable type®, but they are now 

 lost. Every new attempt at crossing reminds me that the chief 

 value of the operation is the infusing of new vigor into offspring 

 rather than tlie origination of new types. 



As a whole, 543 of the 1,405 plants produced porfectl}^ green 

 ■foliage, showing the effect of the Round White. Most of the
