are small, flowers cup-shaped, li_dit lemon-yellow, and the fruits few, 

 medium small, light yellow and nearly seedless. The flesh is particu- 

 larly fine flavored. Tiie plants, three feet apart each way, covered the 

 ground devoted to tiie l)loek, and flowered up to the killing frosts near 

 Xovember 1st. 



The plants of this season were not unlike those of previous years, 

 and the type seems to be well fixed. All attempts to cross any other 

 .'^ort upon it have uniformly failed, and the only way to get a half-blood 

 seems to be by using this one as the pollinator. Two plants were 

 grown in the greenhouse last winter for this purpose, but no crosses 

 were obtained upon it or with it upon other varieties. 



There was another type of seedlessness met with in the greenhouse 

 that is illustrated in Plate VII. It was first observed that certain 

 young fruits of the hybrid of "Currant"' upon "Stone" ceased to en- 

 large and began to turn of a pale green, while others in the long, 

 slender cluster conuinued to grow until several times the size of the 

 first mentioned. The color and size of the little fruits were so nearly 

 those of peas somewhat too old for eating that the name "Pea" toma- 

 toes was given to them. In time all the fruits upon a cluster, whether 

 of the size of peas or cherries, ran through the ordinary color changes 

 until they were of the tomato-red, or ripe, condition. The knife 

 reached the truth of the supposition in each case of the small fruit, for 

 they were invariably seedless, and the flesh filled up the interior, with 

 perhaps a small, empty seed cavity. 



The same thing was met with later on, when the cross of the 

 ^'Crimson Cushion" upon "Sumatra Fig" came into bearing. The 

 upper part of Plate YII. shows some of the clusters of this combina- 

 tion between a large and small-fruited variety. Xear the middle of 

 the group, where the label — about an inch long — is situated, the whole 

 cluster is of the small, seedless sort. They were all ripe — that is, of a 

 red color — excepting the terminal one. A section through one of the 

 fruits shows that with these there are three cavities well toward 

 the center of the solid flesh. The clusters to the right and left show 

 the size of the seedless, as compared with the seed-bearing fruits, when 

 both are of the same color of maturity. The seedless fruits obtained 

 a certain uniform size that did not differ but slightly from their aver- 

 age. In short, upon these plants there were two distinct sizes of fruits, 

 the one seed-lx^aring and the other seedless.
