The two varieties of summer squashes differ greatly in the 

 form and color of the fruits, those of the "Crookneck" (5) pro- 

 ducing long yellow and somewhat bell-shaped fruits, with much 

 variation in the shape of the "neck," some being slightly and 

 others much curved, while a few are thickly beset with wart-like 

 outgrowths, while others are nearly smooth. The "Long Island 

 Scallop" (6) is uniformly white, disk-shaped, and, except for 

 their scalloped sides, the fruits are comparatively smooth. 



One of the results of the combination of these two varieties 

 in the first season after the cross was made in the plants, is the 

 remarkable vigor in the plants, in striking contrast with the 

 parent types, grown near by for comparison. 



In the cross represented by the fraction 5-6 — that is, with the 

 "Crookneck" as the male parent — the fruits combine the shape 

 of the two parents ; in place of the long yellow crook neck of the 

 one and the disk-shape of the other, there often results a jug- 

 shaped fruit, with the shallow scallops long, making a fluted 

 surface, narrowing into a straight, short smooth neck. 



The upper rov/ of fruits in Plate IV. shows the parent "Crook- 

 neck" (5) at the left, and a series of types of the crosses with 

 it as the male at its right, while in the lower row is the "Scallop" 

 (6) at the right end, and the crosses with it as the male to its 

 left. In the upper row it is seen that the "Crookneck" type is 

 strongly adhered tO' in No. 2, and less so in No. 3. Both of 

 these types carry the orange color of the parent in distinct bands, 

 with irregular borders, between the more or less distinct scallops. 

 No. 4 has a distinct lemon color throughout its whole surface, 

 while Nos. 5 and 6 approach the "Scallop" type, particularly 

 in the color which may be termed a cream-white. There seems 

 to be some correlation between the orange color and the shape 

 of the fruit ; that is, the nearer the fruit approaches the shape 

 of the male parent, the nearer it does so in color. There does 

 not seem to' be the same association between shape and warts, 

 or warts and color, as these protuberances are produced without 

 apparent order. 



In the lower half of the plate, when the "Scallop" is the male, 

 the fruits are arranged wdth those most like the female parent 

 near it at the right, in this series there is 'an entire absence of 

 orange or lemon color of the female parent, but the shape of 

 the "Crookneck" is suggested in No. 7. This type and some 

 of the others have a delicate pink white which is solid in No. 7, 

 but limited to bands in No. 8. The fruits, Nos. 9, 10 and 11 

 are cream white.
