In the plate the plan is to show five seeds of each commercial 

 sort that is inAolved in the crosses represented and ten seeds of 

 each cross, some of the latter being separated into two sets of five, 

 each representing differences where these are apparent. At 7 is 

 shown a set of ten similar seeds that are a cross of the "Golden 

 Hubbard" (4) and "Faxon" (30) — 4/30. The seeds of both 

 parents are chalky white, with the one longer and the other broader 

 than the average of the two, as shown in the crossed se-eds. The 

 cross at 9 is similarly a combination between two kinds, with no 

 marked difference in their seeds. 



The seeds at 11 are of a hybrid between the "Warren" (7) upon 

 the "Japanese" (31) — 7/31 — and they are quite midway between 

 the two, the "Warren" being large and chalky, while the mother 

 (31) has very small seeds for a vine squash, and of a brown color 

 and a distinct rim. The outer coat in the hybrid seeds is brown 

 and rimmed. In another fruit, from the seeds of the same mother 

 fniit as the last, the seeds (12) are scarcely diiferent from the 

 "Japanese" alongside at 13, and do not show indications of hybrid- 

 ity. The seeds at 14 are shells merely, from a full-grown fruit of 

 "Japanese" (15) upon "Mammoth Chili" (1<))> and are practi- 

 cally the same as of the mother, plump seeds of which are to their 

 right. That it is safe to infer the size and shape of plump seeds 

 frnm empty seed coats is demonstrated in nearly every squash 

 fruit, for there are frequently a large fraction without embryos, 

 and they agree with ])lump ones in external qualities. In the cross 

 of 16/3, "Mammoth Chili" upon "Delicious," there is a marked 

 difference in the seeds of the two parents, and here, again, from 

 the same fruit two sizes and shades of color also are separated, as 

 shown at 16 and 17. 



At 19 is a group of ten seeds from a fruit that was grown from 

 seed secured by breeding the "Mammoth Chili" upon the "Japa- 

 nese," but the seeds do not differ materially from the mother 

 species. 



A hybrid 1)etween the "Winter Crookneck" (18) and the "Deli- 

 cious" (18/3) is shown at 21. The seeds (20) are white, like the 

 mother, but much smaller, and are in striking contrast with the 

 "Crookneck," which are more oval, flat, brown and rimmed. The 

 above "Winter Crookneck" upon "Faxon" (18/30) gave seeds 

 brown and thin (22), resembling in these respects those of the 

 male parent as shown at 20, which were very unlike those of the 

 ])lnmp, pure wliite, smooth ones of the mother shown at 31.
