coaniit" for the otiier half there is a well developed shell in all 

 crosses, and in the last set where "Mammoth" is a half, there is 

 a nearly even division between the shell and no shell. 



In number 4 the eiffect of the "Cocoanut" is noticed in all ex- 

 cepting the third combination. The shell producing force is 

 stronger than the non-shell forming power. 



This last fact is very evident in the next three instances, which, 

 when combined, show that with equal parts of shell and no shell 

 the progeny shows 205 shell to ninety-three non-shell producing 

 plants. Thus it is seen further on that ''Strickler^' is able to hold 

 its shell evenly when "Cocoanut" is three-fourths and when 

 "Strickler" is three-fourths — all the fruits are with shell. 



In number 7 there is a large representation of a shell and no- 

 shell sort, and the figures here further show that the "Mammoth" 

 even when represented by only one-fourth is able to produce 61 

 per cent, of plants with shells to the fruits. 



The subject of the shell has not been studied with the compound 

 microscope, and the test, when so many fruits were represented, 

 was necessarily crude and consisted in thrusting, or attempting 

 to thrust, a sharpened nail fitted into the end of a cane into the 

 flesh of the squash. 



By assembling all the above instances where the two factors are 

 evenly balanced and results decisive it is found that the shell to 

 the non-shell is as 152 to 113. 



THE "sTRICKLER-COCOANUt" CROSS (11/19). 



There were three rows of fourteen hills each of the blend of the 

 "Strickler" upon the "Cocoanut." This is the union of a long, 

 large, often bent-neck, warted, dark orange shell, bush summer 

 squash with a nearly round, grooved, small belted gi*een tip, or 

 variously striped green, light orange and cream vine winter squash. 



The following table shows some of the facts that were draAvn
