EXPERIMENT STATION EEPOKT. 497 



These types are given in the above order, witli corresponding 

 numerals, in Plate XI. The "Cheese" forms (Xos. 21 and 22) 

 naturally come in between "rectangular" and "oval" types, and the 

 '^spherical" (No. 23) is just Ijefore the "ovals," also, but, not having 

 specimens to show the lacking forms in the tlicoretical scheme for 

 these general types, the ones at hand were added at the end. 



EXPERIMENTS WITH XITINTER SQUASHES. 



In 1903 crosses were secured between the "Hubbard" upon "Boston 

 Marrow" and "Delicious" upon "Golden Hubbard," but during last 

 year only one fruit was obtained from these crosses, namely, of the 

 "Delicious-Golden Hubbard," and tliis had been pollinated with the 

 other cross above named — that is, the seeds carried the "blood" of 

 four varieties. 



It is with much difficulty that winter squashes, particularly of 

 the "Hubbard" group, can be grown, on account of the swarms of 

 beetles that attack the seedlings and the grub that afterward works 

 in the base of the stem of any that survive the striped "bug." Beside 

 these insect enemies there is a wilt disease, more or less in evidence, 

 so that it is necessary to plant very liberally to insure a small stand of 

 plants. During the present year it was only through a second plant- 

 ing and daily attention that fruits w^ere secured of the above crosses. 



About twenty fruits were obtained of the "Hubbard" upon the 

 "Boston Marrow" cross, and samples of these are shown in the upper 

 row of Plate XII. The squash to the left, marked "1," is a fair 

 specimen of the "Hubbard" or male parent, and the mother ("Boston 

 Marrow"), marked "2," is shown in a small fruit at the right end, 

 while the crosses, one of them marked "V2/' lie between. As a rule, 

 the shape more nearly resembles the male, while in color there are 

 strong indications of the cross. Nearly all of the fruits were of a 

 pale or "pea" green, with the cream color showing in more or less 

 well-defined streaks. In some instances the fruits were more cream 

 orange than green, and none of them was of the solid olive green 

 characteristic of the "Hul)bard." Two large fruits of nearly the 

 same general shape, but one green and the other yellow, were grown 

 upon the same plant. It was generally true that the fruits of the 

 same vine were not duplicates in appearances. At tlie time of writing 

 it is too soon after the harvest to give full details of the internal
