The length of the "Black Valentine" plants was greatest 

 when grown in a hill close to their fellows, but in the "Davis 

 Wax" the difference was but slight. Varietal peculiarities may 

 account for the tendency to be bushy or to "run."" 



The weight of the normal plants was taken after they had be- 

 come quite dry and the leaves and some small branches 

 had fallen. It was quite impracticable to get the other plants 

 into the same condition and therefore the table of average 

 weights is not fully comparable in all its parts. At a glance it 

 is seen that the grouped plants had less dry weight than the 

 others, and the average number of pods (12) was less than half 

 that of the ones grown singly (25). 



Pods grown alone uniformly weighed and measured more 

 on the average than those produced without limitation on the 

 plant. The table shows that the weights were sometimes more 

 than three times that of the normal crop and in measurements 

 the increase was in both length and breadth of the pod. 



During the autumn months this experiment was very striking 

 because of the maturing and defoliation of the normal plants 

 which stood leafless among the limitation plants which increased 

 to unusual size, bloomed in profusion and held the foliage green 

 for weeks after the first frosts, from which they had been arti- 

 ficially protected. 



Here the pods or their contents were not materially different 

 from those produced normally but it remains to be determined 

 what potencies may be stimulated or what new ones acquired 

 by the conditions under which the oft'spring were nurtured and 

 developed. 



Plate XIX shows unsatisfactorily the differences at a time 

 when the pods were maturing upon the check plants. The 

 "Black Valentine" with full crop and with no pods in mid-season 

 is shown at i and 2 respectively, and the "Davis Wax" at 3 

 and 4. The contrasts here are far less than developed later in 

 the season. 



BUSH SQUASHES. 



The limitation test was attempted with two varieties of bush 

 summer squashes, namely, "Mammoth White Scallop" and 

 "Strickler's" ; but no second fruits formed upon the former. 

 Seven plants of the "Strickler's" matured a single fruit each, 

 while only two had a brace of squashes of full size. From 

 these nine instances the following figures are obtained :
