To determine whether any relation exists between stolon length 
and tuber weight, the data shown in Table IV have been brought 
together in correlation form in Table V. 
While there appears to be a slight trend toward negative correla- 
tion, the coefficient of — 0.112 is but little more than twice the 
probable error; therefore it is to be regarded as having little signifi-
