The width only was taken on account of the difficulty in finding a 
good point at the base of the wing from which to measure the length. 
The results are so uniform that the width probably gives sufficient 
data from which to draw conclusions. 
Of the four hives studied, numbers one and two were very weak. 
Number three was a strong hive which made forty (40) pounds of 
extra honey in the summer of 1900. Number four was weaker than 
number three and made only ten (10) pounds of extra honey. 
The complete measurements are too long to give in detail, and 
the averages only will be offered here.

As to the first query concerning the individual variations in a 
single hive the complete table shows that No. 1 varies from 18-21 
hooks, No. 2 from 17-21, No. 3 from 18-23 and No. 4 from 17-21. The 
right wing is taken as the standard, and the most active hive, No. 3. 
shows the greatest individual variation. One bee in this hive had 
only sixteen hooks, the remaining three being straight spines, show- 
ing how the hooks have beep modified from ordinary hairs, This
