in average weight, rose to fourth in carrying capacity, and stored the 

 third largest amount of honey between June 15 and July 15, but 

 was fourth in the total honey produced, which rank corresponded with 

 its carrying capacity. Colony No. 3 exceeded all others in all of the 

 factors here considered, and stored by far the largest amount of honey 

 during the season. Colony No. 4 was fourth in the number of bees, 

 fourth in the amount of honey stored between June 15 and July 15, 

 and fourth in the length of tongue, fourth in the weight of the bee, but 

 rose to second rank in carrying capacity and total honey produced. 

 Colony No. 5 was second in num.ber of bees, second in honey stored be- 

 tween June 15 and July 15, second in length of tongue, almost 

 equalling colony No. 3, which ranked first in this respect; was second 

 in the weight of the bee, but had a slightly smaller carrying capacity 

 than colony No. 4 which ranked second in carrying capacity and total 

 honey produced, and colony No. 5 ranked third in both of these re- 

 spects. Colony No. 6 ranked sixth in every feature, except in the 

 length of tongue and total honey produced. Its tongue length and 

 carrying capacity were very nearly equal to that of colony No. 2, which 

 ranked fifth in total honey produced. 



These results seemed to indicate that the bees which have the longest 

 tongues, largest bodies and greatest canydng capacities exceed, in the 

 total amount of honey stored, those possessing these factors in a lesser 

 degree. While there seems to be a direct relation between the length 

 of tongue, the size of the bee when the carrying capacity is either equal 

 or about equal, and the total amount of honey stored, yet a study of 

 colony No. 1 would indicate that if it were deficient in the size of tongue 

 and the size of bee, this disadvantage would be offset by the advantage 

 of a larger carrying capacity, because, as previously mentioned, colony 

 No. 1 ranked sixth in the length of tongue and fifth in size of bee, but 

 in its carr\-ing capacity it very nearly equalled colony No. 5 which ranked 

 third in carrying capacity, and on July 15 colony No. 1 ranked 

 third in the amount of honey stored, and at the end of the season ranked 

 fourth in total hone}' produced. This is again shown in a study of colony 

 No. 4 which ranked fourth in length of tongue and weight of bee, but 

 second in carrying capacity and total amount of honey stored. 



During both 1920 and 1921, those colonies whose bees possessed the 

 longest tongues and had the greatest size or carrying capacity, were 

 also strongest in the nimiber of bees. This may be due to the fact that 

 the length of the bee's life depends upon how rapidly its energy is 

 expended. If the bees possessing the longest tongues, the largest 

 size, and the greatest carrying capacities expend less energ}'- to bring in
