up to 25 mg. for apple and 29 mg. for hard maple. Thus a maximum 

 load of pollen was found to be about one-third of the weight of the 

 bee and less than half that of a maximum load of nectar. It appears 

 that there must be a great difference in the specific gravity of various 

 pollens, for the loads carried from com appeared fully as large as those 

 from apple or hard maple, but they weighed only half as much.

THE COST OF POOR QUEENS 



By F. B. Paddock, Ames, Iowa 



In a previous paper' attention was called to the irregularity of colony 

 production. Records were made in a yard in which colonies having 

 queens from the same source produced from almost no surplus honey 

 to a good crop. It was further pointed out that too large a proportion 

 of colonies produced under a profitable or average crop. The estimated 

 cost of these low producing queens was placed at $18 each, the market 

 value of the honey they failed to produce under the yard average. It 

 was suggested that perhaps queens were being sold which came from a 

 low producing type. Individual record of performance was intimated 

 as a relief measure for the present unsatisfactory honey yields. 



The records made during the season 1920 were continued during the 

 present season, 1921. The summary of the records for the two seasons 

 is given in Table 1.
