31 cm. (12.3 in.). To show the course of egg-laying during 
the season, the accompanying table is copied from this paper. 
These observations were made during 1900 on a colony in 
which the queen was reared in 1899, egg-laying of this queen 
having begun about June 17, 1899. During the year a total 
of about 150,000 eggs were laid. The maximum egg-laying 
occurred during the period of the chief honey-flow, which 
that year was from June 1 to 12. The colony did not swarm.

In brief, the results of Dufour’s work are as follows: For 
that locality and under the conditions prevailing, the largest 
average observed was 1027 eggs a day (June 10-July 1,1898). 
The maximum occurs during a heavy honey-flow or imme¬ 
diately after. A queen about to be superseded may lay about 
400 eggs daily, while a young queen may begin by laying 
900 eggs daily (these figures probably vary with the time of 
year). Artificial swarming is said greatly to diminish egg- 
laying. It must be remembered that variation in climatic 
conditions and in honey-flows influence egg-laying and the 
results of such work would not be the same everywhere. 
Work of this character should be carried out elsewhere.
