increased to twelve, and the weather having some- 
what improved, I decided to leave the nest where it 
stood on its table in the study, and to let the workers 
fly in and out through the open window. 
Although this window occupied but one-fourth 
of the windowed area of the room, and was opened 
only at the top to an extent of about one-third of its 
height, the workers seldom flew against the glass. 
The window was closed in the evening when all the 
bees had returned, about 7-30 p.M., but earlier on 
cold days, and later on very warm ones. The nest, 
which was provided with an earth-floored vestibule, 
was shut up at the same time. Next morning 
about 8.0, if the weather seemed promising, the 
nest and window were opened, but if there was a 
high wind the bees were kept confined to their 
quarters, and when necessary were fed. The colony 
flourished well, barring an accident to be mentioned 
later, and in August, when the weather grew warmer, 
it became entirely self-supporting, and reared a 
number of males and queens. No doubt it would 
have done still better if the opening in the window 
had been nearer the ground—it was 8 feet above 
it, for in a gale of wind it was only by exercising 
great skill that the workers were able to steer in, 
and many must have got battered and lost. It was 
surprising how well they found their way in the 
subdued light of the room. Sitting at my desk J 
was almost in their line of flight, but they never 
molested me. 
Of course it was very easy and pleasant to make
