She buzzed about at the other window for a few 
minutes, which made the interval longer than 
usual.

It will be seen that the intervals of her absence 
were remarkably regular. On one occasion, indeed, 
she was only away four minutes; but this time I think 
she had been disturbed, and had not provided herself 
with a regular supply of food. 
The number of visits was fifty-one in eleven hours 
and a half. I tried whether she would be in any way 
affected by a dead wasp, so I put one on the honey; 
but she took no notice whatever. 
I observed with other wasps, that when the open 
window was not the shortest way to their nests, they 
had a great tendency to fly to that which was in the 
right direction, and to remain buzzing about, there.
