FINDING THEIR WAY. 279 



contrary, which I put in with her, got out at once. At 

 1 1.30 I put another bee and a fly into the same glass :

One day when I came home in the afternoon I found 

 that at least a hundred bees had got into my room 

 through the postern and were on the window, yet not
