August 20. — About noon I brought five bees to 

 some honey at my window. They all soon returned, 

 and numerous friends came with them. One of them

when I left off watching and shut her out. The longer 

 intervals are due to her having got some honey every 

 now and then on her wings and legs, when she lost a 

 little time in cleaning herself. 



August 21. — I opened my window at 6 a.m. No 

 bee came till at 7.33 the one above-mentioned came to 

 the honey on blue j)aper. 



I also placed some honey on orange paper about 

 two feet off. 



At 7.42 she returned to the honey on blue paper, 

 and again 

 7.55 she returned to the honey on blue paper.
