422 REGULARITY OF VISITS. 



She did not return any more that evening, but 

 made her appearance again at half-past six the next 

 morning. 



From twelve o'clock, when she had learnt her way, 

 till five, she made twenty-five visits in five hours, or 

 about five an hour, as in the previous cases. 



It struck me as curious that on the following day 

 this wasp seemed by no means so sure of her way, but 

 over and over again went to the closed window. 



Again, September 21, at 11.50 I fed a wasp.
