 6.25 P.M. She made forty-five visits to the honey, but

Experiment 2. — The following day this wasp began 

 working — at least, came to my room for the first time at 

 6.55 A.M., and went on passing backwards and forwards

 journeys, and did not bring a single friend. 



Experiment 3. — Another wasp was watched from 

 6.16 A.M. till 6 P.M. She made fifty-one journeys, and 

 during the day five other wasps came to the honey. I

Eseperimemt 4. — Another wasp was watched from 

 10 A.U. to 5.15 F.M. ; she made twenty-eight joumeya,
