I now left ofif watching for an hour. On my return 

 at 8.30 she was just carrying off a larva. 



8.40 she came back to cup 3 and took a larva. 

 8.55 she came to cup l,then to cup 3 and took alarva.

10.26 she went and examined cup 2, then to cup 3 

 and took a larva. 



At 10.45 she came to cup 3, and I went to bed. 

 At 7 o'clock the nest morning the larvae were all 

 removed. In watching this ant I was much struck by 

 the difiSculty she seemed to experience in finding her 

 way. She wandered about at times most irresolutely, 

 and, instead of coming straight across from the door of 

 the frame to the cups, kept along the side of the box ; 

 so that in coming to cup 3 she went twice as far as she 

 need have done. Again, it is remarkable that she 

 should have kept on visiting the empty cups time after 

 time. I watched for this ant carefully on the following 

 day ; but she did not come out at all. 



During the time she was under observation, from 1 

 till 10.45, though there were always ants roaming about, 

 few climbed up the walls of the cup. Five found their 

 way into the (empty) cup I, and one only to cup 3. It 

 is clear, therefore, that the ant under observation did 

 not communicate her discovery of larvae to her friends. 



The following day I watched again, having, at 7 

 A.M., put larvae into one of the porcelain cups arranged 

 as before. No ants found them for several hours. 



At. 11. 37 one came and took a larva- 

 „ 11.50 she returned and took a larva.
