POWER OF COMMUNICATION. 367 
I now left off 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 1,then to cup 8 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 larve were all 
removed. In watching this ant I was much struck by 
the difficulty 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 1, and one only to cup 3. It 
is clear, therefore, that the ant under observation did 
not communicate her discovery of larve to her friends. 
The following day I watched again, having, at 7 
A.M., put larve 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.
