400 EXPERIMENTS ON POWER OF COMMUNICATION. 
37 journeys and brought 9 friends. The ant with few 
larves made 18 journeys and brought no friend. This, 
I think, is a very striking case. She was under observa- 
tion 54 hours; and the scene of her labour was the 
same throughout. The first 2 hours she had few larvee 
and brought 4 friends; then for 14 she had many larve 
and brought 21 friends; then again for 2 hours she 
had few larvee and brought no friend. 
Experiment 23.—Time, 14 hour. The ant with 
few larve made 25 journeys and brought 3 friends. 
The other made only 9 journeys, but brought 10 friends. 
Eeperiment 24.—I now transposed the glasses. 
Time occupied, 2 hours. The ant which now had few 
larvae made 14 journeys, but brought no friends. The 
other made 37 journeys and brought 5 friends. 
Experiment 25.—Time 3 hours. I put an ant for an 
hour toa full glass; she made 10 journeys and brovght 
4 friends. I then left only two or three larve: in the 
second hour she made 7 journeys and brought no 
friend. I then again filled the glass; and during the 
third hour she made 14 journeys and brought 3 
friends.
