UF ECONOMISING LABOUR. 241 
greater number of the larvae had been carried off; so 
I put a fresh lot in the cell. The ants were busily at 
work, At 3 i.m.I visited them again. They were 
still carrying off the larve, and all going round. At 
6 a.M. the larve were all removed. I put a fresh lot, 
and up to 9 a.m. they went on as before. 
The following day (October 17) I took two longer 
sticks, each 6 feet 6 inches in length, and arranged 
them in a similar manner, only horizontally instead of 
vertically. I also placed fine earth under the glass 
supporting the larve. At 8 o’clock I placed an ant on 
the larvee; she took one, and I then coaxed her home 
along the sticks. She deposited her larva and im- 
mediately came out again, not, however, going along 
the stick, but under the larve, vainly reaching up and 
endeavouring to reach the glass. At 8.30I put her 
on the larve again, and as she evidently did not know 
her way home, but kept stretching herself down and 
trying to reach the earth under the glass cell, I again 
coaxed her home along the sticks. At 9.3 she came 
out again, and again went under the larve and wandered 
about there. At 10 I put her on the larvee and again 
helped her home. At 10.15 she came out again, and 
this time went to the stick, but still wanted some 
guidance. At 10.45 she again reached ihe frame, but 
immediately came out again, and I once more coaxed 
her round. After wandering about some time with a 
larva in her mouth, she dropped down at 11.14. After 
depositing her larva, she came out directly and went
