270 RELUCTANCE OF ANTS 
turning as in the previous experiment, ten ants, one 
after another, continued their course, thus coming out 
of the box at the end furthest from the nest. When 
ten ants successively had, under these circumstances, 
gone wrong, to make the experiment complete, I tried 
it again, everything being the same, except that 
there was no box. Under these circumstances five 
ants, one after the other, turned directly the table was 
rotated. 
From these experiments, therefore, it seems clear 
that in determining their course the ants are greatly 
influenced by the direction of the light. 
March 27.—I let out two ants imprisoned on the 
25th, and placed them on the larve, which I put on a 
column 7 inches high, covered with blue paper, and 
communicating with the nest by the paper path 
(4, Fig. 29) arranged as usual, but supported on 
pins. At first I arranged it as shown below, placing 
the larve at M, on a table 18 inches in diameter, 
Fig. 29. so that the ants, on arriving at 
the larvee, made nearly a semi- 
circle round the edge of the 
, table. I then gradually moved 
the larve to m’ and afterwards 
to mM’. The ants, however, 
obviously knew that they were 
going unnecessarily round. They 
ran along the paper bridge in a very undecided manner, 
continually turning round and often coming down the
