Belt considered to be the most intelligent of all the insects of that part
of the world. On one occasion he noticed a wide column of them trying to
pass along a nearly perpendicular slope of crumbling earth, on which they
found great difficulty in obtaining a foothold. A number succeeded in
retaining their positions, and further strengthened them by laying hold of
their neighbors. They then remained in this position, and allowed the
column to march securely and easily over their bodies. On another occasion
a column was crossing a stream of water by a very narrow branch of a tree,
which only permitted them to go in single file. The ants widened the
bridge by a number clinging to the sides and to each other, and this
allowed the column to pass over three or four deep. These ants, having no
permanent nests, carry their larvae and pupae with them when marching. The
prey they capture is cut up and carried to the rear of the army to be
distributed as food.
