with two entrances. Into this an army of many thousand largish ants, in
an even column three and a half inches wide, marched continually, in
well "dressed" ranks, about twenty-seven in each, with the regularity
of a crack regiment on the "march past," over all sorts of
inequalities, rough ground, and imbedded trunks of small trees, larger
ants looking like officers marching on both sides of the column, and
sometimes turning back as if to give orders. Would that Sir John
Lubbock had been there to interpret their speech!

Each ant of the column bore a yellowish burden, not too large to
interfere with his activity. A column marshaled in the same fashion,
but only half the width of the other, emerged equally continuously from
the lower entrance. From the smaller size of this column I suppose that
a number of the carrier ants remain within, stowing away their burdens
in store-houses. Attending this latter column for eighteen paces, I
came upon a marvelous scene of orderly activity. A stump of a tree,
from which the outer bark had been removed, leaving an under layer
apparently permeated with a rich, sweet secretion, was completely
covered with ants, which were removing the latter in minute portions.
Strange to say, however, a quantity of reddish ants of much larger size
and with large mandibles seemed to do the whole work of stripping off
this layer. They were working from above, and had already bared some
inches of the stump, which was four feet six inches in diameter. As the
small morsels fell among the myriads of ants which swarmed round the
base they were broken up, three or four ants sometimes working at one
bit till they had reduced it into manageable portions. It was a
splendid sight to see this vast and busy crowd inspired by a common
purpose, and with the true instinct of discipline, forever forming into
column at the foot of the stump.
