334 PERFECT SOCIETIES OF INSECTS. 
interesting anecdote afford! Another experiment which he tried made the 
contrast equally striking. He put a large portion of one of these mixed 
colonies into a woollen bag, in the mouth of which he fixed a small tube 
of wood, glazed at the top, which at the other end was fitted to the entrance 
of a kind of hive. The second day the tube was crowded with negroes 
going and returning :—the indefatigable diligence and activity manifested 
by them in transporting the young brood and their rufescent masters, 
whose bodies were suspended upon their mandibles, was astonishing, 
These last took no active part in the busy scene, while their slaves showed 
the greatest anxiety about them, generally carrying them into the hive ; and 
if they sometimes contented themselves with depositing them at the en- 
trance of the tube, it was that they might use greater dispatch in fetching 
the rest. The rufescent when thus set down remained for a moment 
coiled up without motion, and then leisurely unrolling itself, looked all 
around, as if it was quite at a loss what direction to take ;—it next went 
up to the negroes, and by the play of its antennas seemed to implore their 
succour, till one of them attending to it conducted it into the hive. 
Beings so entirely dependent as these masters are upon their slaves, for 
every necessary, comfort, and enjoyment of their life, can scarcely be sup- 
posed to treat them with rigour or unkindness:—so far from this, it is 
evident from the preceding details that they rather look: up to them, and 
are in some degree under their control. 
The above observations, with respect to the indolence of our slave- 
dealers, relate principally to the rufescent species ; for the sanguine ants are 
not altogether so listless and helpless ; they assist their negroes in the con 
struction of their nests, they collect their sweet fluid from the Aphides ; 
and one of their most usual occupations is to lie in wait for a small species 
of ant, on which they feed ; and when their nest is menaced by an enemy 
they show their value for these faithful servants by carrying them down 
into the lowest apartments, as to a place of the greatest security. Some- 
times even the rufescents rouse themselves from the torpor that usually 
benumbs them. In one instance, when they wished to emigrate from their 
own to a deserted nest, they reversed what usually takes place on such 
occasions, and carried all their negroes themselves to the spot they had 
chosen, At the first foundation also of their societies by impregnated 
females, there is good Yeason for thinking, that, like those of other species, 
they take upon themselyes the whole charge of the nascent colony. J. 
must not here omit a most extraordinary anecdote related by M. Huber. 
He put into one of his artificial formicaries pupa of both species of the 
slave-collecting ants, which, under the care of some negroes introduced 
with them, arrived at their imago state, and lived together under the same 
roof in the most perfect amity. 
These facts show what effects education will produce even upon insects; 
that it will impart to them a new bias, and modify in some respects their 
usual instincts, rendering them familiar with objects which, had they been 
educated at home, they would have feared, and causing them to love those 
whom in that case they would have abhorred.— It occasions, however, 
no further change in their character, since the master and slave, brought 
up with the same care and under the same superintendence, are associated 
in the mixed formicary under laws entirely opposite.'

have been observed amongst exotic ants by M. Lund, who mentions a species 0
