On another occasion, while a procession of Amazon ants was on its way to plunder a nest of _F. fusca_, before it arrived Forel poured out a sack-full of sanguine ants, and made a break in the nest:-- The sanguine ants pressed in, while the _fusca_ came out to defend themselves. At this moment the first Amazons arrived. When they saw the sanguine ants they drew back and awaited the main army, which appeared much disturbed at the news. But once united, the bold robbers rushed at their foes. The latter gathered together and beat back the first attack, but the Amazons closed up their ranks and made a second assault, which carried them on to the dome and into the midst of the enemy. These were overthrown, as well as a number of _F. pratensis_, which Forel at this moment poured out on the nest. The conquerors delayed for a moment on the dome after their victory, and then entered the nest to bring out a little of the valuable booty. A few Amazons which were mad with anger did not return with the main army, but went on slaughtering blindly among the conquered and the fugitives of the three species, _fusca_, _pratensis_, and _sanguinea_. The ravished _rufibarbes_ once became so desperate at their overthrow that they followed the robbers to their own nest, and the latter had some trouble in defending it. The _rufibarbes_ let themselves be killed in hundreds, and really seemed as though they courted death. A small number of the Amazons also sank under the bites of their enemies. The nest contained slaves of the _rufibarbis_ species, which on this emergency fought actively against their own race. There were also slaves of the species _fusca_, so that the nest included three different species of ants.
