"And which of them built this ant-hill?" inquired Dick.
"The bellicosi!" replied Benedict, pronouncing the name with as much pride as if he were eulogizing the Macedonians or some warlike nation of antiquity. "Bellicosi," he continued, "are to be found of every size. There is as much difference between the largest and the smallest of them as there is between Hercules and a dwarf; the workers are about one-fifth of an inch long; the soldiers, or fighting-ants, are half an inch; whilst the males and females measure four fifths of an inch. There is another curious species, called 'sirafoos,' which are about half an inch long, and have pincers instead of mandibles, and heads larger than their bodies, like sharks. In fact, if sharks and sirafoos were placed in competition, I should be inclined to back the sharks."
"And where are these sirafoos most generally to be found?" said Dick cautiously.
"In Africa, in the southern and central provinces. Africa may truly be termed the land of ants. Livingstone, in the notes brought home by Stanley, describes a battle which he was fortunate enough to witness between an army of black ants and an army of red. The black ants, or drivers, which are what the natives call sirafoos, got the best of it; and the red ants, or 'tchoongoos,' after a very resolute defence, were obliged to retire defeated, carrying their eggs and young ones with them. Livingstone avows that he never saw the warlike instinct so strongly developed as in these sirafoos; the stoutest man, the largest animal, a lion or an elephant, quails before the grip of their mandibles: no obstacle impedes their progress; no tree is too lofty for them to scale, and they contrive to cross wide streams by forming their own bodies into a kind of suspension bridge. Equally amazing are their numbers; Du Chaillu, another African traveller, relates how it took more than twelve hours for a column of ants to file pass him, without a moment's pause in their march. These numbers, however cease to be so surprising when it is explained that their fecundity is such that a single female of the termites bellicosi has been estimated to produce as many as sixty thousand eggs a day. These Neuroptera furnish the natives with a favourite food, grilled ants being considered a great delicacy."
"Have you ever tasted them?" asked Hercules, with a grin.
"Never," answered the naturalist; "but I am in hopes I shall have a chance of doing so very soon."
"Surely you don't imagine yourself in Africa!" said Tom suddenly.
"Africa! no; why should I?" replied Benedict; "but, as I have already seen a tzetsy in America, I do not despair of having the satisfaction of discovering white ants there too. You do not know the sensation I shall make in Europe when I publish my folio volume and its illustrations."
It was evident that no inkling of the truth had yet entered poor Benedict's brain, and it seemed likely that it would require demonstration far more striking than any natural phenomena to undeceive the minds of such of the party as were not already in possession of the fatal secret.
Although it was nine o'clock, Cousin Benedict went on talking incessantly, regardless of the fact that one by one his audience were falling to sleep in their separate cells. Dick Sands did not sleep, but neither did he interrupt the entomologist by farther questions; Hercules kept up his attention longer than the rest, but at length he too succumbed to weariness, and his eyes and ears were closed to all external sights and sounds.
