“Desirous of ascertaining the natural food of the scorpion, I inclosed one (which measured three-quarters of an inch from the head to the insertion of the tail) in a wide-mouthed phial, together with one of those large spiders so common in the West Indies, and closed it with a cork, perforated by a quill for the admission of air. The insects seemed carefully to avoid each other, retiring to opposite ends of the bottle, which was placed horizontally. By giving it a gradual inclination, the scorpion was forced into contact with the spider, when a sharp encounter took place, the latter receiving repeated stings from his venomous adversary, apparently without the least injury; while, with his web, he soon lashed the scorpion’s tail to his back, and afterwards secured his legs and claws with the same materials. In this state I left them some time, in order to observe what effect would be produced on the spider, by the wounds he had received. On my return, however, I was disappointed, the ants having entered, and destroyed them both.
“In the West Indies I have daily witnessed crowds of these little insects destroying the spider or cockroach, which, as soon as he is dispatched, they carry to their nest. I have frequently seen them drag their prey perpendicularly up the wall, and, although the weight would overcome their united efforts, and fall to the ground, perhaps twenty times in succession, yet, by unremitting perseverance, and the aid of reinforcements, they always succeeded.
“A struggle of this description once amused the officers of his majesty’s ship Retribution, for nearly half an hour: a large centipede entered the gun-room, surrounded by an immense concourse of ants; the deck, for four or five feet round, was covered with them; his body and limbs were encrusted with his lilliputian enemies; and although thousands were destroyed by his exertions to escape, they ultimately carried him in triumph to their dwelling.
“In the woods near Sierra Leone, I have several times seen the entire skeletons of the snake beautifully dissected by these minute anatomists.”
From these circumstances it would appear, that ants are a considerable check to the increase of those venomous reptiles, so troublesome in the torrid zone; and their industry, perseverance, courage, and numerical force, seem to strengthen the conjecture: in which case they amply remunerate us for their own depredations.
