Who doubts that a mosquito will perch itself upon the skin of a human being, pierce it with his proboscis, and suck away until it is gorged with blood? Why does it appear strange that a bat should do the same?
Now your closet-naturalist will believe that the bat does suck the blood of cattle and horses, but denies that it will attack man! This is sheer nonsense. What difference to the vampire, whether its victim be a biped or quadruped? Is it fear of the former that would prevent it from attacking him? Perhaps it may never have seen a human being before: besides, it attacks its victim while asleep, and is rarely ever caught or punished in the act. Where these creatures are much hunted or persecuted by man, they may learn to fear him, and their original habits may become changed, but that is quite another thing. As nature has formed them, the blood-sucking bats will make their attack indifferently, either upon man or large quadrupeds. There are a thousand proofs to be had in all the tropical regions of America. Every year animals are killed by the phyllostoma hastatum, not in hundreds, but in thousands. It is recorded that on one extensive cattle-farm several hundred head were killed in the short period of six months by the bats; and the vaqueros, who received a bounty upon every bat they should capture, in one year succeeded in destroying the enormous number of seven thousand! Indeed, “bat-hunting” is followed by some as a profession, so eager are the owners of the cattle-farms to get rid of these pests.
Many tribes of Indians and travellers suffer great annoyance from the vampire-bats. Some persons never go to sleep without covering themselves with blankets, although the heat be ever so oppressive. Any part left naked will be attacked by the phyllostoma, but they seem to have a preference for the tip of the great toe—perhaps because they have found that part more habitually exposed. Sometimes one sleeper is “cupped” by them, while another will not be molested; and this, I may observe, is true also of the mosquitoes. There may be some difference as to the state of the blood of two individuals, that leads to this fastidious preference. Some are far more subject to their attack than others—so much so that they require to adopt every precaution to save themselves from being bled to death. Cayenne pepper rubbed over the skin is used to keep them off, and also to cure the wound they have made; but even this sometimes proves ineffective.
Of course there are many species of bats in South America besides the vampire; in fact, there is no class of mammalia more numerous in genera and species, and no part of the world where greater numbers are found than in the tropical regions of America. Some are insect-eaters, while others live entirely on vegetable substances; but all have the same unsightly and repulsive appearance. The odour of some kinds is extremely fetid and disagreeable. Notwithstanding this, they are eaten by many tribes of Indians, and even the French Creoles of Guiana have their “bat-soup,” which they relish highly. The proverb “De gustibus non disputandum est” seems to be true for all time. The Spanish Americans have it in the phrase “Cada uno a su gusto;” “Chacun à son goût,” say the French; and on hearing these tales about “ant-paste,” and “roast monkey,” and “armadillo done in the shell,” and “bat-soup,” you, boy reader, will not fail to exclaim “Every one to his liking.”
The vampire appeared to be to Guapo’s liking. It was now his turn to keep watch, and as the rest of them got into their hammocks, and lay awake for a while, they saw him take up the bat, spit it upon a forked stick, and commence broiling it over the fire. Of course he ate it!
When morning came, and they had got up, what was their astonishment to see no less than fourteen bats lying side by side! They were dead, of course: Guapo had killed them all during his watch. They had appeared at one period of the night in alarming numbers, and Guapo had done battle manfully without awaking anybody.
Another curious tableau came under their notice shortly after. Just as they were about to embark, a singular-looking tree was observed growing near the bank of the river. At first they thought the tree was covered with birds’-nests, or pieces of some kind of moss. Indeed, it looked more like a tree hung over with rags than anything else. Curiosity led them to approach it. What was their astonishment to find that the nests, moss, or rags, were neither more nor less than a vast assemblage of bats suspended, and asleep! They were hanging in all possible positions; some with their heads down, some by the claws upon either wing, and some by both, while a great many had merely hooked over the branch the little horny curvature of their tails. Some hung down along the trunk, suspended by a crack in the bark, while others were far out upon the branches.
It was certainly the oddest “roost” that any of the party (Guapo, perhaps, excepted) had ever witnessed; and, after gazing at it for some time, they turned away without disturbing the sleepers, and getting on board once more, floated adown the stream swiftly and silently.
