Bats are so numerous in the city that they cover the streets in an evening in clouds, and there is not a house in which these nocturnal birds are not found. Of these the most formidable is the vampyre, which, according to the authority of Ulloa and other travellers, has been known to suck the blood of a sleeping person, at the same time fanning its victim with its broad wings. The insects and reptiles peculiar to the climate are as numerous as the birds and beasts. Of these the centipede, the scorpion, the spider; and amongst the serpents, the rattle snake, the dart, and the dreadful corales, or coral snakes, are the most venomous, the bite of the latter being rarely cured. Whilst the feet of the pedestrian are insecure from the attacks of these dreadful creatures, his face is exposed to the venom of the mosquitoes, which attain a great size, and are exceeding troublesome. The beds of the inhabitants of Carthagena are surrounded with gauze curtains to protect the sleeper from these insects, but this is unavailing; for another and almost imperceptible enemy creeps in through the threads, and annoys any part of the body which may be exposed; these are called manta blancas, or white cloaks (by their forming a cloud in the air of that colour); they cause no other pain than an intolerable itching. The pique is also another disagreeable insect of this country, which penetrates the skin of the feet or hands, and causes intolerable pain; this animal it well known in the West Indies under the name of jigger, or chigoe. Goods which belong to the merchants of Carthagena are frequently destroyed in a short time by a sort of moth, which perforates, in a single night, through and through the finest bales of cloth, linen, silks or laces; the only way they have of preventing this is to place them on benches away from the walls, and to smear the feet or supports with naptha. The country produces neither wheat nor barley, but maize and rice in great plenty. Of the maize they form a kind of bread called bollo, which is used by the natives and Europeans; the negroes make greater use of the cassava bread, made from roots; in fact it is their chief food; whilst the opulent families use the flour of European wheat, imported from Spain. Sugar-cane plantations are very common, and rum is distilled in small quantities. The cotton-tree is cultivated, and the cacao of Carthagena is said to excel that of the Caraccas, both in its size and goodness.
