On first arriving here, the inharmonious sounds which begin to annoy the ear about Avi Maria, sent forth by field-crickets, frogs, toads, and other reptiles, are quite alarming to a stranger, who anticipates at every step, if he walks into a shacara, to encounter some venomous creature. It is custom alone that reconciles this loud, unceasing, nocturnal clamour. Lizards are very numerous, some of a green colour. They are timid, and are constantly seen running across the roads, up walls, or rustling amongst the hedges. The vampire-bat is very large here, and if they can get access to the stables will fix upon a horse, and suck the blood. I have seen the back of a horse quite saturated with it, in consequence of a bite from one of them. They are said to fan their wings, during this sanguinary proceeding, in order to assuage the pain which their bite creates. It is supposed that they would fix upon the human body in the same way; and this is probable, from the following circumstance. In consequence of the excessive heat, I was in the habit of leaving open the shutter of my bed-room. One evening I discovered a vampire-bat, as large as two hands, upon the bed-post, and, by a blow, stunned it, so that it could not escape by the window, but secreted itself in the room. During the night it got twice upon the bed, but the heat preventing a sound sleep, I was quickly awakened by its attempts. It is too well known, perhaps, to remark that the Brazil is not the seat of literature; in fact, its total absence is marked by the prohibition of books generally, and the want of any single medium through which its inhabitants can attain even to a knowledge of the existing state of the world, or what is passing in it. The inhabitants are principally involved in great ignorance and pride, its usual consequence; an acquirement of the modes and ceremonies attached to the pompous observance of their religion appearing to be deemed quite adequate to all the purposes of the present system of society. A liberal literary institution of any kind throughout the state, or a stimulus to a man of talent, would be looked for in vain. A gazette, published twice a week, is printed at the royal press, the only one established here; but it affords to the people no intelligence of the state of their own country or that of others. It is the size of a sheet of small letter-paper, and is filled with the arrivals and departures of vessels, and some advertisements, while occasionally two or three heads are extracted with caution from the English newspapers. In the whole of the Brazil there is only one other gazette, and that is published at Bahia. Its neighbouring colony of Spanish South America has already begun to dispel the ignorance in which it was alike enveloped, by the establishment of several public colleges in different places, and the liberal and free introduction of books, which will fast promote the spirit of learning that partially begins to dawn.
