The manatee ranges from the mouth of the Amazon to the upper waters. It feeds on the grass growing on the borders of the lakes and rivers. It swims at a rapid rate, moved by the tail and paddles. The creature is hunted and killed by the natives with harpoons, the flesh being much sought after. The taste is somewhat between that of pork and beef. The natives dress it by cutting the meat into small pieces and sticking them on skewers, which they place in a slanting position over the flames to roast. The female produces one, though sometimes two at a birth, which she holds in her paddles while giving suck. From twenty to twenty-five gallons of oil are obtained from each sea-cow. The poor manatee, little able to defend itself, has other enemies besides man. The jaguar lies in wait for it on the trunk of a tree overhanging the placid pool, and seizing it with his powerful claws as it swims by, holds it in a vice-like grasp, from which in spite of its strength it in vain endeavours to escape. Those who have voyaged on the ocean, know the solemn feeling and the idea of vastness which is conveyed during a calm at night, when monsters of the deep are heard far and near as they come to the surface to inhale the air, or "blow," as it is called. The same feeling is experienced by the traveller up the Amazon when on board his montaria at anchor, when he hears the splashing and snorting sounds of its numerous inhabitants, as they rise through the mirror-like plain, in which countless thousands of bright stars are reflected. Here fresh-water dolphins roam in great numbers. In the Lower Amazon are two species; one of which,--the tucuxi,--when it comes to the surface to breathe, rises horizontally, showing first the back of its fin, and then, drawing an inspiration, generally diving down head-foremost; and another, called the bonto by the natives. When it rises, it first shows the top of the head, and then floating onwards, immediately afterwards dips its head downwards, its back curving over--exposing successively the whole dorsal ridge without showing the tail-fin; the well-known mode in which the sea-porpoise swims, which makes it appear to pitch head over heels. The natives regard the bonto or largest species with especial awe, and will never kill one voluntarily. Though their fat yields an excellent oil for lamps, they believe that blindness would result from its use. The bonto is supposed to possess the characteristic of the malign water-nymphs of the Old World. They have a legend that a bonto was in the custom of assuming the shape of a beautiful woman, with hair hanging loose down to her heels; who, going on shore, endeavoured to entice young men to the river. When any unhappy youth, smitten with her charms, was induced to follow her to the water's edge, she would grasp her victim round the waist, and plunging beneath the waves with a triumphant shriek, disappeared with him for ever.
