leterious juice of the plant. In about half an hour all the smaller fishes, over a rather wide space around the spot, rise to the surface floating on their sides, and with the gills wide open. The poison acts evidently by suffocating the fishes; it spreads slowly in the water, and a very slight mixture seems sufficient to stupify them. I was surprised, on beating the water in places where no fishes were visible in the clear depths for many yards round, to find, sooner or later, sometimes 24 hours afterwards, a considerable number floating dead on the surface.
The people occupy themselves the greater part of the year with their small plantations of mandioca. All the heavy work, such as felling and burning the timber, planting and weeding, is done in the plantation of each family by a congregation of neighbours, which they call a "pucherum:"—a similar custom to the "bee" in the backwood settlements of North America. They make quite a holiday of each pucherum. When the invitation is issued, the family prepares a great quantity of fermented drink, called in this part Tarobá, from soaked mandioca cakes, and porridge of Manicueira. This latter is a kind of sweet mandioca, very different from the Yuca of the Peruvians and Macasheira of the Brazilians (Manihot Aypi), having oblong juicy roots, which become very sweet a few days after they are gathered. With these simple provisions they regale their helpers. The work is certainly done, but after a very rude fashion; all become soddened with Tarobá, and the day finishes often in a drunken brawl.
