the
field with their men, and each can raise about forty, able to carry
arms. A few of these Indians have gnns of their own, which they use in
hunting, and their powder is a coarse kind, manufactured by themselves.
Some of the shopkeepers in the towns to the south-west, every year go
down by the Rio Tocantins to Para to sell hides and purchase European
goods; very frequently some of the young men belonging to Duro
hire themselves to work the canoes, and with the money wliich they
receive for their services, purchase at Para axes and other iron tools;
a party of them returned from one of these trips during our visit.
During

suffering from ophthalmia. I, of
