icker, and were filled almost
entirely with yellow, having very little albumen. We all set to work to
hunt for more, and were fortunate in finding another nest, the eggs
being a welcome addition to our scanty supply of food. The Indians
meantime, while we were finishing breakfast, set off into the forest,
and just as we were ready to start came back with another iguana.

We were constantly employed in trying to teach Duppo English. Arthur
was explaining to him the animals of our country, and was mentioning the
cow, and describing its milk. He seemed much interested, and then gave
us to understand that they also had cows in their land, which, instead
of walking about on four legs, grew in the ground, and were of great
size. After this he was constantly looking out along the banks, and at
length he shouted out to the men, "Massaranduba!" and they at once
paddled in for the bank. One of them accompanied us with an axe. As we
passed along we found on the ground a number of woody vessels, which had
evidently contained seeds. Duppo picked up one of them, and found
another piece close by which fitted on to it, and then told us that they
were called monkeys' drinking-cups; the Portuguese call them _cuyas de
macaco_. These shells had contained nuts. When falling off the tree--
the sapucaya--the tops split off, and the nuts are scattered on the
ground. Duppo made us understand that these cups would serve well to
collect the milk from the cow he promised to show us.

I may observe that the trees which bear the monkey drinking-cups are
closely allied to the Brazil-nut tree, the fruit of which we had often
seen sold in England under that name. Its seeds are also enclosed in
large woody vessels, but they, having no lid, fall entire to the ground,
and are thus easily collected by the natives.

Supplied with these vessels, we went on a few yards further, when we
stopped under an enormous tree, one of the giants of the forest. Its
trunk was covered with deeply scored reddish and rugged bark. Duppo
patted it, saying, "This my cow." Another tree of the same species, but
much smaller, grew near. He ran to it, and saying, "Small cow give
better milk," began to attack it with his axe. After making a few
strokes, out flowed a perfectly white liquid, which John, kneeling down,
caught in the monkey-cup. As soon as it was filled I handed him
another, the milk continuing to flow in great abundance, so that we soon
had four cup
