ntering into some highway
river, was mere guess-work, he had entered it on his sketch maps as
the Rio da Duvida, the River of Doubt. Among the officers of the
Brazilian Army and the scientific civilians who have accompanied him
there have been not only expert cartographers, photographers, and
telegraphists, but astronomers, geologists, botanists, and zoologists.
Their reports, published in excellent shape by the Brazilian
Government, make an invaluable series of volumes, reflecting the
highest credit on the explorers, and on the government itself. Colonel
Rondon's own accounts of his explorations, of the Indian tribes he has
visited, and of the beautiful and wonderful things he has seen,
possess a peculiar interest.

V. UP THE RIVER OF TAPIRS

After leaving Caceres we went up the Sepotuba, which in the local
Indian dialect means River of Tapirs. This river is only navigable for
boats of size when the water is high. It is a swift, fairly clear
stream, rushing down from the Plan Alto, the high uplands, through the
tropical lowland forest. On the right hand, or western bank, and here
and there on the left bank, the forest is broken by natural pastures
and meadows, and at one of these places, known as Porto Campo, sixty
or seventy miles above the mouth, there is a good-sized cattle-ranch.
Here we halted, because the launch, and the two pranchas--native
trading-boats with houses on their decks--which it towed, could not
carry our entire party and outfit. Accordingly most of the baggage and
some of the party were sent ahead to where we were to meet our pack-
train, at Tapirapoan. Meanwhile the rest of us made our first camp
under tents at Porto Campo, to wait the return of the boats. The tents
were placed in a line, with the tent of Colonel Rondon and the tent in
which Kermit and I slept, in the middle, beside one another. In front
of these two, on tall poles, stood the Brazilian and American flags;
and at sunrise and sunset the flags were hoisted and hauled down while
the trumpet sounded and all of us stood at attention. Camp was pitched
beside the ranch buildings. In the trees near the tents grew wonderful
violet orchids.

Many birds were around us; I saw some of them, and Cherrie and Miller
many, many more. They ranged from party-colored macaws, green parrots,
and big gregarious cuckoos down to a brilliant green-and-chestnut
kingfisher, five and a quarter inches long, and a tiny orange-and-
