THE ROOSEVELT-RONDON SCIENTIFIC EXPEDITION 63 
March 13, and traveling rapidly with the 
current reached the Pimiento Bueno, eighty 
kilometers below, that night. The junction 
of the two rivers forms the Gy Parand. 
The Gy Paranda at its very beginning is a 
mighty river, a thousand yards wide, and 
day by day as we raced with its swirling tor- 
rent we watched its rapid growth until near 
the mouth it reached a breadth of at least 
two miles. The country on both banks is 
heavily forested, and along the upper course 
is inhabited by a tribe of Indians which had 
been absolutely unknown. We were the first 
white men to see them, and they had never 
seen white men before. In appearance they 
differed greatly from their neighbors, the 
Nhambiquara. We met seven, all men, 
and finally induced them to accept gifts of 
beads and knives, in return for which they 
gave us wonderfully decorated arrows six 
feet tall. 
The Gy Parandi abounds in formidable 
rapids, like many South American rivers, and 
we had numerous overland portages, the long- 
est being about three miles, around the falls of 
Sao Vicente. Insects are abundant, and the 
whole region is a vast breeding ground for 
malaria. A number of rubber camps are sit- 
uated on the lower river, the forests being rich 
in hevea. We reached Manaos April 10, 
having stopped at Calama, a station on the 
Madeira, for a short period of collecting. 
As the Ditvida party had not arrived, I 
almost immediately left for the Rio Solimoes 
where several weeks were spent to advantage 
adding to the collections. Among the large 
number of specimens collected were agoutis, 
woolly monkeys, squirrel monkeys, sloths, 
many small rodents and squirrels, all new to 
us; and the complete material for a group of 
hoatzins or lizard-birds was also collected. 
The collections now numbered about fifteen 
hundred birds and about four hundred and 
fifteen mammals, practically all of species 
unknown to us, and some of which are no 
doubt new to science. 
Colonel Roosevelt’s party reached Manaos 
the last day of April, but the story of their 
experiences on the unexplored river is too 
well known to warrant review.
