Resumothree days longer to reach the Commemoracao.The spot was called Barao de MelgaQo, and marked practically the end of the telegraph line.The trip from Tapirapoan to the Commemoracao had required exactly 40 days; the distance is approximately 548 miles.Many of the pack animals were in such poor condition that they had to be shot.It is impossible to say how many had been lost on the way, but the number was very large.Barao de Melga(.loseemed to be the headquarters of annoying insects and disease.Most of the handful of men at work on the telegraph line were ill with fever and beriberi, and there had been twelve deaths just before our arrival.We had expected to find canoes awaiting us, but as there were none, the men cut down a tree of ample size and began making one.This work, we estimated, would require a month; but after a wait of two weeks a large canoe arrived from down the river.The time at Barao de Melga(.lo was profitably if not pleasantly spent.All about the little clearing rose the stately Amazonian forest, providing admirable collecting grounds.Many birds and mammals were taken, all new to the eollceiion.'1'he latter included an un describable spider monkey and a saki17 of a new genus.We started down the Commemoracao March 13th, and traveling rapidly with the curren' t reached the Pimiento Bueno, 80 kilometers below, that night.The junction of the two rivers forms the Gy Parana.The Gy Parana at its very beginning is a mighty river, a thousand yards wide, and day by day as we raced with its swirling torrent 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 be fore.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 Parana abounds in formidable rapids, like"Saki: a South American monkey with a hushy tail a nd a rull' of long hair around the face.many South American rivers, and we had numerous over land portages, the longest 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 situated on the lower river, the forests being rich in hevea.We reached Manaos April 10th, having stopped at Calama, a station on the Madeira, for a short period of collecting.As the Duvida party had not arrived, I almost im mediately 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, aU new to us; and the complete material for a group of hoatzins or lizard-birds was also collected.The collections now numbered about 1,500 birds and about 415 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.
