At length, after a prolonged voyage of 28 days, we reached Santarem, at the mouth of the river Tapajoz, whose blue, transparent waters formed a most pleasing contrast to the turbid stream of the Amazon. We stayed at Santarem during September, October, and November, working hard till three in the afternoon each day, generally collecting some new and interesting insects in the forest. Here was the haunt of the beautiful "Callithea sapphirs," one of the most lovely of butterflies, and of numerous brilliant little "Erycinidæ."
The constant exercise, pure air, and good living, notwithstanding the intense heat, kept us in the most perfect health, and I have never altogether enjoyed myself so much.
V.—The City of Barra
On December 31, 1849, we arrived at the city of Barra on the Rio Negro. It is situated on the east bank of that tributary, about twelve miles above its junction with the Amazon. The trade is chiefly in Brazil nuts, sarsaparilla, and fish. The distance up the Amazon from Pará to Barra is about 1,000 miles. The voyage often occupies from two to three months. The more civilized inhabitants of the city are all engaged in trade, and have literally no amusements whatever, unless drinking and gambling on a small scale can be so considered: most of them never open a book, or have any mental occupation.
The Rio Negro well deserves its name—"inky black." For its waters, where deep, are of dense blackness. There are striking differences between this river and the Amazon. Here are no islands of floating grass, no logs and uprooted trees, with their cargoes of gulls, scarcely any stream, and few signs of life in the black and sluggish waters. Yet when there is a storm, there are greater and more dangerous waves than on the Amazon. At Barra the Rio Negro is a mile and a half wide. A few miles up it widens considerably, in many places forming deep bays eight or ten miles across.
In this region are found the umbrella birds. One evening a specimen was brought me by a hunter. This singular bird is about the size of a raven. On its head it bears a crest, different from that of any other bird. It can be laid back so as to be hardly visible, or can be erected and spread out on every side, forming a hemispherical dome, completely covering the head. In a month I obtained 25 specimens of the umbrella bird.
The river Uaupés is a tributary of the Upper Rio Negro, and a voyage up this stream brought us into singular regions. Our canoe was worked by Indians. In one of the Indian villages we witnessed a grand snake dance. The dancers were entirely unclad, but were painted in all kinds of curious designs, and the male performers wear on the top of the head a fine broad plume of the tail-coverts of the white egret. The Indians keep these noble birds in great open houses or cages; but as the birds are rare, and the young with difficulty secured, the ornament is one that few possess. Cords of monkeys' hair, decorated with small feathers, hang down the back, and in the ears are the little downy plumes, forming altogether a most imposing and elegant headdress.
The paint with which both men and women decorate their bodies has a very neat effect, and gives them almost the aspect of being dressed, and as such they seem to regard it. The dancers had made two huge artificial snakes of twigs and branches bound together, from thirty to forty feet long and a foot in diameter, painted a bright red colour. This made altogether a very formidable looking animal. They divided themselves into two parties of about a dozen each and, lifting the snake on their shoulders, began dancing.
In the dance they imitated the undulations of the serpent, raising the head and twisting the tail. In the manœuvres which followed, the two great snakes seemed to fight, till the dance, which had greatly pleased all the spectators, was concluded.
