than this evening scene on the lake, can hardly be conceived. When we reached the landing, the gold and rose-colored clouds were fading into soft masses of white and ashen gray, and moonlight was taking the place of sunset. As we went up the green slope to the sitio, a dance on the grass was proposed, and the Indian girls formed a quadrille; for thus much of outside civilization has crept into their native manners, though they throw into it so much of their own characteristic movements that it loses something of its conventional aspect. Then we returned to the house, where while here and there groups sat about on the ground laughing and talking, and the women smoking with as much enjoyment as the men. Smoking is almost universal among the common women here, nor is it confined to the lower classes. Many a senhora, at least in this part of Brazil, (for one must distinguish between the civilization upon the banks of the Amazons and in the interior, and that in the cities along the coast,) enjoys her pipe while she lounges in her hammock through the heat of the day.
The following day the party broke up. The Indian women came to bid us good by after breakfast, and dispersed in various directions, through the forest paths, to their several homes, going off in little groups, with their babies, of whom there were a goodly number, astride on their hips, and the older children following. Mr. Agassiz passed the morning in packing and arranging his fishes, having collected in these two days more than seventy new species: such is the wealth of life everywhere in these waters. His studies had been the subject of great curiosity to the people about the sitio; one or two were always hovering around to look at his work, and to watch Mr. Bourkhardt's drawing. They seemed to think it extraordinary that any one should care to take the portrait of a fish. The familiarity of these children of the forest with the natural objects about them—plants, birds, insects, fishes—is remarkable. They frequently ask to see the drawings, and, in turning over a pile containing several hundred colored drawings of fish, they will scarcely make a mistake; even the children giving the name instantly, and often adding, "He filho d'elle,"—"It is the child of such a one,"—thus distinguishing the young from the adult, and pointing out their relation. The scientific work excites great wonder among the Indians, wherever we go; and when Mr. Agassiz succeeds in making them understand the value he attaches to his collections, he often finds them efficient assistants.
We dined rather earlier than usual,—our chief dish being a stew of parrots and toucans,—and left the sitio at about five o'clock, in three canoes, the music accompanying us in the smaller boat. Our Indian friends stood on the shore as we left, giving us a farewell greeting with cheers and waving hats and hands. The row through the lake and igarapé was delicious; and we saw many alligators lying lazily about in the quiet water, who seemed to enjoy it, after their fashion, as much as we did. The sun had long set as we issued from the little river, and the Rio Negro, where it opens broadly out into the Amazons, was a sea of silver. The boat with the music presently joined our canoe; and we had a number of the Brazilian modinhas, as they call them,—songs which seem especially adapted for the guitar and moonlight. These modinhas have quite a peculiar character. They are little, graceful, lyrical snatches of song, with a rather melancholy cadence; even those of which the words are gay not being quite free from this undertone of sadness. One hears them constantly sung to the guitar, a favorite instrument with the Brazilians as well as the Indians. This put us all into a somewhat dreamy mood, and we approached the end of our journey rather silently. But as we came toward the landing, we heard the sound of a band of brass instruments, effectually drowning our feeble efforts, and saw a crowded canoe coming towards us. They were the boys from an Indian school in the neighborhood of Manaos, where a certain num-
