Then there opened out the mouth of the Rio Trombetas, bathing with its black waters the houses of Obidos, situated at about one hundred and eighty miles from Belem, quite a small town, and even a “citade” with large streets bordered with handsome habitations, and a great center for cocoa produce. Then they saw another tributary, the Tapajos, with its greenish-gray waters descending from the south-west; and then Santarem, a wealthy town of not less than five thousand inhabitants, Indians for the most part, whose nearest houses were built on the vast beach of white sand.

After its departure from Manaos the jangada did not stop anywhere as it passed down the much less encumbered course of the Amazon. Day and night it moved along under the vigilant care of its trusty pilot; no more stoppages either for the gratification of the passengers or for business purposes. Unceasingly it progressed, and the end rapidly grew nearer.

On leaving Alemquer, situated on the left bank, a new horizon appeared in view. In place of the curtain of forests which had shut them in up to then, our friends beheld a foreground of hills, whose undulations could be easily descried, and beyond them the faint summits of veritable mountains vandyked across the distant depth of sky. Neither Yaquita, nor her daughter, nor Lina, nor old Cybele, had ever seen anything like this.

But in this jurisdiction of Para, Manoel was at home, and he could tell them the names of the double chain which gradually narrowed the valley of the huge river.

“To the right,” said he, “that is the Sierra de Paracuarta, which curves in a half-circle to the south! To the left, that is the Sierra de Curuva, of which we have already passed the first outposts.”

“Then they close in?” asked Fragoso.

“They close in!” replied Manoel.

And the two young men seemed to understand each other, for the same slight but significant nodding of the head accompanied the question and reply.

At last, notwithstanding the tide, which since leaving Obidos had begun to be felt, and which somewhat checked the progress of the raft, the town of Monto Alegre was passed, then that of Pravnha de Onteiro, then the mouth of the Xingu, frequented by Yurumas Indians, whose principal industry consists in preparing their enemies’ heads for natural history cabinets.

To what a superb size the Amazon had now developed as already this monarch of rivers gave signs of opening out like a sea! Plants from eight to ten feet high clustered along the beach, and bordered it with a forest of reeds. Porto de Mos, Boa Vista, and Gurupa, whose prosperity is on the decline, were soon among the places left in the rear.
