The commandant of San Pablo d'Olivença assured the adventurer that the authorities were not now absent from Manaos , and he even asked Joam Garral to convey to them his compliments . In all probability the raft would arrive before the town in seven weeks , or a little later , say about the 20th or the 25th of August . The guests of the fazender took leave of the Garral family toward the evening , and the following morning , that of the 3d of July , the jangada recommenced its descent of the river . At noon they passed on the left the mouth of the Yacurupa . This tributary , properly speaking , is a true canal , for it discharges its waters into the Iça , which is itself an affluent of the Amazon . A peculiar phenomenon , for the river displaces itself to feed its own tributaries ! Toward three o'clock in the afternoon the giant raft passed the mouth of the Jandiatuba , which brings its magnificent black waters from the southwest , and discharges them into the main artery by a mouth of four hundred meters in extent , after having watered the territories of the Culino Indians .
