For an hour the groanings increased. The joists grated on all sides. A struggle was going on in which little by little the trunks were being dragged from their sandy bed.

Toward half-past six cries of joy arose. The jangada floated at last, and the current took it toward the middle of the river, but, in obedience to the cables, it quietly took up its position near the bank at the moment that Padre Passanha gave it his blessing, as if it were a vessel launched into the sea whose destinies are in the hands of the Most High!

CHAPTER X

FROM IQUITOS TO PEVAS

ON THE 6th of June, the very next day, Joam Garral and his people bade good-by to the superintendent and the Indians and negroes who were to stay behind at the fazenda. At six o'clock in the morning the jangada received all its passengers, or rather inhabitants, and each of them took possession of his cabin, or perhaps we had better say his house.

The moment of departure had come. Araujo, the pilot, got into his place at the bow, and the crew, armed with their long poles, went to their proper quarters.

Joam Garral, assisted by Benito and Manoel, superintended the unmooring.

At the command of the pilot the ropes were eased off, and the poles applied to the bank so as to give the jangada a start. The current was not long in seizing it, and coasting the left bank, the islands of Iquitos and Parianta were passed on the right.

The voyage had commenced--where would it finish? In Para, at Belem, eight hundred leagues from this little Peruvian village, if nothing happened to modify the route. How would it finish? That was the secret of the future.

The weather was magnificent. A pleasant _"pampero"_ tempered the ardor of the sun--one of those winds which in June or July come from off the Cordilleras, many hundred leagues away, after having swept across the huge plain of the Sacramento. Had the raft been provided with masts and sails she would have felt the effects of the breeze, and her speed would have been greater; but owing to the sinuosities of the river and its abrupt changes, which they were bound to follow, they had had to renounce such assistance.

In a flat district like that through which the Amazon flows, which is almost a boundless plain, the gradient of the river bed is scarcely perceptible. It has been calculated that between Tabatinga on the Brazilian frontier, and the source of this huge body of water, the difference of level does not exceed a decimeter in each league. There is no other river in the world whose inclination is so slight.

It follows from this that the average speed of the current cannot be estimated at more than two leagues in twenty-four hours, and sometimes, while the droughts are on, it is even less. However, during the period of the floods it has been known to increase to between thirty and forty kilometers.

Happily, it was under these latter conditions that the jangada was to proceed; but, cumbrous in its movements, it could not keep up to the speed of the current which ran past it. There are also to be taken into account the stoppages occasioned by the bends in the river, the numerous islands which had to be rounded, the shoals which had to be avoided, and the hours of halting, which were necessarily lost when the night was too dark to advance securely, so that we cannot allow more than twenty-five kilometers for each twenty-four hours.

In addition, the surface of the water is far from being completely clear. Trees still green, vegetable remains, islets of plants constantly torn from the banks, formed quite a flotilla of fragments carried on by the currents, and were so many obstacles to speedy navigation.

The mouth of the Nanay was soon passed, and lost to sight behind a point on the left bank, which, with its carpet of russet grasses tinted by the sun, formed a ruddy relief to the green forests on the horizon.

The jangada took the center of the stream between the numerous picturesque islands, of which there are a dozen between Iquitos and Pucalppa.
