of rock spread all across the river, while through the openings between them the water rushed with terrific violence, forming dangerous whirlpools and breakers below. Here it was neces- sary to cross to the other side, in order to get up. We dashed into the current, were rapidly carried down, got among the boiling waves, then passed suddenly into still water under shelter of an island; whence starting again, we at length reached the other side, about a mile across. Here we found ourselves at the foot of a great rush of water, and we all got out upon the rocks, while the Indians, with a strong rope, partly in the water, and partly on land, pulled the canoe up, and we again proceeded. As we went on we constantly encountered fresh difficulties. Sometimes we had to cross into the middle of the stream, to avoid some impassable mass of rocks ; at others, the canoe was dragged and pushed in narrow channels, which hardly allowed'it to pass. The Indians, all naked, with their trousers tied round their loins, plunged about in the water like fishes. Sometimes a projecting crag had to be reached with the tow-rope. An Indian takes it in his hand, and leaps into the rapid current : he is carried down by its irresistible force. Now he dives to the bottom, and there swims and crawls along where the stream has less power. .After two or three trials he reaches the rock, and tries to mount upon it ; but it rises high and abruptly out of the water, and after several efforts he falls back exhausted, and floats down again to the canoe amid the mirth and laughter of his comrades. Another now tries, with the same result. Then another plunges in without the rope, and thus unen- cumbered mounts on the rock and gives a helping hand to his companion ; and then all go to work, and we are pulled up past the obstacle.
But a little ahead of us is an extensive mass of rocks. There is no passage for the canoe, and we must cross to yonder islet far in the middle of the stream, where, by the height of the water, Senhor L. and the pilot judge we shall find a passage. Every stone, even those under water, form eddies or returning currents, where a canoe can rest in its passage. Off we go, to try to reach one of them. In a moment we are in a stream running like a mill-race. " Pull away, boys ! " shouts Senhor L. We are falling swiftly down the river. There is a strong rapid carrying us, and we shall be dashed against those black
