The beginning of June was the best season to start, for the waters, increased by the floods of the upper basin, would gradually and gradually subside until the month of October.
The first steps had thus to be taken without delay, for the raft was to be of unusual proportions.

It would be necessary to fell a half-mile square of the forest which was situated at the junction of the Nanay and the Amazon--that is to say, the whole river side of the fazenda, to form the enormous mass, for such were the _jangadas,_ or river rafts, which attained the dimensions of a small island.
It was in this _jangada,_ safer than any other vessel of the country, larger than a hundred _egariteas_ or _vigilingas_ coupled together, that Joam Garral proposed to embark with his family, his servants, and his merchandise.
"Excellent idea!" had cried Minha, clapping her hands, when she learned her father's scheme.
"Yes," said Yaquita, "and in that way we shall reach Belem without danger or fatigue." "And during the stoppages we can have some hunting in the forests which line the banks," added Benito.
"Won't it take rather long ?" observed Manoel; "could we not hit upon some quicker way of descending the Amazon ?" It would take some time, obviously, but the interested observation of the young doctor received no attention from any one.
Joam Garral then called in an Indian who was the principal manager of the fazenda.
"In a month," he said to him, "the jangada must be built and ready to launch." "We'll set to work this very day, sir." It was a heavy task.

There were about a hundred Indians and blacks, and during the first fortnight in May they did wonders.

Some people unaccustomed to these great tree massacres would perhaps have groaned to see giants many hundred years old fall in a few hours beneath the axes of the woodmen; but there was such a quantity on the banks of the river, up stream and down stream, even to the most distant points of the horizon, that the felling of this half-mile of forest would scarcely leave an appreciable void.
The superintendent of the men, after receiving the instructions of Joam Garral, had first cleared the ground of the creepers, brushwood, weeds, and arborescent plants which obstructed it.

Before taking to the saw and the ax they had armed themselves with a felling-sword, that indispensable tool of every one who desires to penetrate the Amazonian forests, a large blade slightly curved, wide and flat, and two or three feet long, and strongly handled, which the natives wield with consummate address.
