Young Palm-Trees Only Being Employed, They Must Be Planted And Carefully Cultivated.

A little above the mission of Davipe, the Rio Negro receives a branch of the Cassiquiare, the existence of which is a very remarkable phenomenon in the history of the branchings of rivers.

This branch issues from the Cassiquiare, north of Vasiva, bearing the name of the Itinivini; and, after flowing for the length of twenty-five leagues through a flat and almost uninhabited country, it falls into the Rio Negro under the name of the Rio Conorichite. It appeared to me to be more than one hundred and twenty toises broad near its mouth. Although the current of the Conorichite is very rapid, this natural canal abridges by three days the passage from Davipe to Esmeralda. We cannot be surprised at a double communication between the Cassiquiare and the Rio Negro when we recollect that so many of the rivers of America form, as it were, deltas at their confluence with other rivers. Thus the Rio Branco and the Rio Jupura enter by a great number of branches into the Rio Negro and the Amazon. At the confluence of the Jupura there is a much more extraordinary phenomenon. Before this river joins the Amazon, the latter, which is the principal recipient, sends off three branches called Uaranapu, Manhama, and Avateparana, to the Jupura, which is but a tributary stream. The Portuguese astronomer, Ribeiro, has proved this important fact. The Amazon gives waters to the Jupura itself, before it receives that tributary stream.
