or bertholletia excelsa), in aromatic pucherks, 

 and in wild cacao trees, forms a point of divi- 

 sion between the waters that flow to the Oroo- 

 noko, the Cassiquiare, and the Rio Negro. The 

 tributary streams on the north, or of the Oroo- 

 noko, are the Mavaca and the Daracapo ; those 

 on the west, or of the Cassiquiare, are the Idapa 

 and the Pacimoni* ; and those on the south, or 

 of the Rio Negro, are the Padaviri and the Caba- 

 buri-^. The latter is divided near it's source 

 into two branches, the westernmost of which is 

 known by the name of Baria;};. The Indians of 

 the mission of San Francisco Solano gave us the 

 most minute descriptions of it's course. It 

 affords the very rare example of a branch, by 

 which an inferior tributary stream, instead of

 a natural channel of efflux, is sometimes dry in very hot 

 summers (Corogr. Bras., vol. ii, p. 554). The upper part of 

 the Cababuri was called Maturaca (Meturacao) 5 the branch 

 which flows into the Pacimoni bears the name of Iminara 

 (Umariuani, Umarynauhy, Umanivari,) and afterward the 

 name of Baria. 



X The waters of the Baria, which is a branch of the Caba- 

 buri, run toward the west, and mingle themselves successively 

 with those of the Pacimoni, the Cassiquiare, and the Rio 

 Negro. As this last river flows toward the east, the waters 

 of the Baria, after a circuit of one hundred and ten leagues, 

 reach the mouth of the Cababuri.
