Lower Guainia, signifies also black water*. The 

 junction of the Guainia or Rio Negro with the 

 Amazon is considered of such importance in the 

 government of Grand Para, that the Rio das

 nation of the Sorimans). The Amazon, to the

 account of their very purity) furnish less aliment 

 to aquatic insects and fish. Notwithstanding 

 this scarcity, the Indians of these countries, dur-
