278 THROUGH THE BRAZILIAN WILDERNESS 



system and drainage basin. The rubber-gatherers reported 

 that they had gone many days' journey up the river, to a 

 point where there was a series of heavy rapids with above 

 them the junction-point of two large rivers, one entering 

 from the west. Beyond this they had difficulties because 

 of the hostility of the Indians; and where the junction-

 it the Rio Roosevelt. This was a complete surprise to me. 

 Both Lauro Muller and Colonel Rondon had spoken to me 

 on the subject, and I had urged, and Kermit had urged, as 

 strongly as possible that the name be kept as Rio da Du-
