Abstract
AT a special meeting of the Royal Geographical Society on Tuesday, June 16, Mr. Roosevelt gave an account of his recent journey in Central Brazil. In his opening remarks he alluded to the excellent work of the Telegraphic Commission under Col. Rondon in exploring the sandstone plateau which, under different names, extends west-north-west through northern Matto Grosso towards the cataracts of the Rio Madeira, and separates the drainage basins of the Paraguay and the Guaporé from those of the Xingu, Tapajos, and some of the tributaries of the Madeira. To the west of the affluents of the Juruena, the western fork of the Tapajos, they met with two considerable streams which they named the Ananaz and the Duvida; the ultimate courses of these were uncertain, hence the name, meaning “doubt” given to the latter. Beyond was another stream, which was descended and demonstrated to be the Gi-paraná, which enters the Madeira a little below San Antonio.
