 having mingled it's waters with those of the 

 Guaviare and the Atabapo, flows toward the 

 north, and passes over the Great Cataracts. 

 All these circumstances are in general well

 Buache no doubt supposed, that in the dif- 

 ferent voyages said to have been performed by 

 water from the Amazon to the Oroonoko, the 

 boats had been dragged over some portage 

 (urastradero) from one stream to another. This 

 respectable geographer might be led so much 

 the more readily to admit, that the rivers had 

 not in nature the course prescribed to them in 

 the new Spanish maps, as these very maps

 ings of confluent streams around lake Parima 

 (that pretended White Sea six hundred leagues
