THE FALLS OF THE YGUASSU. 



Thirteen miles above the confluence with the Parana. Like the Parana at the Salto 

 Guayra, the river cuts through a layer of basalt intercalated in the red sandstone. The 

 forest of the province of Misiones has a tropical character near the river. The araucarias 

 cover only the higher parts of the tableland.
