232 MOSQUITOES INDIANS. 



rock, the Piedra di Culimacari, which they found to 

 be in lat. 2 0' 42" north, and long. 67 13' 26" west. 

 The determination was of great importance in a 

 geographical and political point of view, for the 

 greatest errors existed in maps, and the equator had 

 been considered as the boundary between the Spanish 

 and Portuguese possessions. 



Leaving the Rock of Culimacari at half after one 

 in the morning, they proceeded against the current, 

 which was very rapid. The waters of the Casi-
