 and visited afterwards a village in latitude 12 min. 

 south. They had thus crossed the equator at noon, 

 and had so far accomplished one of the objects of 

 the expedition. 



Immediately on returning to the boats, they 

 started on their further ascent of the Essequibo. 

 The river flows through a rich mountain valley, but 

 is narrowed to fifteen yards, and was much ob- 

 structed by trees which had fallen across it. During 

 the first two days, the rapidity of the current was

 they arrived at one of the sources of the Essequibo, 

 at a spot surrounded by high trees interwoven with 

 lianas, so much so that no sight could be got of
