1TI^■EEAKV, XXXV 



Small bark-canoes were here obtamed, and after three days' journey 

 up the Cako and Aruparu, we arrived at the commencement of the 

 trail to Roraima. AVith the exception of the last twenty miles, 

 the whole journey, which occupied forty days, lay through thick forest, 

 " INIount Eoraima (8700 feet) is formed by a sloping base, sur- 

 mounted by a rectangular mass, fifty-four square miles in area, with 

 perpendicular walls 2000 feet in height. On the south-west, part 

 of the wall has slipped and lies diagonally across the face of the upper 

 part of the mountain. By following the ledge so formed the summit 

 can be reached without serious difficulty."
