 and the boats, on account of the want of watery

 on the west and east the mountains of Guanaya 

 and Yumariquin, where the bertholletias (ches-

 distant is the mouth of the Gehette, where there 

 is a great cataract. A dyke of granitic rocks 

 crosses the Oroonoko ; these rocks are the 

 columns of Hercules, beyond which no white 

 man has been able to penetrate. It appears, that
