 gions, and of the lofty mountains of the tropics. 



After having passed the little forts of Vieja 

 Guayana, the bed of the Orconoko again widens. 

 The state of cultivation of the country on the 

 two banks affords a striking contrast. On the

 The last of these villages, situate on the banks of
