I decided eventually to go back upstream and penetrate to the interior in the western part of Guayana, and the Amazonian territory bordering on Colombia and Brazil, and to return to Angostura in about six months' time.

I had no fear of being arrested in the semi-independent and in most part savage region, as the Guayana authorities concerned themselves little enough about the political upheavals at Caracas.
The first five or six months I spent in Guayana, after leaving the city of refuge, were eventful enough to satisfy a moderately adventurous spirit.

A complaisant government employee at Angostura had provided me with a passport, in which it was set down (for few to read) that my object in visiting the interior was to collect information concerning the native tribes, the vegetable products of the country, and other knowledge which would be of advantage to the Republic; and the authorities were requested to afford me protection and assist me in my pursuits.

I ascended the Orinoco, making occasional expeditions to the small Christian settlements in the neighbourhood of the right bank, also to the Indian villages; and travelling in this way, seeing and learning much, in about three months I reached the River Metal.

During this period I amused myself by keeping a journal, a record of personal adventures, impressions of the country and people, both semi-civilized and savage; and as my journal grew, I began to think that on my return at some future time to Caracas, it might prove useful and interesting to the public, and also procure me fame; which thought proved pleasurable and a great incentive, so that I began to observe things more narrowly and to study expression.
