I also had long conversations with General Ballivian, ex-President of Bolivia, then an exile to Chili. He lent me a map of Bolivia, executed under his orders whilst President of that republic, of which I took a tracing, but which I had afterwards the misfortune to lose.

At Santiago I received information regarding the river Beni, and the interior of Bolivia and Peru, from a French gentleman named Pissis, an engineer in the employment of the Chilian government; and also from a gentleman named Smith, an employé in the large mercantile house of Huth, Gruning & Co., who had travelled much in those countries.

To Don José Pardo, chargé d'affaires of Peru to the republic of Chili, I owe much for information and advice. He gave me copies of letters from Vicente Pazos, a citizen of Buenos Ayres, who has always manifested much interest in the improvement and advancement of South America, and who, in 1819, published a series of papers on the affairs of that country, directed to Henry Clay. These letters I deem of sufficient interest to give a translation of.

Buenos Ayres, July 14, 1850.

To Don Jose Pardo,
Minister of the Peruvian Republic, near the Government of Chili.

Sir: In a journal of this capital of the 2d inst., I have seen a transcript of a letter from you to the editor of a periodical of this place, in which you say, under date of the 25th of April last, that you have received special notice of the discovery, in the province of "Carabaya," of the ore and washings of gold. In consequence, the government of Peru invites all who desire it to take advantage, and make use of the natural productions of these regions, where emigrants of all nations shall have all the political and religious guarantees necessary in the exercise of their industry.

This announcement fills me with pleasure, because it is an evidence of the elevation of ideas which obtains in the government, and which will carry this part of Upper Peru to the height of prosperity to which it is called by its topographical and territorial position; and particularly because it has in its midst navigable rivers which connect it with the Atlantic. I allude to the navigation of the Amazon.

I have been now engaged some ten years in the thought and study of the political, social, and commercial relations concerning this matter, as is shown in my many publications which have circulated in Europe and America. These show the pains I have taken with the government of Louis Philippe, King of France, in order to open a new line of commercial communication between Cayenne and French Guyana and the republics of Peru, Bolivia, Ecuador, and Venezuela.

But I have always thought that our America, by the intelligence of its people, was to make a great social and commercial change; and I have always thought that this change would operate by means of its gigantic and navigable rivers. This conception is corroborated by the announcement of the discovery of the gold regions of Carabaya. Its upper parts, which belong to the Andes, feed sheep of the most exquisite wool; and as it goes on descending, vegetation springs up with a fecundity and ease unknown in the Old World. The land is cut up with mountain torrents, whose banks contain gold, and which unite to form the river "Purus," one of the greatest tributaries of the Amazon.

Of this river, our celebrated botanist, D. Tadeo Há-enke, in a special report, says: "Purus, or Cachivara, is a river of the first order. It arises in the cordillera of Vilcanota, a little to the east of the mountains of Carabaya, from which descend many considerable streams, rich in gold." To the testimony of this wise naturalist I add that of Condamine, and of the English naval officer, Smyth, and lastly the works of the Count of Castelnau, who descended the Amazon from Cuzco.
