"Mr. Uville, who is now about thirty-six years of age, came to England in 1811, where he continued a few months, and just as he was about to leave London he observed by accident a model of a steam-engine, made by Captain Trevithick, at the shop of a Mr. Roland, Fitzroy Square, and Mr. Uville so much liked the simplicity of its construction, that he immediately purchased it at twenty guineas. Mr. Uville returned to Lima with it, and tried it on the mountains of Pasco, in consequence of which, on the 17th of July, 1812, Mr. Uville, with Don Pedro Abadia and Don José Aresmendi, eminent merchants at Lima, were so confident of success, that they formed a company to drain the mines at Pasco and its vicinity; and on the 22nd of August then following a contract was entered into by these gentlemen and the proprietors of the mines in that district. Soon after which Mr. Uville was deputed by the company to return to England and to find out some able engineer to assist him in procuring proper steam-engines to be conveyed to the mines. "Uville having put into Jamaica, came to England in the 'Fox' packet, Capt. Tilly, and arrived at Falmouth early in the summer of 1813. During the passage Mr. Uville frequently talked of the object of his voyage, and that he was particularly anxious to find out the maker of the model of the engine he took to Lima, and recollecting that the name of 'Trevithick' was on the model, he mentioned it to a Mr. Teague, who happened to be on board the packet, when the latter informed him that Capt. Trevithick was his first cousin, and that he resided within a few miles from Falmouth. Immediately on Mr. Uville's arrival an interview took place between him and Capt. Trevithick, and soon after Mr. Uville removed to Capt. Trevithick's house in Camborne, where he resided several months, during which time Capt. Trevithick instructed him in mining, machinery, &c. "Capt. Trevithick and Mr. Uville, after seeing most of the mines in Cornwall, visited several other mining districts in England, to afford Mr. Uville a better opportunity of acquiring the best knowledge of engineering by examining the steam-engines erected. Afterwards they went to London, when Mr. Uville was introduced to a Mr. Campbell, of the East India Company's department. Mr. Campbell informed Mr. Uville that the best engineers in Europe were Messrs. Boulton and Watt, of Birmingham; and strongly recommending them to him, he observed that he was convinced if engines could be made capable of being transported to the mines of Pasco across the mountains they would be able to do it. Mr. Uville accordingly applied to these gentlemen, and fully explained to them the nature of the engines which would be wanted, and the state of the road by which they must be conveyed, and Messrs. Boulton and Watt returned an answer that it would be impossible to make engines small enough to be carried across the Cordillera to the mines.
