EXTINGUISHED VOLCANO. 



gentleman, except that I had heard he was well 

 when I left Europe. It is but justice to say 

 that, wherever I have followed the steps of 

 the Baron Humboldt, I have heard the most 

 friendly and anxious enquiries after him, and 

 all unite in pronouncing an eulogy on his 

 urbanity of manner, endearing conduct, and 

 gentlemanly deportment. 



Jan. 13th. In a conversation with M. Le 

 Roche, he informed me that he had travelled 

 over Buenos-Ayres and the mountains of 

 Peru. He said that in the plains of Buenos- 

 Ayres, about one hundred and fifty leagues 

 from that city, is to be seen the Sierra de 

 Moro, an extinguished volcano, near to the 

 Sierra de San Luis. He examined it as far 

 as he could descend, which was a consider- 

 able distance, and from thence a large stone 

 thrown down did not return any sound. May 

 it not be worth the while of some future travel- 

 ler, provided with Sir Humphrey Davy's lamp, 

 and having erected a windlass, or crane, on 

 the top, to descend this crater, examine more 

 closely the strata of the earth, and scrutinize 

 more intimately the geological formation of 

 the interior of this globe ?
