104 LIFE OF BENJAMIN SILLIMAN. 



the reading of the interesting analyses of " the waters of 

 Montmorency and St. Charles Rivers," and the two papers 

 of Mr. Dana upon the growth and the trends of the islands

 ulation upon the native races which rapidly become extinct.* 

 However imposing the spectacle may be which is taking 

 place under our eyes, and which is preparing another far 

 more curious for the history of the intellectual development 

 of our species, I foresee the remote epoch when the high 

 degree of civilization and of institutions, free, stable, and 

 quiet (three elements which do not readily coalesce), will 

 penetrate into the tropical regions ; when, upon the high 

 plateaux, Mexico, Bogota, Quito, La Pax, Potosi, will re- 

 semble New York, Boston, Philadelphia. 



Accept, I beg you, Sir, yourself and your excellent 

 son, the renewed expression of my high and affectionate 

 consideration.
