 lately, in his Report on the Geology of JVorth 

 Carolina^ executed it in a manner worthy of 

 his high reputation as a geologist. 



The honorable and praiseworthy direction 

 of the energies of the nation towards inter- 

 nal improvement, has elicited several excel- 

 lent geological essays. Of these, we would
