PREFACE. 



IN treating of the Climate, the Geology, and 

 the Winds of the United States, the divisions and! 

 remarks of Mr. Volney have been assumed as the 

 basis : — in many respects they are extremely ac- 

 curate and ingenious, and justify the opinion which 

 has been formed of his talents for physical geogra- 

 phy ; but care has been taken, at the same time, 

 to correct some important errors, into which he 

 had fallen, and to supply his defects. As to the 

 rest of the work, the authorities upon which the 

 facts and statements are founded, are generally giv- 

 en, and the reader may be assured, that the most 

 scruptilous attention has beei> exercised in ascer- 

 taining their accuracy.
