territory comprehended between the Mississipi and the Pacific 

 Ocean, does not contain 741,414 square miles (namely, the 

 state of Louisiana, deducting what is eastward of the Mis- 

 sissipi, 48,200 — 9,215 = 39,005 j territory of Arkansas,

 the West, 180,114 (Warden, Vol. i, p. 101 5 Vol. iv, p. 

 563, 653) ; but 1,156,800 square miles. A well-informed 

 geographer, whom Mr. Warden had employed in those calcu- 

 lations of surface, repeated them at my desire 5 and, in em- 

 ploying the real logarithms of reduction, found the territory 

 of Missouri, comprehending the state of that name, nearly 

 as I did, to be 696,000 square miles, instead of 445,334 j 

 the territory of the West, 284,000 square miles, instead of 

 180,114 ; and the territory of Arkansas, 125,855 square 

 miles, instead of 76,961. These partial errors, which bear 

 only on the most unpeopled part of the American territory, 

 and from which the calculations of surface in the English 

 edition of Mr. Warden's work are entirely exempt, produce a 

 total difference of more than 400,000 square miles, or 

 33,400 square marine leagues. M. Adrien Balbi, who in his 

 statistical essay on the kingdom of Portugal has collected a 

 great numbes of precious materials for the study of political 

 economy in general, computes the area of the United States 

 (Vol. i, p. 259,) to be 2,146,000 Italian square miles, 60 to 

 a degree (238,000 square marine leagues). This estimate is 

 nearly one-fifth too great. On the other hand, the results fixed 

 on by Mr. Morse, in a very instructive work just published 

 at Boston, with the title System of Modern Geography, differ 

 very little from mine for the eastern part of the confederation. 

 He fixes the United States at 377,446 square miles ; now, 

 deducting 90,200 for the portion of those states lying west 

 of the Alleghanies, and adding 52,300 for Florida, on the 

 east of Apalachicola, we obtain, for the division a, 339,600 

 square miles. The eight states and territories situated be* 

 tween the Atlantic States and the Mississipi, comprehending
