284 APPENDIX. 



over a rocky bed, whicli forms a continuous succession of rapids, 

 all of whicli are difficult and some dangerous. The country, too, 

 begins here to open, and the immense plains in which the buffa- 

 loes range approach the river. These plains continue to the 

 Falls of St. Anthony. 



They are elevated fifty or sixty feet above the Mississippi, are 

 destitute of timber, and present to the eye a flat, uniform surface, 

 bounded at the distance of eight or ten miles by high ground. 

 The title of this land is in dispute between the Chippewas and 

 Sioux, and their long hostilities have prevented either party from 

 destroying the game in a manner as improvident as is customary 

 among the Indians. It is consequently more abundant than in 

 any other region through which we travelled. 



From the post, at the mouth of the St. Peter's, to Prairie du 

 Chien, and from that place to Green Bay, the route is too well- 

 known to render it necessary that I should trouble you with any 

 observations respecting it. 



The whole distance travelled by the party between the 24th of 

 May and the 24th of September exceeded 4,200 miles, and the 

 journey was performed without the occurrence of a single unto- 

 ward accident sufficiently important to deserve recollection. 



These notices are so short and imperfect that I am unwilling to 

 obtrude them upon your patience. But the demands upon your 

 attention are so imperious, that to swell them into a geographical 

 memoir would require more time for their examination than any 

 interest which I am capable of giving the subject would justify. 



I propose hereafter to submit some other observations to you 

 in a different shape. 



Very respectfully, sir, 



I have the honor to be 



Your obedient servant, 



LEWIS CASS. 



Hon. J. C. Calhoun, Secretary of War.
