 Spirit and they must submit. It was with difficulty the 

 Seminoles were induced to assent to the treaty of cession, 

 and they would probably resist its execution if they had 

 any chance of success. Several of the chiefs have reser- 

 vations, and are permitted to remain in West Florida, with 

 a limited number of followers. There are now several 

 Indian villages in the great southern reservation.

 at the time, but neglected to do so. Yesterday, however, 

 in reading a review of Dr. Dwight's travels, in the Quar-
