166 Expedition, &c. 



" It is believed that the field for observation and inquiry is 

 here so extensive, that all the gentlemen of the expedition 

 will find ample range for the exercise of their talents, in their 

 respective pursuits, and it is hoped that through their unre- 

 mitted exertions and perseverance, a rich harvest of useful 

 intelligence will be acquired." 



On the 1 1th of October, Major Long and Mr. Jessup took 

 Jeave of their friends at Engineer Cantonment, and accom- 

 panied by several other persons, began to descend the Mis- 

 souri in a canoe, on their way towards Washington and Phi- 

 ladelphia.
