Pike's Expedition. The expedition from St. Louis through what is now Missouri, Kansas 

 and Colorado, to New Mexico, in charge of Lieutenant Zebulon Montgomery Pike, 

 1806, was the second expedition to the newly acquired Louisiana Territory. It was 

 undertaken by the order of General James Wilkinson, Commander of the Army, the 

 primary object being the safe delivery of the Osage Indians, then in St. Louis, to the 

 town of the Grand Osage. A second object was the accomplishment of peace between 

 various Indian tribes. A notebook was kept containing remarks upon the geographi- 

 cal structure, the natural history and population of the country through which the 

 expedition passed. Some mineral and botanical specimens were collected and meteor- 

 ological observations recorded. Pike's account of the expedition was published soon 

 after his return to the eastern states. This has not been seen by the compiler of this 

 bibliography.
