424 Expedition to the 



the expedition by order of the War Department, with the 

 exception of those parts which relate to the manners, cus- 

 toms, and traditions of the various savage tribes which we 

 may pass. The duties thus excepted will be performed by 

 Mr. Say. The duties assigned to Dr. Baldwin and Mr. 

 Jessup, by the order alluded to, will be performed by Dr. 

 E. James, employed for these purposes by the sanction of 

 the Secretary of War. In these duties are excepted those 

 parts which relate to Comparative Anatomy, and the diseas- 

 es, remedies, &c. known amongst the Indians ; which will 

 also be performed by Mr. Say. 



Lieutenant Graham will take charge of the United States' 

 steam boat Western Engineer, and proceed down the Mis- 

 souri to the Mississippi with the remaining part of the crew 

 originally attached to the boat, on the performance of duties 

 assigned him by special order. 



The detatchment from the rifle regiment, attached to the 

 Expedition by order from the commanding officer of the 9th 

 military department, will accompany the expedition in their 

 route from this place to Belle Point on the Arkansa, under 

 the immediate command of Lieutenant Swiit, who will in- 

 spect daily their arms and accoutrements, and report their 

 condition to the commanding officer. He will receive such 

 instructions from the commanding officer as occasion may 

 require in relation to the discharge of his duties. 



Guides, interpreters, hunters, and others attached to the 

 expedition, will perform such duties as may be assigned, 

 from time to time, by the commanding officer. 



The duties of the expedition being arduous, and the ob- 

 jects in view difficult of attainment, the hardships and ex- 

 posures to be encountered, requiring zealous and obstinate per- 

 severance, it is confidently expected, that all embarked in the 

 enterprize will contribute every aid in their power, tending to 

 a successful and speedy termination of the contemplated tour. 



S. H. Long, Maj. Engrs. 

 Commanding Exploring Expedition.
