IV PREFACE. 



now freed from the pressure in other quarters, can di- 

 rect their whole force against them. 



" In addition to the other considerations you may 

 urge, I enclose a speech to be delivered to them, which 

 you will please to accompany with a proper belt. I 

 think it will be best for them to send a message to the 

 Sioux without delay, stating their determination to re- 

 frain from hostilities in conformity with the wish of their 

 great father the President, and their adhesion to the 

 treaty of Prairie du Chien. This message should be 

 sent while you are with them, and I recommend that 

 one from you be likewise sent to the Sioux, explana- 

 tory of the matter. 



" You will proceed to the execution of this duty 

 without delay, if the season be not too far advanced 

 when you receive this letter. But I am apprehensive 

 it will not reach you in season. Should it be so, you 

 will please send a message to the chiefs stating your 

 intention to visit them next summer, and recommend- 

 ing them to sit still until you can see them. It may 

 have the effect of keeping them quiet. If, however, 

 you cannot proceed this fall, it is probable that circum- 

 stances may require some change in these instructions 

 before the next season, and your arrangements must 

 therefore depend upon such as may be hereafter given.'' 

 4i Very respectfullv, &c.

 Sir : Since writing the letter to you of the 5th in- 

 stant, Gov. Cass has arrived here, and submitted to the 

 Secretary of War his views, as to the propriety of di- 

 recting you to proceed into Lake Superior and the 

 Mississippi country, &c. These views have been ap- 

 proved, and I am accordingly directed to instruct you

 jects to be accomplished are so well known, and have 

 also been so fully explained in the letter of Gov. Cass
