12th. Should you visit any of the forts or stations of the Honoura- 

 ble Hudson Bay Company, you will procure every information rela- 

 tive to them, together with that of any missionaries, and Indian 

 superstitions, tales of adventures, and history, that may be well 

 authenticated. The notes and journals should be full, and so as to be 

 well understood by others without the necessity of explanation ; also 

 a regular system of writing them up before going to rest.

 the others also divided according to their numbers. 



14th. You will study the safety as well as comfort of your party, 

 and wall bear in mind particularly the instructions for the intercourse 

 with natives in my General Order of the 1st of May last. 



The route to be pursued by the party, is up the Willamette Valley 

 in a southerly direction, crossing the Umpqua river and mountains, 

 thence south and west of the Shaste Mountains to latitude 42° N. 

 Very respectfully, your obedient servant,
