peaks, and the geographical position of those which have well-defined 
peaks. 
I need not inform you that sketches from the tops of high hills, with 
good bearings, will go far to illustrate the country through which you 
pass; the delay of a day for this purpose will be amply repaid by the 
information obtained. 
10th. It may be desirable for the scientific gentlemen to make occa¬ 
sional short excursions from your direct route. You will in that case 
afford all facilities in your power to prosecute their researches. 
11th. The information also expected from your party, will be names 
of tribes, numbers, manners, customs, mode of living, habits, charac¬ 
ter, disposition, and incidents that may occur to the party, as also the 
timber, kinds and quality, soils, climate, &c. And if you meet with 
any settlers, note their condition, whence from, &c. 
12th. Should you visit any of the forts or stations of the Honourable 
Hudson Bay Company, you will procure every information relative 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. 
13th. Keep your party always armed, night and day; this must 
never be omitted; a dog or two in your camp, besides the usual watch, 
would be advisable. 
All the gentlemen of your party will take turns in watching, and the 
others also divided according to their numbers. 
14th. You will study the safety as well as comfort of your party, 
and will 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,
