APPENDIX.

Mr. Rodgers will also accompany you, as interpreter, caterer, &c.; 
he having been engaged by me for that purpose, for the explanation 
of the district pointed out to you on the accompanying map. 
Your arrangements will be completed as early as possible, and you 
will be careful that the organization of your party is complete, and 
that they maintain a due obedience to your orders and authority during 
this service, for on it will depend their safety. 
I cannot too strongly impress upon you the necessity of constant 
watchfulness and caution, in the steps you will pursue, and of acquir¬ 
ing the information necessary to enable you to judge for yourself. 
It is desirable to avoid all collision with the Indians, if possible, 
without, however, showing them that you do so; and if unavoidably 
attacked, you must not only repulse them, but punish them, as far as 
•nay lay in your power, exercising due discretion. 
The men whom Mr. Rodgers is to engage at the Willamette settle¬ 
ment, will require of you particular attention. You will know their 
terms of engagement: for the performance of which, and their good 
behaviour, their pay will be made answerable. 
You will observe strictly the following instructions: 
1st. The route I have pointed out to you is believed to be feasible, 
but as the country is unknown, it may not be so. You are not at 
liberty to depart from it, however, without good and sufficient reasons. 
You will, however, particularly note: my object is to get all the 
information respecting the district I have marked in red, and you will 
endeavour to get this as accurate as possible, by travelling over as 
much of its surface as your time will admit of. 
2d. Your absence is limited to the 10th of September, and I am 
convinced that much knowledge may be gained of the district pointed 
out to your party in that time. 
3d. Observations for latitude and longitude wherever you may 
encamp. 
4th. You will keep an accurate map of your route, noting on it all 
lakes, rivers, plains, mountains, and every thing worthy of notice, to 
illustrate its features. For this purpose, furnish yourself with a blank- 
book of foolscap size, and use each leaf for a day’s work ; the ruled 
places will answer the purpose of a scale, and be sufficiently large to 
insert every thing desirable to note. 
5th. You will be furnished with a pocket chronometer, sextant, 
artificial horizon, prismatic compass, barometer, thermometers, Nau¬ 
tical Almanac, and Book of Tables, which will enable you to obtain 
all kinds of observations; and I shall expect you to be very particular
