APPENDIX. 535 



After having fixed your encampment, you will erect a tide-staff, and 

 keep the hourly observations, as also the noting of the times of equal 

 altitudes on the staff between tides. 



The set of the currents, in and out of the harbour, at different times 

 of the tide, will be attended to; and a rough diagram of their flow, by 

 the direction of arrows, will prove satisfactory to make your observa- 

 tions intelligible. 



If you find a projecting cape at the mouth of the harbour, you will 

 not fail to get several azimuthal observations on the different points 

 north and south, establishing the correct trending of the coast. The 

 latitude and longitude of this point you will carefully determine. 



After having finished this survey, you will proceed along the coast 

 in your canoes (choosing a smooth time), and sketch its trendings and 

 outlines to Shoalwater Bay, from whence you will despatch a letter 

 for me, directed to Mr. Birnie, at Fort George, and proceed to survey 

 with all accuracy that bay, until you have finished it, and the shores 

 around to Cape Disappointment, which had better be done on shore, as 

 the rollers near the cape are to be cautiously guarded against in the 

 canoes you are to effect your work in. 



From Shoalwater Bay you will pass over a small portage, when 

 you will enter a lake that -has its outlet in Baker's Bay, where you 

 will join the ships, or await my arrival there. 



In executing this duty, you will be very particular as respects the 

 safety of your party from the natives, taking great care to avoid any 

 collision with them, and to take up your encampments at remote dis- 

 tances from their lodges. Your party are provided with the neces- 

 sary arms to protect themselves. None of them must be disposed of, 

 nor any thing else given for trade, and you will take particular care 

 and use great economy in the expenditure of every thing belonging to 

 the government, and not abandon any thing, except through absolute 

 necessity, in which decision the officer who accompanies you must 

 coincide. 



Before quitting Gray's Harbour, you will see that all the work of 

 the survey is plotted, and a copy of it taken on tracing paper, which 

 must be deposited in a separate place, to prevent the loss of both. 



I am aware that you may be detained a few days on account of the 

 surf and weather; but do not risk your men, or omit to perform the 

 duly assigned you. 



These orders you will show to Passed Midshipman Eld, that he 

 may take a note of them, in case of accident. 



A full report will be expected from you, relative to the country
