Dear Sir,— 
Being obliged from the lateness of the season to abandon the inten¬ 
tion I had of using the launch of the late United States ship Peacock 
for the exploration of the coast to the southward of this river, I have 
thought that I could not possibly place her to a better use than by 
leaving her as a pilot-boat for communication with vessels off the 
dangerous bar of this river, and to afford relief, by giving pilots and 
assistance to those that are coming in, or in cases of accident. 
It was my intention to have spoken to you on the subject before I 
left Vancouver; but, among the many duties that occupied my atten¬

I have spoken to Mr. Burnie in relation to taking the launch in 
charge for that purpose, but he has referred me to you, as he did not 
feel authorized to assume the responsibility of acting for the Company. 
I will now state in a few words the charge I wish the Honourable 
Hudson Bay Company to assume, viz.: 
That the launch be kept at Fort George, under the special charge 
of the agent of the Hudson Bay Company, for the sole purpose of 
affording aid and relief to all vessels requiring assistance of any kind, 
and to furnish pilots for entering the river, until called for by some
