With reference to the question of the Northwestern Boundary and
               the possession of the 
Island of San Juan, I have the honor to
               enclose for Your Lordship's information a
tracing
               tracing of a portion
               of a Map published in 
1848 under the authority of the Senate of
               the United States, of which a copy has been found here in the
               Lands & Works Office. I believe this to be the one referred to
               by 
Captain Prevost in his correspondence with 
M Archibald
                  Campbell on the discussion of the
question
               question of Boundary in
               
November 1857. Probably Your Lordship's Department is already
               furnished with this Map, but it may be useful to know where
               another Copy can be found in case one should be wanted. It
               certainly appears to afford evidence that at the date if its
               compilation the group of Islands in the 
Gulf ofGeorgia Georgia
               Georgia
               Georgia was
               regarded by the authorities of the United States as belonging to
               
Vancouver Island.
