These Marines were sent from China to 
B. Columbia shortly after the
                     establishment of that place as a Colony, when the naval force
                     stationed there was inadequate for its protection and, I think,
                     before the Royal Engineers had [one word off file] the Colony.
                     I do not believe that
                     after all they were employed on shore, or at any rate that their land
                     Service was of any duration, and that ultimately they were
                     distributed amongst the Squadron. Since that period the 
San Juan
                     difference arose, and the The 
Foreign Office, on the part of H.M.
                     
Gov, ordered the 
Admiralty to station 100 Marines on the Island,
                     the United States placing a corresponding Military force there. Of
                     this Order of 
Lord J. Russell's the 
Admiralty are necessarily
                     cognizant. Whether or not the Admiral could have detached 100
                     Marines to 
San Juan if he had not had in hand the supernumerary
                     Marines from China I am unable to say as we are not acquainted at
                     this office with the strength of the Marines in the Squadron in the
                     N. Pacific. I only know that when, about this time last year, it was
                     proposed to diminish the Marines the 
Duke of Newcastle considered
                     the moment for doing so unopportune, and that the force has since
                     then been kept up at 

the full strength plus the men from China. It
                     now appears that the period of service for these Marines has expired
                     and that in ordinary course they must be relieved. The question
                     thence arises whether if they are sent home the Admiral on the Station
                     has Marines enough left to perform their duties on board of Ship,
                     and the service at 
San Juan also. On this point the Adm should, I
                     think, be requested to afford some information. If the answer be
                     that the force is strong enough to fulfil both services I presume
                     that the Supernumeraries may be recalled, but if it be insufficient I
                     conceive that other Marines must be sent out to replace those who are
                     withdrawn. I am assuming that the 
San Juan difficulty has not made
                     that progress towards solution which 

would enable the two Governments
                     to withdraw their respective military detachments. It is on this
                     point that some communication with the 
Foreign Office may be requisite.
