          Kenton Spading:
 
          You neglected to cite the chart number but from my British
          Admiralty chart catalog it looks to be 2915 @ 1:176,000.
          As of their 1996 catalogue edition, the date of publication
          is 1864 with  new edition in March 1914 (as you indicated).
          There may be newer copies of this chart with CORRECTIONS,
          but unless you subscribe to B.A. notices to mariners you
          will have to ask the Admiralty what the date of the latest
          correction is.
 
          Probably however, the British Admiralty is no longer really
          interested in maintaining this chart due to proprietary
          issues with the Canadian Hydrographic Service who have their
          own charts of this area (4016,4613,4622). The United States
          Defense Mapping Agency has charts too which are to a major
          extent copies of the CHS charts (14349,14350,14360).  As per
          ususal, I am giving you more information than you probably
          care to know.
 
          For a concise background of the British Admiralty I
          recommend the introduction by Admiral G.S. Ritchie in THE
          SEA CHART by Derek Howse (ISBN 071535857X).
