----------------------------Original message---------------------------- 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). - Paul Leverenz Scripps Inst. Oceanography Library
