In December 1958 the Institute held a meeting at the Royal Geographical Society at the suggestion of the Hydrographer of the Navy, to sound sea-going opinion on the Admiralty Chart. An account of the meeting was given in Volume 12 of the Journal. The discussion printed below took place at a meeting of the Institute held on 17 February, again at the suggestion of the Hydrographer of the Navy, to take account of what steps had been taken as a result of the last meeting and to examine the situation further. The discussion was introduced by Rear-Admiral E. G. Irving, O.B.E., the Hydrographer of the Navy who had with him the heads of the various branches within the Hydrographic Department.

The Hydrographer referred to the many points which had been made by Masters at the last meeting and in correspondence resulting from it and an account of what has been done as a result of these suggestions is given as an appendix to this discussion.

The Hydrographer: Of the general topics raised at the last meeting I would like to mention a few because I wish to stimulate discussion on these points in order to obtain guidance for future policy.
