Notice to Mariners.—No. 7 of 1921.
Marine Department,
Wellington, N.Z., 8th February, 1921.

THE following Notices to Mariners, which have been received from the Board of Trade, London; the Department of Ports and Harbours, Melbourne; the Department of Trade and Customs, Melbourne; and the Harbours Board Offices, Adelaide, are published for general information.
ROBERT DUNCAN, Secretary.
WARNING SIGNS DISPLAYED BY VESSELS ACCOMPANYING SUBMARINES.
ATTENTION is specially drawn to the following information with regard to vessels accompanying submarines:
British men-of-war, auxiliary patrol vessels, Royal fleet and mercantile fleet auxiliaries, and all British merchant vessels and Italian Royal naval vessels, whenever proceeding in company with submarines will fly “M” (International) at the masthead, accompanied by a group from the numeral table in the International Code of Sigs. indic. the number of submarines in company. This sig. is a warning to vessels that submarines are in the vicinity. When “M” flag is displayed vessels are cautioned to steer so as to give the escorting vessel a berth of at least one mile, and also to pass astern of her. When from any cause this cannot be done. the escorting vessel should be approached at slow speed until warning is given of the danger zone by flags, semaphore, or megaphone, as most convenient, a good look-out being kept meanwhile for the submarines, whose presence may be only indic. by their periscopes showing above water. The use of the large red flag has been disc. for this purpose.
Further information has been received that the warning signs above referred to are not in use in the French Navy.
The regulations and sighs. relative to French submarines given in the Admiralty Sailing Directions, with exception of No. 6 Supplement to W. Coast of France, &c., Pilot, remain in force; the information under this heading in Supplement to Mediterranean Pilot, Vol. I, is cancelled.

METHOD OF EXPRESSING ASTRONOMICAL TIME IN NAUTICAL ALMANAC.—INTENDED CHANGE.
Attention is drawn to the following information with regard to the method of expressing G.M.T. in the Nautical Almanac and intended change therein. In both the abridged and complete Nautical Almanac the times styled G.M.T. are at present reckoned from noon, corresponding to 12 hours (civil time); but from the year 1925 inclusive and thenceforward the times styled G.M.T. in these publications will be given commencing at midnight, to conform with civil time; the term “Greenwich mean time” will then be considered to be the standard time of the meridian of Greenwich, commencing at midnight and reckoned throughout the twenty-four hours. Printed slips drawing attention to the above will shortly be available, and may be obtained from J. D. Potter (Agent for the Sale of Admiralty Charts) or his subagents. These slips are intended to be pasted in Nautical Almanacs already for sale, and the information on the slip will be printed in editions of the Nautical Almanac now preparing. Further notices will be issued illustrating or referring to the manner in which Nautical Almanacs of 1925 and onwards will differ from those relating to previous years.
