ENGLAND, EAST COAST.—RIVER THAMES ENTRANCE.

Closing of certain Channels and Special Regulations with Regard to Navigation.

For the purposes of national defence it is considered necessary that certain channels in the approaches to the Thames should be closed.

All incoming vessels flying foreign flags and all British vessels from all foreign and colonial ports must call at the new pilot-station now established in the vicinity of the Tongue Light-vessel, or at one of the established pilot-stations—viz., the Sunk Light-vessel, Margate, Deal, and Dover, and be conducted to their destination by a licensed pilot.

All outgoing vessels of the same description must before sailing obtain the services of a licensed pilot to conduct them to sea.

All incoming vessels not included in the above, before leaving their port of departure for the Thames, and all similar outgoing vessels, must obtain instructions from the nearest Customs authorities as to the channels to be used.

These arrangements are to take effect from noon, Monday, the 14th September.

NEWPORT ROCK.—DREDGING IN PROGRESS IN VICINITY.—REGULATIONS FOR SHIPS PASSING DREDGER.—Position: Newport Rock, lat. 29° 53′ N., long. 32° 33′ E. Details: Dredging is in progress in the channel to the westward of Newport Rock, and the following dredger regulations are to be observed for ships passing the dredger:—

By Day.—While the dredger is working in the channel a red flag will be hoisted at the masthead, and no ship is to attempt to pass her until she has hauled to one side and indicated that the passage is clear by hauling down the red flag and hoisting the Canal Company’s flag on an inclined mast from the bridge. Ships must pass the dredger on the side on which this flag is hoisted.

By Night.—The dredger will indicate when she has hauled to one side and the passage is clear by hoisting two lights at the height of the netting on the side on which ships must pass her, and one light at the masthead.

Note: When the dredger is at work on the patch, situated at a distance of about 7 cables, southward, from Newport Rock, the light-buoy marking this patch will be removed, the dredger taking its place, and while in this position ships must pass to the eastward of her.

LOCATION OF MINES.—The Admiralty state in the event of locating mines, it is essential that the most careful determination should in every case be made of the position of the mine by as many cross bearings as possible, if in sight of land; if out of sight of land the position should be determined by observation or dead reckoning, and in such cases a cast of the lead should also be obtained if possible. In all cases, whenever practicable, a mark-buoy of large and distinctive size with efficient moorings should be dropped as close to the mine as possible. These measures are essential so as to enable H.M. vessels to locate and destroy them. Sept.
