In this case vessels must either proceed to the position marked "Examination Anchor- age" on the Admiralty Charts and anchor there, or keep the sea.

(3) At all the ports or localities at home or abroad referred to at the end of this Notice, search lights are occasionally exhibited for exercise, and this may make navigation difficult when approaching them.

Instructions have been given to avoid directing moveable lights towards vessels under way, but mariners are warned that great caution is necessary when search lights are being exercised.

II.

EXAMINATION SERVICE.

(1) Under certain circumstances it may become necessary to take special measures to examine vessels desiring to enter the ports or localities in the United Kingdom and His Majesty's Possessions abroad, mentioned at the end of this Notice.

(2) In such case, vessels carrying the distinguishing flags or lights mentioned in para- graph (4) will be charged with the duty of examining ships which desire to enter the ports and of allotting positions in which they shall anchor.

(3) As the institution of the Examination Service at any port will never be publicly advertised, especial care should be taken in approaching the ports, by day or night, to keep- a sharp look-out for any vessel carrying the above-mentioned flags or lights, and to be ready to "bring to at once when hailed by her or warned by the firing of a gun.

(4) By day the distinguishing flags of the Examination Steamer will be a special flag (white and red horizontal surrounded by a blue border) and a blue ensign.

Also, three red vertical balls if the port is closed.

By night the steamer will carry :—

(a) Three red vertical lights if the port is closed. (b) Three white vertical lights if the port is open.

The above lights will be carried in addition to the ordinary navigation lights, and will show an unbroken light around the horizon.

(5) Masters are warned that, before attempting to enter any of these ports when the Examination Service is in force, they must in their own interests strictly obey all instruc- tions as to entry given to them by the Examination Steamer. In the absence of any in- structions from the Examination Steamer they must proceed to the position marked Ex- amination Anchorage" on the Admiralty Charts and anchor there.

(6) In case of fog Masters of vessels are enjoined to use the utmost care, and the Examination Anchorage itself should be approached with caution.

(7) The pilots attached to the ports will be acquainted with the regulations to be followed.
