 TREATIES In fog, mist, falling snow or heavy rain-storms, whether by day or night, the signals described in this Article shall be used as follows, viz.:- (a.) A steam vessel having way upon her, shall sound, at intervals of not more than 2 minutes, a prolonged blast. (b.) A steam vessel under way, but stopped and having no way upon her, shall sound, at intervals of not more than 2 minutes, 2 prolonged blasts, with an interval of about 1 second between them. (c.) A sailing vessel under way shall sound, at intervals of not more than 1 minute, when on the starboard tack, 1 blast, when on the port tack, 2 blasts in succession, and when with the wind abaft the beam, 3 blasts in succession. (d.) A vessel, when at anchor, shall, at intervals of not more than 1 minute, ring the bell rapidly for about 5 seconds. In vessels of more than S50 feet in length the bell shall be sounded in the forepart of the vessel, and, in addition, there shall be sounded in the after-part of the vessel, at intervals of not more than 1 minute, a gong or other instrument, the tone of which cannot be confused with the ringing of the bell. (e.) A vessel, when towing, a vessel employed in laying or in picking up a telegraph submarine cable, and a vessel under way, which is unable to get out of the way of an approaching vessel through being not under command, or unable to manceuvre as required by these Rules shall, instead of the signals prescribed in subdivisions (a), (b) and (c) of this Article, at intervals of not more than 2 minutes, sound 3 blasts in succession, viz., 1 prolonged blast followed by 2 short blasts. A vse4s. towed iay give th4s signal ftid she shOl noet give any ether. A vessel towed, or if more than one vessel is towed, the last vessel of the tow, shall, at intervals of not more than 2 minutes, sound 4 blasts in succession, viz., 1 prolonged blast followed by 3 short blasts, provided that this signal is not required when it is impossible to keep the vessel manned. When practicable, the vessel towed shall make this signal immediately after the signal made by the towing vessel. (f.) A vessel aground in or near a fairway shall give the signal pre- scribed in paragraph (d), and shall, in addition, give 3 separate and distinct strokes on the bell immediately preceding and following each such signal. Sailing vessels and boats of less than 20 tons gross tonnage shall not be obliged to give the above-mentioned signals, but, if they do not, they shall make some other efficient sound-signal at intervals of not more than 1 minute.t t Dutch steam pilot-vessels, when engaged on their station on pilotage duty in fog, mist, falling snow, or heavy rain-storms are required to make at intervals of 2 minutes at most one long blast with the siren, followed after 1 second by a long blast with the steam whistle and again after 1 second by a long blast on the siren. When not engaged on their station on pilotage duty, they make the same signals as other steamships. [Footnote in the original.] 1296
