A steam-vessel shall be provided with an eflicient whistle or siren, sounded by steam or by some substitute for steam, so placed that the sound may not be intercepted by any obstruction, and with an eflicient fog-horn, to be sounded by mechanical means, and also with an efficient bell. [In all cases where the rules require a bell to be used a drum may be substituted on board Turkish vessels, or a gong where such articles are used on board small sea-going vessels.] A sailing vessel of twenty tous gross tonnage or upward shall be provided with a similar tbg-horn and bell. 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 two minutes, a prolonged blast. (b) A steam-vessel under way, but stopped, and having 110 way upon her, shall sound, at intervals of not more than two minutes, two prolonged blasts, with an interval of about one second between them. _ (c) A sailing vessel under way shall sound, at intervals of not more than one minute, when on the starboard tack one blast, when on the port tack two blasts in succession, and. when with the wind abaft the beam three blasts in succession (d) A vessel when at anchor shall, at intervals of not more than one minute, ring the bell rapidly for about five seconds. (e) A vessel at anchor at sea, when not in ordinary anchorage ground, and when in such a position as to be an obstruction to vessels under way, shall sound, if a steam-vessel, at intervals of not more than two minutes, two prolonged blasts with her whistle or siren, followed by ringing her bell; or, if a sailiugwessel, at intervals of not more than one minute, two b ts with her tbg-horn, followed by ringing her bell. (f) A vessel when towing shall, instead of the signals prescribed in subdivisions (a) and (c) of this article at intervals of not more than two minutes, sound three blasts in succession, namely, one prolonged blast ibllowed by two short blasts. A vessel towed may give this signal and she shall not give any other. (g) A steam-vessel wishing to indicate to another "Tl1e way is off my vessel, you may ieel your way past ine,” may sound three blasts in succession, namely, short, long, short, with intervals of about one second between them. (h) A vessel employed in laying or picking up as telegraph cable shall, on hearing the fog-signal of an approaching vessel, sound in answer three prolonged blasts in succession. (i) 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 maneuver as required by these rules, shall, on hearing the fog-signal of an approaching vessel, sound in answer four short blasts in succession. Sailing vessels and boats of less than twenty tons gross tonnage shall not be obliged to give the above-mentioned signals, but, if they do nut, they shall make some other efficient s0uud—signa1 at intervals of not more that one minute.

'When two sailing vessels are approaching one another, so as to involve risk of collision, one of them shall keep out of the way of the other, as follows, mamelv: (a) ik vessel which is running free shall keep out of the way of a vessel which is close-hauled.
