Vessels of Prussia.- No other or higher rate of duties shall be imposed or collected on vessels of Prussia, or of her dominions, from whencesoever coming, nor on their cargoes, howsoever composed, than are or may be payable on vessels of the United States, and their cargoes. § 4230. Termination of privileges.-The preceding section shall continue and be in force during the time that the equality for which it provides shall, in all respects, be reciprocated in the ports of Prussia and her dominions; and if at any time hereafter the equality shall not be reciprocated in the ports of Prussia and her dominions, the President may issue his proclamation, de claring that fact, and thereupon the section preceding shall cease to be in force. § 4231.

Rules for preventing collisions.-The following rules for preventing collisions on the water, shall be followed in the navigation of vessels of the Navy and of the mercantile marine of the United States: STEAM AND SAIL VESSELS. Rule one. Every steam-vessel which is under sail, and not under steam, shall be considered a sail-vessel; and every steam-vessel which is under steam, whether under sail or not, shall be considered a steam-vessel. LIGHTS. Rule two. The lights mentioned in the following rules, and no others, shall be carried in all weathers, between sunset and sunrise. Rule three. All ocean-going steamers, and steamers carrying sail, shall, when under way, carry (A) At the foremast head, a bright white light, of such a character as to be visible on a dark night, with a clear atmosphere, at a distance of at least five miles, and so constructed as to show a uniform and unbroken light over an arc of the horizon of twenty points of the com pass, and so fixed as to throw the light ten points on each side of the vessel, namely, from right ahead to two points abaft the beam on either side. (B) On the starboard side, a green light, of such a character as to be visible on a dark night, with a clear atmosphere, at a distance of at least two miles, and so constructed as to show a uniform and unbroken light over an arc of the horizon of ten points of the compass, and so fixed as to throw the light from right ahead to two points abaft the beam on the starboard side. (C) On the port side, a red light, of such a character as to be visible on a dark night, with a clear atmosphere, at a distance of at least two miles, and so constructed as to show a uniform and unbroken light over an arc of the horizon of ten points of the compass, and so fixed as to throw the light from right ahead to two points abaft the beam on the port side. The green and red lights shall be fitted with inboard screens, projecting at least three feet forward from the lights, so as to prevent them from being seen across the bow. Rule four. Steam-vessels, when towing other vessels, shall carry two bright white mast-head lights vertically, in addition to their side-lights, so as to distinguish them from other steam-vessels. Each of these mast-head lights shall be of the same character and construction as the mast-head lights prescribed by Rule three. Rule five. All steam-vessels, other than ocean-going steamers and steamers carrying sail, shall, when under way, carry on the starboard and port sides lights of the same character and construction and in the same position as are prescribed for side-lights by Rule three, except in the case provided in Rule six. Rule six. River-steamers navigating waters flowing into the Gulf of Mexico, and their tributaries, shall carry the following lights, namely: One red light on the outboard side of the port smoke-pipe, and one green light on the outboard side of the starboard smoke-pipe. Such lights shall show both forward and abeam on their respective sides. Rule seven. All coasting steam-vessels, and steamvessels other than ferry-boats and vessels otherwise expressly provided for, navigating the bays, lakes, rivers, or other inland waters of the United States, except those mentioned in Rule six, shall carry the red and green lights, as prescribed for ocean-going steamers; and, in addition thereto, a central range of two white lights; the after-light being carried at an elevation of at least fifteen feet above the light at the head of the vessel. The headlight shall be so constructed as to show a good light through twenty points of the compass, namely: from right ahead to two points abaft the beam on either side of the vessel; and the after-light so as to show all around the horizon. The lights for ferry-boats shall be regulated by such rules as the board of supervising inspectors of steam-vessels shall prescribe. Rule eight. Sail-vessels, under way or being towed, shall carry the same lights as steam-vessels under way, with the exception of the white mast-head lights, which they shall never carry. Rule nine. Whenever, as in case of small vessels during bad weather, the green and red lights cannot be fixed, these lights shall be kept on deck, on their respective sides of the vessel, ready for instant exhibition, and shall, on the approach of or to other vessels, be exhibited on their respective sides in sufficient time to prevent collision, in such manner as to make them most visible, and so that the green light shall not be seen on the port side, nor the red light on the starboard side. To make the use of these portable lights more certain and easy, they shall each be painted outside with the color of the light they respectively contain, and shall be provided with suitable screens. Rule ten. All vessels, whether steam-vessels or sailvessels, when at anchor in roadsteads or fairways, shall, between sunset and sunrise, exhibit where it can best be seen, but at a height not exceeding twenty feet above the hull, a white light in a globular lantern of eight inches in diameter, and so constructed as to show a clear, uniform, and unbroken light, visible all around the horizon, and at a distance of at least one mile. Rule eleven. Sailing pilot-vessels shall not carry the lights required for other sailing-vessels, but shall carry a white light at the mast-head, visible all around the horizon, and shall also exhibit a flare-up light every fifteen minutes. Rule twelve. Coal-boats, trading-boats, produce-boats, canal-boats, oyster-boats, fishing-boats, rafts, or other water-craft, navigating any bay, harbor, or river, by handpower, horse-power, sail, or by the current of the river, or which shall be anchored or moored in or near the channel or fairway of any bay, harbor, or river, shall carry one or more good white lights, which shall be placed in such manner as shall be prescribed by the board of supervising inspectors of steam-vessels. Rule thirteen. Open boats shall not be required to carry the side-lights required for other vessels, but shall, if they |
