Except as authorized by the preceding section, no merchandise brought in any vessel from any foreign port shall be unladen or delivered from such vessel within the United States but in open day—that is to say, between the rising and the setting of the sun—except by special license from the collector of the port, and naval officer of the same, where there is one, for that purpose, nor at any time without a permit from the collector, and naval officer, if any, for such unlading or delivery. (R. S., 2872.) When the license to unload between the setting and rising of the sun is granted to a sailing vessel under this section, a fixed, uniform, and reasonable compensation may be allowed to the inspector or inspectors for service between the setting and rising of the sun, under such regulations as the Secretary of the Treasury may prescribe, to be received by the collector from the master, owner, or consignee of the vessel, and to be paid by him to the inspector or inspectors. (June 26, 1884; sec. 25.) If any merchandise shall be unladen or delivered from any vessel contrary to the preceding section, the master of such vessel, and every other person who shall knowingly be concerned, or aiding therein, or in removing, storing, or otherwise securing such merchandise, shall each be liable to a penalty of four hundred dollars for each offense, and shall be disabled from holding any office of trust or profit under the United States, for a term not exceeding seven years; and the collector of the district shall advertise the name of such person in a newspaper printed in the State in which he resides, within twenty days after each respective conviction. (R. S., 2873.) All merchandise, so unladen or delivered contrary to the provisions of section twenty-eight hundred and seventy-two, shall become forfeited, and may be seized by any of the officers of the customs; and where the value thereof, according to the highest market price of the same, at the port or district where landed, shall amount to four hundred dollars, the vessel, tackle, apparel, and furniture shall be subject to like forfeiture and seizure. (R. S., 2874.) Supervision of unlading. The collector of any district at which any vessel arrives, immediately on her first coming within such district, or the surveyor of any port where such vessel is, may put and keep on board such vessel, while remaining within such district, or in going from one district to another, one or more inspectors to examine the cargo or contents of such vessel, and to superintend the delivery thereof, or of so much thereof as shall be delivered within the United States, and to perform such other duties according to law, as they shall be directed by the collector, or surveyor, to perform for the better securing the collection of the duties. Only collectors shall have power, however, to put inspectors on board vessels to go from one district to another. (R. S., 2875.)
