As amended by Act of February 27th, 1877, 19 U. S. Stats. 250. Decision of collector conclusive after ten days' acquiescence-Rev. Stats. sec. 2931. Vessels coming from ports in the British Colonies must pay full duties as on foreign vessels-U. S. v. Hathaway, 3 Mason, 324. The charge of "light money" is confined to the vessel, and binds the owner-U. S. v. Hathaway, 3 Mason, 324.

§ 4220. Exemption of coasting and fishing vessels.-No vessel belonging to any citizen of the United States, trading from one port within the United States to another port within the United States, or employed in the bank, whale, or other fisheries, shall be subject to tonnage tax or duty, if such vessel be licensed, registered or enrolled. [See § 2793.]

§ 4221. Exemption of vessels on interior waters. In cases of vessels making regular daily trips between any port of the United States and any port in the Dominion of Canada, wholly upon interior waters not navigable to the ocean, no tonnage or clearance fees shall be charged against such vessel by the officers of the United States, except upon the first clearing of such vessel in each year.

§ 4222. Exemption of Canadian ports.-No consul or consular agent of the United States shall exact tonnage fees from any vessel of the United States, touching at or near ports in Canada, on her regular voyage froin one port to another within the United States, unless such consul or consular agent shall perform some official services, required by law for such vessel, when she shall thus touch at a Canadian port.

Enrolled or licensed vessels engaged in the foreign and coasting trade on the frontiers of the United States, touching at intermediate ports, are required to enter and clear, but they do not become liable as vessels from or to foreign ports-Rev. Stats. sec. 2793.

§ 4223. Payment of tonnage duty.- The tonnage duty imposed on all vessels engaged in foreign commerce shall be levied but once within one year, and, when paid by such vessel, no further tonnage tax shall be collected within one year from the date of such payment. But this provision shall not extend to foreign vessels entered in the United States from any foreign port, to and with which vessels of the United States are not ordinarily permitted to enter and trade.

§ 4224. Time of payment.-Vessels which pay tonnage duties once in a year shall pay the same either at their first clearance from or entry at, according to priority, a custom-house in the United States in each calendar year. Nothing in this section shall be construed to prevent customs officers from collecting such tonnage duty at the entry of vessels at their respective custom-houses during the calendar year if the same has not previously been paid for such year.

§ 4225. Light-money.-A duty of fifty cents per ton, to be denominated "light-money," shall be levied and collected on all vessels not of the United States, which may enter the ports of the United States. Such lightmoney shall be levied and collected in the same manner and under the same regulations as the tonnage duties.

§ 4226. Exemption of unregistered vessels owned by citizens.- The preceding section shall not be deemed to operate upon unregistered vessels, owned by citizens of the United States, and carrying a sea-letter, or other regular document, issued from a custom-house of the United States, proving the vessel to be American property. Upon the entry of every such vessel from any foreign port, if the same shall be at the port at which the owner or any of the part owners reside, such owner or part owners shall make oath that the sea-letter or other regular document possessed by such vessel contains the name or names of all the persons who are then the owners of the vessel; or if any part of such vessel has been sold or transferred since the date of such sea-letter or document, that such is the case, and that no foreign subject or citizen has, to the best of his knowledge and belief, any share, by way of trust, confidence, or otherwise, in such vessel. If the owner or any part owner does not reside at the port or place at which such vessel shall enter, then the master shall make oath to the like effect. If the owner or part owner, where there is one, or the master, where there is no owner, shall refuse to so swear, such vessel shall not be entitled to the privileges granted by this section.

§ 4227. Rights under treaties.-Nothing contained in this Title shall be deemed in anywise to impair any rights and privileges which have been or may be acquired by any foreign nation under the laws and treaties of the United States relative to the duty on tonnage of vessels, or any other duty on vessels.
