The master of every vessel bound on a foreign voyage or engaged in the whale fishery shall exhibit the certified copy of the list of the crew to the first boarding officer at the first port in the United States at which he shall arrive on his return, and also produce the persons named therein to the boarding officer, whose duty it shall be to examine the men with such list and to report the same to the collector; and it shall be the duty of the collector at the port of arrival, where the same is different from the port from which the vessel originally sailed, to transmit a copy of the list so reported to him to the collector of the port from which such vessel originally sailed. For each failure to produce any person on the certified copy of the list of the crew the master and owner shall be severally liable to a penalty of four hundred dollars, to be sued for, prosecuted, and disposed of in such manner as penalties and forfeitures which may be incurred for offenses against the laws relating to the collection of duties; but such penalties shall not be incurred on account of the master not producing to the first boarding officer any of the persons contained in the list who may have been discharged in a foreign country with the consent of the consul, vice-consul, commercial agent, or vice-commercial agent there residing, certified in writing, under the hand and official seal, to be produced to the collector with the other persons composing the crew, nor on account of any such person dying or absconding or being forcibly impressed into other service of which satisfactory proof shall also be exhibited to the collector. (R. S., 4576; Mar. 3, 1897; sec. 3.) Papers relating to crew. The following rules shall be observed with reference to vessels bound on any foreign voyage: _First._ The duplicate list of the ship's company, required to be made out by the master and delivered to the collector of the customs, under section forty-five hundred and seventy-three, shall be a fair copy in one uniform handwriting, without erasure or interlineation. _Second._ It shall be the duty of the owners of every such vessel to obtain from the collector of the customs of the district from which the clearance is made, a true and certified copy of the shipping-articles, containing the names of the crew, which shall be written in a uniform hand, without erasures or interlineations. _Third._ These documents, which shall be deemed to contain all the conditions of contract with the crew as to their service, pay, voyage, and all other things, shall be produced by the master, and laid before any consul, or other commercial agent of the United States, whenever he may deem their contents necessary to enable him to discharge the duties imposed upon him by law toward any mariner applying to him for his aid or assistance.
