Whenever in any proceeding relating to seamen's wages it is shown that any seaman or apprentice has, in the course of the voyage, been convicted of any offense by any competent tribunal, and rightfully punished therefor, by imprisonment or otherwise, the court hearing the case may direct a part of the wages due to such seaman not exceeding fifteen dollars, to be applied in reimbursing any costs properly incurred by the master in procuring such conviction and punishment. (R. S., 4605.) Advances and allotments of wages. (_a_) It shall be, and is hereby, made unlawful in any case to pay any seaman wages in advance of the time when he has actually earned the same, or to pay such advance wages, or to make any order, or note, or other evidence of indebtedness therefor to any other person, or to pay any person, for the shipment of seamen when payment is deducted or to be deducted from a seaman's wages. Any person violating any of the foregoing provisions of this section shall be deemed guilty of a misdemeanor, and upon conviction shall be punished by a fine of not less than $25 nor more than $100, and may also be imprisoned for a period of not exceeding six months, at the discretion of the court. The payment of such advance wages or allotment shall in no case except as herein provided absolve the vessel or the master or the owner thereof from the full payment of wages after the same shall have been actually earned, and shall be no defense to a libel suit or action of the recovery of such wages. If any person shall demand or receive, either directly or indirectly, from any seaman or other person seeking employment, as seaman, or from any person on his behalf, any remuneration whatever for providing him with employment, he shall for every such offense be deemed guilty of a misdemeanor and shall be imprisoned not more than six months or fined not more than $500. (_b_) It shall be lawful for any seaman to stipulate in his shipping agreement for an allotment of any portion of the wages he may earn to his grandparents, parents, wife, sister, or children. (_c_) No allotment shall be valid unless in writing and signed by and approved by the shipping-commissioner. It shall be the duty of the said commissioner to examine such allotments and the parties to them and enforce compliance with the law. All stipulations for the allotment of any part of the wages of a seaman during his absence which are made at the commencement of the voyage shall be inserted in the agreement and shall state the amounts and times of the payments to be made and the persons to whom the payments are to be made. (_d_) No allotment except as provided for in this section shall be lawful. Any person who shall falsely claim to be such relation, as above described, of a seaman under this section shall for every such offense be punished by a fine not exceeding $500 or imprisonment not exceeding six months, at the discretion of the court.
