_Third._ Every agreement entered into before a shipping-commissioner shall be acknowledged and certified under the hand and official seal of such commissioner. The certificate of acknowledgment shall be indorsed on or annexed to the agreement; and shall be in the following form: "State of ————, County of ————: "On this ———— day of ————, personally appeared before me, a shipping-commissioner in and for the said county, A. B., C. D., and E. F., severally known to me to be the same persons who executed the foregoing instrument, who each for himself acknowledged to me that he had read or had heard read the same; that he was by me made acquainted with the conditions thereof, and understood the same; and that, while sober and not in a state of intoxication, he signed it freely and voluntarily, for the uses and purposes therein mentioned." (R. S., 4512.) Section 4511 shall not apply to masters of vessels where the seamen are by custom or agreement entitled to participate in the profits or result of a cruise or voyage, nor to masters of coastwise nor to masters of lake-going vessels that touch at foreign ports; but seamen may, by agreement, serve on board such vessels a definite time, or, on the return of any vessel to a port in the United States, may reship and sail in the same vessel on another voyage, without the payment of additional fees to the shipping-commissioner. [NOTE.—Sec. 4511, however, does apply in part to masters of coastwise vessels whose crews are shipped under provisions of the act of Feb. 18, 1895.] (R. S., 4513; Feb. 18, 1895; June 19, 1886.) The master shall, at the commencement of every voyage or engagement, cause a legible copy of the agreement, omitting signatures, to be placed or posted up in such part of the vessel as to be accessible to the crew; and on default shall be liable to a penalty of not more than one hundred dollars. (R. S., 4519.) Period of engagement. A master of a vessel in the foreign trade may engage a seaman at any port in the United States, in the manner provided by law, to serve on a voyage to any port, or for the round trip from and to the port of departure, or for a definite time, whatever the destination. The master of a vessel making regular and stated trips between the United States and a foreign country may engage a seaman for one or more round trips, or for a definite time, or on the return of said vessel to the United States may reship such seamen for another voyage in the same vessel, in the manner provided by law, without the payment of additional fees to any officer for such reshipment or re-engagement. (June 26, 1884; sec. 19.) Penalty for shipment without agreement.
