Summary

A ship captain leaving the United States for foreign ports must not take on board or carry any letter that started in the U.S. if the letter did not go through a U.S. post office or if it is not about the ship's cargo, unless section 601 allows it. The port officer who clears the ship must make the captain swear he does not have and will not take such letters. When a ship comes back to a U.S. port, the captain must turn in any letters that did not go through the mail to the local post office, unless section 1699 of title 18 says otherwise.
