7. The Collectors take care that all the goods, on which Congress has imposed a duty, pay the amount due. To this end he often requires one or more deputies. The entire commerce of the part of the country falling in his district, with other countries, passes under his examination. He receives all reports, manifests, and documents required to be exhibited by all vessels, domestic and foreign, on their entry into his port, and all accounts of all the goods they have on board. On these he must estimate the duties, receive the moneys, or bonds securing their payment, and grant all permits for landing the goods. He transmits, quarterly, all the moneys collected in his department, with an accurate account of all the transactions of his office during the quarter, to the Secretary of the Treasury. These accounts pass to the Customs bureau, and the money to the Treasurer of the United States. 8. His duties, as described in the previous section, make him acquainted with all the imports of the country, in his District or Port. He is also required to examine the manifests of all the vessels, and the accounts of their cargoes, that leave his port for a foreign country. This secures a knowledge of all the exports of the country. It is his duty to give clearances, or permits, to all vessels leaving for foreign ports. It is unlawful for any vessel to depart without this document. A ship’s clearance can be properly given only when her manifest, or detailed account of the quantity, kind, and value of her cargo is ascertained to be correct. 9. We give the form of a ship’s Manifest, and also of a Clearance. A SHIP’S MANIFEST. “Report and manifest of the cargo laden on board of the ____, whereof ____ is master, which cargo was taken on board at the port or ports of ____, burthen ____ tons, built at ____, in the State of ____, and owned by ____, merchants at ____, and bound for ____.” This, together with a particular description of the marks and numbers of every bale, box, case, barrel, bundle or parcel on board of the vessel, is the manifest. It must be given to the collector of whatever port the vessel arrives at; and the master of her must swear that it is in all respects a true and accurate account of all the cargo on board, to the best of his knowledge and belief.
