Section 237
SEC. 237. Excepting such cases of merchandise as the Insular Collector may by regulation exempt from any or all of the provisions of this section, all package goods, including distilled spirits in casks, must be sent to and received in the warehouse by the shipping marks and numbers, and, if imported without numbers, they are required to be numbered consecutively at the expense of the importer or consignee. Such goods must be gauged, weighed, and in all cases dealt with by such numbers. The collector shall, at the expense of the owner of the goods, cause each package, when received in warehouse, to be marked with the year and month when received, the name of the vessel in which it was imported, and of the place whence shipped, such marking to be done under the supervision of the storekeeper, and the necessary labor to be furnished by the proprietor of the warehouse as a charge on the goods. The shipping marks, numbers, and description of packages must be entered on books to be kept and upon reports to be made by the officer in charge in his daily returns to the collector's office. They shall then be entered in the general warehouse at the custom-house, and the numbers therein given shall be the designated numbers on all permits for withdrawal.
