Section 47
SEC. 47. Night inspectors are appointed for the purpose of preventing smuggling. They are required to keep a vigilant watchover the vessels, stores, or merchandise whose custody is committed to them, in order to prevent the landing between sunset and sunrise of any merchandise from any vessel, unless the same is done by proper authority and under the supervision of a discharging inspector, and to protect the bonded stores and merchandise from robbery or the unlawful removal of merchandise therefrom or from any wharf or place on which the same may be deposited. Whenever cargo is being discharged from any vessel at night, under the supervision of an inspector, the night inspector assigned to such a vessel shall not interfere with such landing so long as the inspector is present in charge thereof, but night inspectors are authorized to demand to see, and the inspector is required to exhibit, the night permit for the working of the vessel. If merchandise is landed from the vessel when no inspector is present, the night inspector shall stop the landing and report the fact the next day to the surveyor or other proper officer.
