This document, made up generally by the ship's broker, from the contents of the bills of lading, contains a specification of the nature and quantity of the cargo laden, and is generally attested officially, and in some countries notarially. The prize laws seldom mention this paper ; nor is it general ; but yet of essential importance in case of search, as well for belligerents, as for neutrals in procuring a speedy dismissal. It is usual to require it at the custom house.[1]
