1911 Encyclopædia Britannica/Cargo
CARGO (Span. for “loading,” from Lat. carrus, car), a shipload, or the goods (or even, less technically, persons) carried on board a ship; and so, by analogy, a term used for any large amount. The maritime law affecting the cargo of a ship is dealt with in the articles Average, Affreightment, Insurance, Salvage, Bottomry, Lien; and the specialities of cargo-ships under Ship.
