Goods cast into the sea tied to a buoy, so that they may be found again by the owners, are so denominated. When goods are cast into the sea in storms or shipwrecks, and remain there, without coming to land, they are distinguished by the barbarous names of “jetsam,” “flotsam,” and “ligan.” 5 Coke. 108; Harg.
