SEA WEED. A species of grass which grows in the sea.
2. When cast upon land, it belongs to the owner of the land adjoining the sea shore; upon the grounds, that it increases gradually, that it is useful as manure and a protection to the ground, and that it is some compensation for the encroachments of the sea upon the land. 2 John. R. 313, 323. Vide 5 Verm. R. 223.
