By another channel we may trace the course of the ideas which converged and culminated in the claims of Charles to the dominion of the surrounding seas--viz., in connection with the development of the law relating to the rights of property in the foreshore and the bed of the sea. Cases frequently occurred in which those rights were contested between private individuals and the crown; and in the course of litigation, or in writings dealing with the subject, the rights in the sea which were alleged to belong to the crown were explained. We have already seen that Plowden, in a case of the kind, argued that Queen Elizabeth possessed jurisdiction as far as the middle line in the surrounding seas,--a doctrine which the queen expressly repudiated in 1602,--but denied to her any right of property in either the sea or its bed. The claims of the crown to the ownership of the foreshores originated in the reign of Elizabeth; under James and Charles I. they were systematically pursued by the “title-hunters”; and while the legal decisions in contested cases were for a long time adverse to the crown, they began in the reign of James to be in its favour, and gradually the idea was imported into and became a part of English law that the ownership of the foreshore was _prima facie_ vested in the crown in virtue of the royal prerogative.[649] Along with the development of this idea came another, which was ultimately likewise engrafted on English law--that the crown had the exclusive right of property in the sea and in the soil beneath it. The origin of the idea is to be found in a treatise written in 1569 by Thomas Digges.[650] He argued that as many things--as wrecks, treasure-trove, waifs and strays, which were originally common by the law of nature--now belonged to the Prince, so also should the sea, which was the chief of all waters, and could not by the civil law become the property of a subject. He held that just as the owners of the soil had the property in a river and its banks, the king had the interest and property in the “great salt river” environing the island, and in its shores and bottom; and he speaks of the sea as the “King’s river,” the “King’s streme,” and the “King’s water,” in which he had also jurisdiction. Digges also claimed that the fishings in the sea belonged to the crown, for “although the Kings of England have benne content to suffer fishermen _Jure gentium_ to enjoy to theire owen use such fishe as by theire charges travill and adventure they can in the Englishe Seas take, Yet haue the Kings of England for remembrance of this theire favoure that the memorie of theire propertie in the Seas shoulde not be extinguished, alwaie reserved to them selves the cheif fishe as Sturgeon, Whale, &c.”[651]
