vanish altogether, at least as a thing to be regarded in international affairs. In the earlier records in which the sea is referred to in connection with English law or jurisdiction, it is evident that a certain part was held to appertain to the crown. In an article in the _Black Book of the Admiralty_ which is ascribed to the reign of Henry I. (A.D. 1100-1135), reference is made to “the sea belonging to the king of England”; in John’s ordinance of 1201 the term was simply “the sea” (_la mer_), but very commonly it was “our sea,” or the “sea of England,” or “the sea under the dominion or jurisdiction of the king”; while the declaration is often made that the kings of England are lords of the sea or of the English sea.[5] Similar phrases were used in later times. Thus Queen Elizabeth spoke of “our seas of England and Ireland,” and James of “his seas” and “streams,” as did also Charles I.; and such terms as “the adjacent sea,” the “environing seas,” the “ambient seas,” and “the seas flowing about the isle,” were not uncommonly used.[6] Still more common and scarcely more definite was the term the “Four Seas of England,” or simply the “Four Seas,” which was employed as early as the thirteenth century in law books, statutes, and official documents, as indicating the boundaries of the realm in connection with legal proceedings. Within the four seas (_infra_ or _intra quatuor maria_; dedeinz les quaters meers) was to be within the realm; and without the four seas (_extra quatuor maria_, oultre les quaters meers) was to be without the realm.[7] In the seventeenth century, when the English pretension to the sovereignty of the sea was at its height, Coke, Selden, Prynne, and others maintained that to be on the four seas, as well as within them, was to be within the realm, under the jurisdiction of the Admiralty, and this doctrine was held, at least formally, as late as 1830.[8] Rarely the “Three Seas” are mentioned,[9] and less rarely the “Two Seas,” by which was meant the two arms of the sea passing respectively between England and France, and England and Flanders, and corresponding to one of the meanings of the Narrow Sea.
