The name Puget Sound was originally given by Vancouver to that portion of these inland arms of the sea which lies south of the Narrows near Tacoma. Vancouver distinguished two other main portions of these inlets; Hoods Canal and Admiralty Inlet. His usage was respected by Wilkes of the United States Exploring Expedition a half century later, but today the term Puget Sound embraces all three portions and is ftc quently used to include all marine waters connected with the Strait of J uan de F uca south of the International boundary line. In this broad sense it is used in the title of this paper.
