GREAT BRITAIN, 1873. 37] DEFINITION OF THE BOUNDARY-LINE. The chart upon which the boundary-line between the British and the Definition or me United States possessions is laid down is entitled “North America, l>¤¤¤d=¤>‘-ii¤¤- West Coast, Strait of Juan de Fuca, and the channels between the continent .and Vancouver Id, showing the boundary-line between British and American possessions, from the admiralty surveys by Captains H. Kellett, R. N., 1847, and G. H. Richards, R. N., 1858-1862.” The boundary-line thus laid down on the chart is a black line shaded red on the side of the British possessions, and blue on the side of the possessions of the United States. The boundary-line thus deliued commences at the point on the 49th parallel of north latitude on the west side of Point Roberts, which is marked by a stone monument, and the line is continued along the said parallel to the middle of the channel which separates the continent irom Vancouver Island, that is to say, to a point in longitude 1230 19* 15" W., as shown in the said chart. It then proceeds in a direction about S. 500 E. (true) for about fifteen geographical miles, when it curves to the southward, passing equidistant between the west point of Patos Island and the east point of Saturna Island, until the point midway on a line drawn between Turnpoint, on Stewart Island, and Fai1·- fax Point, on Moresby Island, bears S. 680 W., (true) distant ten miles; then on a course south 680 W., (true) ten miles to the said point midway between Turnpoint, on Stewart Island, and Fairfax Point, on Moresby Island, thence on a course about south 120 30' east (true) for about eight and three-quarter miles to a point due east, one mile from the nortbermost Kelp Reef, which reef on the said chart is laid down as in latitude 480 33’ north, and in longitude 1230 15' west; then its direction continues about S. 200 15' east, (true,) six and one-eighth miles to a point midway between Sea Bird Point, on Discovery Island, and Pile Point, on San Juan Island; thence in a straight line S. 450 E., (true,) until it touches the north end of the middle bank in between 13 and 18 fathoms of water; from this point the line takes a general S. 280 30' W. direction (true) for about ten miles, when it reaches the centre of the fairway of the Strait of Juan de Fuca, which, by the chart, is in the latitude of 480 17' north and longitude 1230 14’ 40" W. _ Thence the line runs in a direction S. 730 W. (true) for twelve miles, to a point on a straight line drawn from the light-house on Race Island to Angelos Point, midway between the same. Thcnce the line runs through the centre of the Strait of Juan de Puca, jirst, in a direction N. 800 3U' \V., about 5i} mile to a point equidistant on a straight line between Beeehey Head, on Vancouver Island, and Tongue Point,— on the shore of Washington Territory; second, in a direction N. 760 W., about 13a miles to a point equidistant in a straight line between Sherringham Point, on Vancouver Island, and Pillar Point on the shore of Washington Territory; third, in a direction N. 680 W., about 30;% miles to the Pacific Ocean, at a point equidistant between Bonilla Point, on Vancouver Island, and Tatooch Island lighthouse on the American shore, the line between the points being nearly due north and south, (true.) _ _ _ The courses and distances as given in the foregoing description are not assumed to be perfectly accurate, but are as nearly so as is supposed to be necessary to a practical definition of the line laid down on the chart and intended to be the boundary-line.
