In endeavoring to estimate its character, I am glad to begin with what is clear and beyond question. I refer to the boundaries fixed by the treaty. Commencing at the parallel of 54° 40´ north latitude, so famous in our history, the line ascends Portland Canal to the mountains, which it follows on their summits to the point of intersection with the meridian of 141° west longitude, which it ascends to the Frozen Ocean, or, if you please, to the north pole. This is the eastern boundary, separating the region from the British possessions, and it is borrowed from the treaty between Russia and Great Britain in 1825, establishing the relations between these two powers on this continent. It is seen that this boundary is old; the rest is new. Starting from the Frozen Ocean, the western boundary descends Behring Strait, midway between the two islands of Krusenstern and Ratmanoff, to the parallel of 65° 30´, just below where the continents of America and Asia approach each other the nearest; and from this point it proceeds in a course nearly southwest through Behring Strait, midway between the island of St. Lawrence and Cape Chukotski, to the meridian of 172° west longitude, and thence, in a southwesterly direction, traversing Behring Sea, midway between the island of Attoo on the east and Copper Island on the west, to the meridian of 193° west longitude, leaving the prolonged group of the Aleutian Islands in the possessions transferred to the United States, and making the western boundary of our country the dividing line which separates Asia from America.
