IV. With reference to the line of demarcation laid down in the 
preceding article, it is understood— 
ist. That the island called Prince of Wales Island shall 
belong wholly to Russia (now, by this cession, to the United 
States). 
2d. That whenever the summit of the mountains which extend 
in a direction parallel to the coast from the 56th degree of north 
latitude to the point of intersection of the 141st degree of west 
longitude shall prove to be at the distance of more than ten 
marine leagues from the ocean, the limit between the British 
possessions and the line of coast which is to belong to Russia as 
above mentioned (that is to say, the limit to the possessions ceded 
by this convention) shall be formed by a line parallel to the 
winding of the coast, and which shall never exceed the distance 
of ten marine leagues therefrom. 
The western limits, within which the territories and dominion 
conveyed are contained, passes through a point in Bering Straits 
on the parallel of 65 degrees 30 minutes north latitude, at its 
intersection by the meridian which passes midway between the 
islands of Krusenstern, or Ignalook, and the island of Ratmanoff, 
or Noonarbook, and proceeds due north, without limitation, into 
the same f rozen Ocean. The same western limit, beginning at 
the same initial point, proceeds thence in a course nearly south¬ 
west through Bering’s Straits and Bering’s Sea, so as to pass mid¬ 
way between the northwest point of the Island of St. Lawrence 
and the southeast point of Cape Choukotski, to the meridian of 
172 west longitude; thence, from the intersection of that merid¬ 
ian, in a southwesterly direction, so as to pass midway between 
the island of Attou and the Copper Island of the Kormandorski 
couplet or group in the North Pacific Ocean, to the meridian of 
193 degrees west longitude, so as to include in the territory con¬ 
veyed the whole of the Aleutian islands east of that meridian.
