IV, With reference to the Hne of demarcation laid down in the 

 preceding article, it is understood — 



1st. 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 Frozen 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 ot 

 193 degrees west longitude, so as to include in the territory con- 

 veyed the whole of the Aleutian islands east of that meridian.
