fathoms, and it is frozen over and full of ice from October to May or 

 June. The middle point of the western boundary (Lonp. 166° W.) is 

 Lat. 63°25' N. 



Ocean Cape. The low SE. entrance to Yakutat Bay. Its position is Lat. 

 .•S9°33' N. and Long. 139°48' W. 



Orca. A salmon cannery in the easternmost portion of Prince William 

 Sound, with shoal water communication with the Pacific Ocean. Its 

 waters are cold from glacial ice in the Sound and streams from the 

 Snow Mountains to the east. Its position is Lat. ()fl°3G' N. and Long. 

 145°40'AV. 



Pinnacles or Pinnacle Rocks. There are several Pinnacle or Priest Rocks 

 in the neighborhood of Unalaska Bay. Those referred to in the text

 and Long. 166°27'W. 



Point Barrow. On the Arctic Coast of Alaska, 210 geographical miles 

 from Bering Strait, following the coast line from point to point. Its 

 position is Lat. 71°22'N. and Long. 156°]2' W. 



Popof Island. The high and rocky island lying east of the NE. point of 

 Unga Island, one of the Shumagin group, the strait between them 

 being not quite a mile wide. Sand Point is the westernmost point. 

 Its position is Lat. 55°20'N. and Long. 160°.33' W. 



Port Clarence. A well protected bay of nearly circular form, 10-12 n. 

 miles in diameter, ESE. 35 n. miles from Cape Prince of Wales. A 

 long, low, narrow spit encircles the bay from S. to W., and then N., 

 nearly to the north shore, under which the entrance lies. The 

 position of Cape Spencer, the end of the spit, is Lat. 65°15' N. and

Prince William Sound. A large area of water and islands in the NW. 

 part of the Gulf of Alaska and 160 n. miles west of Mt. St. Elias. 

 Several large islands protect the seaward part of the sound, but there 

 are three good channels leading into it. From the eastern to the 

 western parts, it is 80 n. miles in breadth, and from the SW. entrance 

 to the mainland west of Port Valdes, it is 70 n. miles. It is notable 

 for many deep fiords, penetrating the mountainous surroundings, and 

 at the heads of most of the fiords, are glaciers, some coming down to 

 the waters edge. Just east of the eastern entrance, the cold waters of 

 the Copper River come down with much detritus in suspension. The 

 waters of this sound are probably much colder than the adjacent 

 waters of the Gulf of Alaska. The towns on the shores of Prince 

 William Sound, at present, are Orca, a canning station in the eastern 

 jiart (cf. al)Ove), Valdes, a mining camp, and Nutchek or Constantin, 

 tlie old Russian trading esta))lishment, near the eastern entrance. The 

 position of the last is Lat. 60''20' N. and Long. ]46°53'W.
