Three geological divisions, analogous to those of New Zealand, are 

 recognized : — 1. Serpentine rocks, forming the chief framework of the 

 island ; 2. A patch of crystalline and ancient rocks in the N. and X.E. ; 

 3. Metamorphic and newer deposits, associated with igneous rocks 

 (melaphyre), chiefly on the W. coast. Gold and copper occur in 2 ; 

 iron, chromium, and nickel in 1 ; and there is coal, probably Liassic, 

 on the W. coast. G. A. L.

 Most of the islands are of volcanic origin, with signs of upheaval, 

 in the form of coral-blocks cropping up inland. There are no barrier- 

 reefs ; but the islands are surrounded by fringing-reefs. E. E., Jun.

 Torres Straits is dotted with islands of volcanic and coral origin. 

 Mt. Cornwallis Is., 5 miles from the New Guinea coast, is covered 

 with granite boulders. Of the Polynesian islands, the following are 

 specially noticed as being of volcanic origin and usually surrounded by 

 coral-reefs : — Kepple Is., 400 ft. high ; Nina or Good Hope Is., 

 of the Eriendly group, is composed entirely of black lava, with a lake, 

 6 miles in circumference, in an extinct crater ; volcanic phenomena are 

 still at times active. Uea or Wallis Is., about 700 ft., is surrounded 

 by a reef. One of the Fortuna Islands, between Wallis Is. and the 

 Eiji islands, rises to 2000 ft. The Torres group, of 4 chief and a few 

 small islands, are of coral-volcanic origin. Star Is. rises as a vol- 

 canic cone, 2900 ft., with an extinct crater at the summit. Blight Is. 

 possesses the remains of an extinct crater. Ambrym Is. is an active 

 volcano, 3000 ft. high. Lopevi Is., also active, is 5000 ft. high. The 

 active volcano on Tauna Is. is described. The Ellice group consist of 

 scattered islands of coral origin, as are the Nukufute or De Peyser 

 islands, Egg or Netherland Is., and Hudson Is. Volcanic rocks are the 

 predominating feature along the newly discovered part of the E. coast 

 of New Guinea and outlying islands. At Port Moresby the hillside 

 is covered with granite boulders and quartz ; gold was also found 

 here. On the N.E. shore of New Guinea there is no outlying barrier
