REVIEW BY ISLANDS 
 
 American Samoa.—Beach sand, basalt rock, coral, and volcanic cinders
were produced by crews of the Government of American Samoa for use in various
building and paving projects. A rock crusher and concrete and asphalt batch
plants were operated at the Tafuna Public Works 
 
 Guam.—Crushed coral limestone and coral fines were processed by commercial
producers and government construction crews and used as base material and
concrete aggregate. Much of the year's total output was consumed in building
roads for residential subdivisions and in construction of typhoon-resistant
homes. 
 Wake.—Fingerlike coral was dredged at Wake Island and processed in
a 300-tonper-day portable crusher. The crushed coral aggregate was used in
several construction projects, the largest of which 
junction with a refinery. Hess operates on St. Croix and will export to the
mainland a maximum of 15,000 barrels of finished products per day. 
Compound. Production of volcanic cinders increased during 1967 after tests
proved it to be an economical substitute for basalt rock which had to be
drilled and blasted. Cinder aggregate was used in about 80 percent of the
concrete and concrete products and for all of the asphalt paving. 
was the addition of a new taxiway paralleling the existing airfield runway.

 Other Pacific Island Possessions.—No mineral production was reported
on the islands of Canton, Enderbury, Jarvis, Johnston, Midway, and Palmyra.
The National Aeronautics and Space Admini~ stration closed its small Gemini
tracking station on Canton. Mineral material requirements for construction
and rehabilitation projects on Johnston and Midway were obtained from stockpiles
of previously quarried coral or supplied by contractors from Hawaii and the
U.S. mainland. 
 
TRUST TERRITORY OF THE PACIFIC ISLANDS 11 
 The Trust Territory of the Pacific Islands consists of more than 2,100 islands
and atolls in the Western Pacific, scattered over an ocean area roughly the
size of the continental United States. Mineral production was confined to
the quarrying of volcanic rock and coral used mainly for construction of
medical and educational buildings, housing units, and maintenance of roads.
Although deposits of phosphate 
rock and bauxite exist on several of the islands, neither of these minerals
was mined during 1967. Inhabitants continued to oppose large-scale mining
operations, fearing that such operations might contamfnate ground water and
destroy land used for subsistence farming.
