than one generator. The mine, therefore, continued to be operated at about
50% capacity. 
 Ground was broken for a pilot plant for solvent-refined coal. The 50-ton-per-day
plant is financed by the Office of Coal Research of the Department of the
Interior. Operation of the $18 million plant will be by contract with the
Pittsburgh & Midway Coal Mining Co., a subsidiary of Gulf Oil Corp. The
plant reduces the amount of sulfur and ash in the coal, whereby reducing
air pollution when the coal is burned. The filtered solution produced by
the plant will be vacuum-flash evaported to form combustible prills which
are expected to furnish about 16,000 Btu per pound. Samples of coal from
various U.S. sources will be tested to determine their amenability to the
process. 
 Peat.—Peat was produced in five coun 
ties during 1972, with Thurston County continuing to lead in production.
Snohomish County was second in the State. Production increased about 6% over
that of 1971, but the value per ton increased about 
17%. 
 Petroleum and Natural Gas.—The Washington Water Power Co. reported
natural gas supplies sufficient to supply a growing market for several years.
However, the company implied that future gas supplies inevitably will cost
more. 
 Union Oil Co. of California stopped drilling an apparently unsuccessful
test well near Port Gamble in Kitsap County. Mobile Oil Corp. abandoned a
test well near Kingston, about 7 miles east of Port Gamble. Neither company
announced any findings resulting from the drilling. Standard Oil Co. of California
continued its drilling program in Snohomish County.
