88 THE GRANITES OF MAINE. 
The Howard quarry is in the town of Bluehill, 1 mile southeast of 
top of Bluehill and \\ miles northeast of Bluehill village. Owner, 
William M. Howard, Bluehill. 
The granite is a biotite granite like that of the White quarry. 
The quarry is about 50 feet square and from 5 to 15 feet deep. 
The sheets, 8 feet thick, dip 40° N. The rift is vertical with a 
strike of X. 10° W. Sap is 3 inches thick on each side of sheets. 
The plant consists of one baud derrick. The stone is carted one- 
half mile, where it is cut and polished. The product is used locally 
for monuments. 
Some of the stone of the gate house to High Bridge, in New York, 
came from this quarry, and also several soldiers' uionuments. 
The Bucks Harbor quarries, Bucks Harbor, South Brooksville, are 
operated by the Bucks Harbor Granite Company. 
The granite (specimen 46, <i) from opening one-half mile south- 
east of South Brooksville, is a biotite granite of light grayish-buff 
color with conspicuous black mica, and is of coarse (inclining to 
medium) even-grained texture. It consists, in descending order of 
abundance, of a light cream-colored potash feldspar (microcline and 
orthoclase), smoky quartz, a milk-white soda-lime feldspar (oligo- 
clase), and black mica (biotite) with accessory magnetite. The 
oligoclcase is partially altered to kaolin and a while mica. A little 
pyrite was found at the quarry. 
The granite (specimen 47, a) from opening one-fourth mile north- 
east of South Brooksville. is of medium-gray shade, with conspicu- 
ous black mica and coarse, even-grained texture, and consists, in 
descending order of abundance, of a very light gray potash feldspar 
(microcline and orthoclase), slightly smoky quart/, a little soda- 
lime feldspar (oligoclase), and black mica (biotite), Both of these 
granites are bright from the contrasts of their minerals. 
The quarries consist chiefly of two openings — one formerly operated 
by the Wilson Granite Company, and lying one-half mile southeast 
of the village, measuring 200 feet by 100 feet, and from 5 to 20 feet 
in depth; the other, one-fourth mile northeast of the village, is 
about 200 by 100 feet, and from 5 to 10 feet deep. 
Rock structure: The sheets at these quarries are from 2 to 8 feet 
thick and are either horizontal or dip 10°-15° W. Joints at the 
first opening strike N. 40° W., dip 75° S. W., and recur at intervals 
of 15 feet or more; also X. 50° E., dipping 75° S. 50° W. to 90°. 
The rift is vertical, striking N. 30° E. The sap is confined to the 
uppermost sheets. 
The plant consists of 3 derricks and 1 hoisting engine. 
Transportation: The company owns two granite wharves, which 
afford 12 feet of water at low tide.
