QUARRTES IN HANCOCK COUNTY. Ill 
The Hopewell quarry is in the town of Sullivan, on Sullivan River 
above the " falls." Operator, Hopewell Stone Company, 36 Main 
street, Bangor, Me. 
The granite (specimen 68, a) is a biotite granite, of light to me- 
dium-gray shade and fine to medium even-grained texture, consist- 
ing, in descending order of abundance, of milk-white potash feld- 
spar (microcline and orthoclase), smoky quartz, translucent white 
soda-lime feldspar (oligoclase), and black mica (biotite). together 
with accessory magnetite. Many slender oligoclase crystals, most of 
hem unaltered, measure between one-tenth and one-fifth inch. The 
:ontrasts are not strong. The stone takes a good polish, and the 
contrast between polished and cut face is fair. The general shade of 
his granite is but a trifle darker than the so-called " white granite " 
3f North Jay. described on page 80, but its mineral particles are. 
joarser and its biotite is more conspicuous. 
The quarry, opened about 1855, is triangular in area, each side 
seing about 200 feet long; the depth of the working face on the east 
s 40 feet, and the depth at front 20 feet. There ; s no drainage 
>roblem. The stripping consists of 2 feet of drift besides 6 feet of 
j top " or poor stone. 
Rock structure: The sheets, from 2 to 12 feet thick, dip south wesl 
it a low angle. Vertical joints strike X. 25°-30° E., forming a 
leading on the north, and also N. 60° W., the last recurring at irregu- 
ar intervals and more or less discontinuously. The rift is horizontal 
nd the grain vertical, with course X. (>0° W. There is very little 
ap. Knots are few and small. 
The plant consists of three derricks and two engines. 
transportation is effected by gravity tracks and cable to wharf 
'00 feet off. Schooners of V>\ feet draft can pass the falls at high tide 
luring one-half hour. 
The product is random blocks, curbing, and crossings for Phila- 
lelphia, Boston, and New Jersey. The thin sheets and waste go into 
>aving blocks. Contract in 1905: Base course of manual training 
chool building, corner Broad and Jackson streets, Philadelphia. 
Tlie Stimson quarries are in the town of Sullivan. Owner, Mrs. 
C. A. Stimson, Sullivan. Leased by Hopewell Stone Company, but 
jot operated in 1905. Reported as sold since the writer's visit. 
The granite (specimen 67, </) is a biotite granite of medium-gray 
hade and fine to medium even-grained texture, consisting, in descend- 
lg order of abundance, of gray potash feldspar (orthoclase and 
licrocline), smoky quartz, grayish soda-lime feldspar (oligoclase), 
nd black mica (biotite), together with accessory magnetite. The 
Biotite plates measure up to 0.15 inch across. The general shade of 
Lis granite is darker than that of the Hopewell quarry. Contrasts 
re slight, owing to similarity in shade of quartz and feldspar,
