178 THE GKANITES OF MAINE. 
60° SW., and forms the northeast and southwest walls, and recurs at 
intervals of from 2 to 10 feet or more; D dips 65° E., and occurs 
exceptionally. The rift is vertical, N. GO W. ; grain is horizontal. 
On the southeast wall there is a basic dike up to 1 foot thick and 
nearly parallel to joints A. Black knots occur up to 6 inches across. 
San measures 6 inches on both sides of upper sheets but diminishes 
below. 
The plant consists of 5 derricks, 2 hoisting engines, and 2 polishers, 
run 1>\ an 8-horsepower engine. 
Transportation involves cartage of 1 mile to railroad. 
The product is used for buildings and monuments, and finds a mar- 
ket in the State and also in the West. Specimen monument: The 
Lincoln monument, erected at Springfield, 111., in 1868. Contract inj

The Marcille <t- Wormwood quarry is in the town of Biddeford, 1J 
miles southwesl of Biddeford city, in West Biddeford. Operator, 
Marcille & Wormwood, Biddeford. 
The granite (specimen L30,<z) is a biotite granite of general medium- 
gray pinkish-buff dolor and of coarse, even-grained texture, with feld- 
spars up to three-fourths inch and biotite up to three-twentieths inch. 
It consists, in descending order of abundance, of a pinkish-buff potasl 
feldspar (microcline and orthoclase ) . dark smoky quartz, cream-white 
soda-lime feldspar (oligoclase), black mica (biotite), and a very little 
muscovite, together with accessory magnetite and secondary epidote, 
chlorite, kaolin, and white micas. The oligoclase is considerably 
altered to kaolin, a white mica, and epidote, and the biotite to chlo- 
rite. The contrasts in this stone arc chiefly between the pinkish-bun 
and the white feldspars and the smoky quartz, to which the black 
mica add- another element. As some of the potash feldspars are 
more pink and others more buff, it has in all live colors and shades. \ 
The quarry is 40 by 20 feet and from 6 to 8 feet deep; There is 
little or no stripping. 
Rock -tincture: The sheets, 7 feet thick (increasing to 15 feet lower 
down the hill), are crossed by vertical or very steep joints, striking 
N. 80°-85° W., which recur at intervals of 20 feet, also striking 
X. 40° E., and recurring at intervals of 35 feet with headings. Sap, 
1 to 2 inches thick, occurs along the top sheet, but along the headings 
it is 4 inches thick. A bunch of knots up to 8 inches thick and of 
egg-shaped outline was noticed. 
The plant consists of 3 derricks. 
Transportation involves a cartage of 1 mile to railroad siding. 
The product is used for buildings. Specimen building: The trim- 
mings on St. Joseph's Church, at Biddeford. (Material for the 
Charlestown, Mass., dry dock was quarried at an old opening adjacent
