THE GRANITES OF MAINE. 
are horizontal or dip 30° E., but irregularly. A basic dike 10 inches 
thick forms the northwest side of the quarry and is said to continue 
for one-fourth mile in a direction N. 50° E. The joints run in four 
directions, none of them at right angles to another and none of them 
vertical. Sap measures from 3 to 6 inches thick along the sheets. 
Knots up to 6 inches thick are not abundant. 
The plant consists of 6 derricks, 2 hoisting engines, 2 steam drills, 
and 2. steam pumps. 
Transportation involves cartage of one-third mile to a siding on 
the Boston and Maine Railroad. 
The product is used mostly for bridge work. Specimen structures: 
The gateway at Hope Cemetery, in Kennebunk (except the balls on 
the posts) and the Renwick tomb at cemetery near Kittery, Me. 
Contract in 1 ( .M);>: Railroad bridge at Haverhill, Mass.

The Lord prospect is in the town of Wells about 1 mile east-north- 
east of Wells Depot on the Boston and Maine Railroad (eastern divi- 
sion), near a schoolhouse at a road fork. Owners: Granville W.

The granite from the firsl opening (specimen L38, o) is a biotite 
granite of light pinkish-gray shade, with sparsely disseminated con- 
spicuous biotite. and of medium to coarse, even-grained texture, with 
feldspars up to one-half inch and biotite scales up to one-fifth inch in 
diameter. It consists, in descending order of abundance, of a deli 
eatc pink potash feldspar (microcline and orthoclase), with slightly 
smoky quartz, cream- white soda-lime feldspar (oligoclase), and black 
mica (biotite), together with accessory magnetite and zircon and 
secondary white mica and chlorite. The potash feldspars are both 
intergrown with plagioclase. The oligoclase is intergrown with
