112 THE GRANITES OF MAINE. 
The quarries consist of three openings, the main one of which is 
200 feet square and from 15 to 30 feet deep. 
Rock structure: The sheets, from 1 to 5 feet thick, are horizontal 
with slight undulations. Vertical joints strike X. 65° AY., forming 
headings on the north and south side, also north, and coated in place! 
with pyrite. The rift is horizontal. A vertical dike of aplite 1 foot 
7 inches thick has a X. 10 o -15° W. course. The amount of sap 1 
small. Dark-gray knots up to 2 inches and exceptionally 7 inches 
in diameter occur. 
The product was carted to a wharf a half mile oil' and shipped to 
New York. 
Hooper, Havey <& CoSs quarry is in North Sullivan. Office, NortI 
Sullivan. 
The granite i- a biotite granite of medium-gray shade and line to 
medium even-grained texture, like that of the Crabtree ^ Havel 
quarry (specimen 69, a) described on page 110. 
The quarry, opened in about 1894, measures 300 by 150 feet by 15- 
20 feet in depth. As the bottom of the quarry is about IT) feet below 
tin 1 general surface there is much inflow of water along the sheets, 
as well ;i> direct collection of rain water. Its drainage requires 
considerable pumping. After being idle in winter it requires three 
weeks' steady pumping to reopen it. 
Rock structure: The sheets, from 6 inches to 6 feet thick, are 
gently undulating and horizontal. Vertical joints strike X. 2(1 
25° E., forming the west side of quarry, and also east-west, form™ 
a heading on its north side. The rift i- horizontal, and the grail 
vertical, east-west. The rock i- evidently under a compressive east- 
west strain, as it tends to fracture in a north-south direction across 
the grain, without regard to knox hole-. The knots are small. 
The plant consists of 3 derricks (horse) and 1 -team pump. 
Transportation is by callage of one half mile to wharf. 
The product is random -tone and street material, most I y for Boston. 
Contracts in 1905: Curbing (straight and circular), crossings, and 
paving blocks for Philadelphia. 
The Whalesbach quarry, in North Sullivan. i> operated by \\ T. 
Havey, jr., & Son. of Franklin. 
The granite is a biotite granite of medium-gray shade and fine 'to 
medium texture, like that of the Crabtree and Havey quarry described 
on page 110. 
The quarry, opened in about 1868, is 200 feet square and from 8 
to 30 feet deep. It is drained by a 2^-inch siphon pipe. 250 feet long. 
The stripping consists of 3 to 8 feet of drift. On one side the glaci- 
ated granite surface has a 2J-foot bowlder, excavated from the over- : 
lying drift, resting on it.
