151 
Transportation is effected by cartage one-fourth mile to a siding 
of Somerset Railroad. 
The product is used mainly for buildings. Specimen buildings: 
The post-office at Muskegon, Mich. ; the Merrill Library at Norwood, 
Mass. ; the Catholic Church at Lewiston, Me., and the court-house 
at Bangor, Me. Contract in 1905 : Annex to insane asylum at 
Augusta, Me. 
The Lawton quarry is in the town of Norridgewock, on the north- 
west side of Dodlin Hill and 2 J miles south-southwest of Norridge- 
wock. Operator, F. S. Lawton, Norridgewock. 
The rock is a quartz monzonite of medium-gray and light-gray 
shade and medium and porphyritic texture, identical with that of 
the Dodlin quarry just described. 
The quarry, opened before 1845, consists of two openings measur- 
ing 200 by 100 and 300 by 
200 feet by from 5 to 10 
feet in depth. The loam 
stripping does not exceed 
3 feet. 
Rock structure : The 
same flow structure occurs 
as at Dodlin quarry, on 
the other side of the hill. 
The sheets, up to 5 feet 
thick, average from 3 to 4 
feet and roll over the hill 
with a dip of 10° both 
north and south. Between 
some of the ordinary 
sheets there are unusual 
ones, one-half inch in 
thickness, which in large slabs are flexible. Whether this was in 
part due to incipient disintegration was not determined. The len- 
ticular form of the sheets gives them the appearance of being very 
irregular in thickness. Vertical joints, striking N. 60°-65° E., recur 
at intervals of 10 to 50 feet. The rift is horizontal and grain vertical, 
with course N. 00° E. Knots, both light and dark, are rare. Sap 
occurs along the sheets up to 6 inches in thickness. There is a 6-inch 
dike of white aplite striking N. 80° W., glaciated with the granite at 
the surface (specimen 116^, c). 
The plant consists of 3 hand derricks. 
Transportation involves a cartage of 3 miles to railroad at Nor- 
ridgewock. 
The product is used for buildings, bridges, and monuments to sup-
