102 THE GRANITES OF MAINE. 
The quarry, opened in 1902, consists of two adjacent openings on 
the northeast side of a northwest-southeast ridge over one-fourth mile 
long and about 50 feet high. These openings measure 60 by 25 feet 
and 35 feet in depth and 50 by 20 feet and 20 feet in depth, respec- 
tively. 
Rock structure: The upper 8 feet of the working face are traversed 
by light -gray more feldspathic bands from one-fourth to 2 inches in 
thickness, constituting a How structure parallel to the sheets, which 
are from 1 to 6 feet thick and dip about 15 SW. Vertical joints, 
striking northeast-southwest, cross the ridge at intervals from I 
inches to 7 feet, and form a heading in the smaller northwesterly 
opening. The rift is parallel to the sheets. As will he noticed by I 
comparing the descriptions of the rock structure at the other black- 
granite quarries, the structure along this ridge is unusually favorable 
for quarrying. 
The plant consists of 1 power and 1 hand derrick and 1 engine 
and 1 steam drill. 
Transportation is effected b\ cartage of 5 miles to Baring on the 
Washington County Railroad. 
The quarry was not in operation in L905. 
The product is used for tablets and monuments, and has found a 
market in New York. Boston, Philadelphia. Baltimore, Virginia] 
Nebraska, Dakota, and California. 
Specimen monuments: A monument erected by Stephen A. Love- 
joy, of Melrose, Ma—., at Melrose Cemetery; also several monument 
at the cemetery in Calais, Me. 
The Tarbox black-granite quarry is in the town of Baileyvilla 
about 900 feet northeast of the Hall quarry described above, at the 
north a\^v of Meddybemps Lake. 5 miles southwest of Baring, on 
the Washington County Railroad, and about 7 miles southwest of 
Calais. Lessee, ( ). S. Tarbox, Redbeach, Me.; owner of mineral 
right, F. H. Hall. Calais. 
This rock is a norite identical with that of the Hall quarrfl 
described above. It appears to belong to an outcrop northeast and 
parallel to the ridge referred to. 
The plant consists of 1 derrick. 
Gardner's black-granite />r<>s/>r<f i> in the town of Calais, on St. 
Croix River, 6 miles south of Calais, north of road to Redbeach. 
Owner. Lorenzo Gardner, Calais, Me. 
This rock (specimen loo. a) is a quartz diorite of very dark gray 
(not bluish) shade and fine, even-grained texture, consisting, in 
descending order of abundance, of a whitish soda-lime feldspal 
(andesine) considerably altered to a white mica, hornblende partly 
altered to chlorite, quartz, black mica (biotite), and magnetite, 
together with accessory titanite, pyrite, apatite, and secondary cal-
