quartz in particles that are circular in cross section and is partly 
altered to a white mica and the biotite to chlorite. 
The stone takes a good polish, but the large size of the biotite scales 
is not favorable to the durability of the polish in outdoor exposure. 
The contrasts are chiefly between the grayish -pinkish ground and the 
black mica. 
The openings are small. The stripping consists of 3 feet of sand. 
The sheets, from 1 to 3 feet thick, are horizontal. Vertical joints 
strike N. 10° E. and N. 70° W. The rift is horizontal. Sap 2 inches 
thick occurs along the sheets. 
STATISTICS OF EQUIPMENT AND INVESTMENT. 
In order to ascertain the amount of capital invested in the Maine 
granite industry, the operators were asked to submit, in confidence, 
conservative estimates of the value of their quarries and plants 
and of an amount of capital sufficient for working the same on their 
present scale. Figures were obtained from all but a few very small 
concerns, and in their cases estimates were made by the writer based 
on the size of the quarries and plants and the number of men 
employed and on the returns from the other firms. The figures for 
82 operators aggregate $3,531,000, but four of these operators are 
simply owners of idle quarries. As their value was estimated at 
$73,500, that amount should perhaps be deducted from the aggregate, 
which would make the investment represented by the Maine granite 
industry $3,467,000, or, in round numbers, $3,500,000.
