and quarrymen often designate as granite widely different rocks 
which may serve more or less similar purposes. Thus in the Adir- 
ondacks not only granite, but syenite, anorthosite and various 
gneisses have been quarried and sold as granite. The broader usage 
will be followed here, so as to include practically all the crystalline 
silicate rocks, with the exception of trap which, owing to its some- 
what specialized industrial features, will be treated by itself. 
Granites and their igneous associates have a wide distribution 
in the Adirondacks and are represented rather extensively in the 
Highlands and.in Westchester county. Some account of their dis- 
tribution and present development for commercial use will be found 
in the preceding issue of this report. It may be said that the quarry 
industry in most localities is in a backward condition, neither com- 
mensurate with the resources which are sufficiently varied to meet 
most requirements for structural and ornamental granite, nor with 
the large local markets which exceed those of any state in impor- 
tance. As a consequence, most of the building, monumental and 
ornamental granite for current use comes from the larger and 
better equipped quarries in New England and the southern states. 
The production of granite for the last three years is shown in 
the accompanying table. The figures are compiled from reports of 
quarries operated for commercial purposes, but do not include the 
output by contractors on road improvement work, as such produc- 
tion is difficult to tabulate. The output in 1912 had a value of 
$202,096, against $148,633 in the preceding year and $244,763 in_ 
1910. The largest item in the total was represented by building 
stone with a value of $65,487, followed by crushed stone valued 
at $49,307, rubble and riprap valued at $27,861 and monumental 
stone valued at $19,130. The granite sold for various other pur- 
poses was valued at $40,311.
