a decrease for the preceding year of $737,940 or 12 per cent. It 
should be noticed that the totals as given are not inclusive of slate, 
millstones or limestone used for cement manufacture, which are 
reported separately. 
Of the different branches of the industry represented in the State, 
the granite trade showed a slight improvement, increasing from 
$148,633 in Ig11 to $202,086 last year. The yield, however, was 
below the average of earlier years. 
The limestone quarries contributed more than one-half of the 
total for the year, with a product valued at $3,510,495. The figures 
for IQII were $3,174,161. The use of limestone for crushed stone 
accounts for its predominant importance, though it is also largely 
employed for lime making, furnace flux, and for building stone. 
There was a slight falling off in the value of the marble quarried 
which amounted to $241,847, against $278,041 in the preceding 
year. The decrease was in the building stone supplied by the south- 
eastern New York quarries. 
The sandstone quarries contributed an output valued at $1,280,743 
against $1,060,106 in 1911. The increase of about 20 per cent did 
not restore the industry to the high level reached a few years ago, 
but indicated a temporary check at least to the decline that has 
recently taken place, incident to the unsatisfactory conditions of 
the flagstone trade. 
The trap quarries in the Palisades section reported an output 
scarcely more than one-half that of previous years, in actual figures, 
$483,863 as compared with $899,414 in 1911. The decrease has 
been due to the shutting down of some of the river quarries by 
their inclusion in the new Palisades Park.
