THE MINING AND QUARRY INDUSTRY I907 7 



The clay materials reported in 1907 represented an aggregate 

 value of $12,688,868. There was a decrease of $1,266,432 from 

 the amount returned for the preceding year, due to the smaller 

 output and market values of the building materials. The com- 

 bined output of brick, tile, fireproofing and terra cotta used for 

 building purposes v^as valued at $8,909,392 as compared with 

 $11,063,433 in 1906. The number of bricks made was 1,366,842,- 

 000, of which 1,051,907,000 came from the Hudson river region. 

 The decline in the output of building materials was counter- 

 balanced to somie degree by the gain in pottery manufactures 

 which were valued at $2,240,895, against a value of $1,795,008 

 for the preceding year. Of the 61 counties of the State 43 were 

 represented among the reports received last year from the manu- 

 facturers of clay products. 



The quarries of New York contributed a value of $7,890,327, 

 against $6,504,165 in 1906, showing an increase of about 20 per 

 cent and establishing a new record for these industries. The 

 total was divided according to the various uses into : building 

 stone $2,208,545; monumental stone $162,359; curb and flag- 

 stone $1,064,193; crushed stone $2,812,998; other uses $1,642,232. 

 The output of slate, millstones and of limestone used in making 

 hydraulic cement is not included in the totals. The marble in- 

 dustry was specially active last year and the production valued 

 at $1,571,936 has probably never been exceeded in the State. 

 The stone quarries are distributed among all the counties practi- 

 cally, while they yield nearly every kind of material for building, 

 construction or ornamental purposes. 



The companies manufacturing hydraulic cement reported an 

 output of 3,245,729 barrels, with a value of $2,971,820. The 

 totals consisted of 2,108,450 barrels of Portland cement valued 

 at $2,214,090 and 1,137,279 barrels of natural rock cement 

 valued at $757,730. In the preceding year there were 4,114,939 

 barrels produced valued at $3,950,699, so that there was a loss 

 for the year pi 869,210 barrels in quantity and $978,870 in 

 value. The poor showing has been due largely to the unfavor- 

 al)le conditions that obtained in the natural cement trade which 

 has shown a steady decline for several years past. 



The salt production of the State amounted to 9,657,543 barrels, 

 as conij^arcd with 9,013,993 barrels in TO06. thus continuing the 

 progress that has for some time l)ecn a feature of the industry. 

 The value of the output was $2,44(),i78, exceeding that of the 

 previous year by $317,528. Inhere were six counties represented
