MINING. New York has no coal mines, and is in this respect in marked contrast with the sister Commonwealth of Pennsylvania. The State ranks high in the stone-quarrying industry. All the more important varieties of stone, as well as industrial Attys. are worked. The out put of limestone in 1900 was valued at $1,i30, 102. the largest for any year in the decade 1890 1900. The sandstone for the same year (nearly two-thirds being bluestone) was valued at $1,467,490—also the largest value attained from 1890 to 1900. The annual production of granite and of marble each ranges in value from ?bout $200,000 to $500,000. Slate is of less impor tance. New York produces over half of the total output of rock cement for the country, the value for 1900 being $2.045,451. Portland cement is also made. The value of the clay products for 1900 was $8,073.769—a little less than in 1890— of which over one-sixth represented pottery, and the remainder brick and tile. New York is the
largest salt-producing State, the value of the pro duct being over one-third that for the entire country. Prior to 1893 New Yo•k was exceeded by Michigan in the salt output, but it has regu larly held first rank since that year. Since 1898 the annual value has been more than $2, 000.0110. The yield of the different kinds of iron ore in 1900 was: red hematite. 44,407 long tons; brown hematite, 44,891 ; magnetite, 345.714: and carbonate. 6413 long tons, the value of the en tire product being $1.103.817. Petrolemn and natural gas arc obtained in the western part of the State. The value of the natural gas yield was greatest in 1390—$552.000. The highest sub sequent fi7ure was that fur 1900—$363.307. Only one State, Wisconsin, exceeds New York in the value of its mineral waters, the total receipts being $929,038, from •11 springs reporting in 1900.
