O NEW YORK STATE MUSEUM 



as compared with the value of $34,742,287 for the output in the 

 preceding year, but it falls considerably short of the high mark 

 reached in 1907 when a production of over $37,000,000 was re- 

 ported. 



The figures as given are based on some thirty different materials 

 in their crude or first marketable forms, but can not be considered 

 as representing the full importance which the mineral industries 

 share in the activities of the State. They are serviceable, however, 

 as standards for comparing the conditions in these fundamental 

 branches so closely allied with many other businesses of chemical, 

 metallurgical or engineering nature. The manufacture of pig iron 

 by local furnaces is alone nearly equal to the totals given for the 

 entire output of the mines and quarries. 



One of the few mineral products that showed a decided gain 

 during the year was iron ore, of which the gross output amounted 

 to 1,517,880 long tons. This is probably the largest cjuantity that has 

 ever been hoisted from the New York mines. After allowance for 

 concentration there remained suitable for furnace use a total of 

 1,159,067 tons of ore which had a value of $3,906,478. The cor- 

 responding figures for 1909 were 991,008 tons valued at $3,179,358. 

 The Adirondack region furnished, as usual, the greater part of the 

 product, but the mines in the Clinton belt of central and western 

 New York were more active than for some time. Altogether there 

 were thirteen companies who reported a production, as compared 

 with twelve in 1909 and ten in 1908. 



The clay-working industries contributed an important share of 

 the total value with an aggregate of $11,518,982 for the various 

 materials which were manufactured. In comparison with the record 

 for 1909 this showed a slight decrease, for which the dull season in 

 the building trades was mainly responsible. The output of clay struc- 

 tural materials, such as brick, terra cotta, tile and fire proofing, was 

 valued at $8,067,098 against $9,342,015 in 1909, a decline of nearly 

 15 per cent. The number of brick for building purposes made last 

 year was 1,404,345 thousands against 1,518,023 thousands in 1909, 

 of which the plants in the Hudson river region contributed about 

 three-fourths. On the other hand the value of the pottery manu- 

 facturers showed a good gain with a total of $2,136,518 against 

 $1,827,193 in the preceding year. The number of plants engaged in 

 the different branches of clay manufacturing was 223, or nine less 

 than 1909.
