loss incurred by the decline of the latter year and placed 1912 

 almost on a par with the record year of 1907 when the total reached 

 $37,142,006. 



The materials on which these production figures are based number 

 over thirty and represent in most cases the first products of the 

 mines and quarries. They do not of course cover the whole field 

 of enterprise in this department of activity, since there are many 

 large industries based on their further elaboration or manufacture, 

 as well as others of equal importance engaged in the treatment of 

 products secured from sources outside the State. Among such 

 industries may be mentioned the manufacture of aluminum, calcium 

 carbide, carborundum, pig iron and steel, soda products, coke, and 

 many others that together greatly exceed in value of their outturn 

 those branches under present consideration. 



Among the metallic minerals found in the State, iron ore is the 

 most valuable from an industrial standpoint. The gross output 

 of this ore last year was 1,277,677 long tons. After allowance for 

 concentration, which is practised by the Adirondack mines, there 

 remained a total of 1,057,702 long tons of shipping ore which had 

 a value of $3,349,095, as compared with 952,364 long tons valued 

 at $3,184,057 for the year 191 1. There was a good advance among 

 the mines in the Clinton belt, though the magnetite ores as usual 

 constituted the greater part of the production. New developments 

 have been in progress which may lead to a material advance in 

 the industry in the near future. 



The clay-working industries contributed the largest items of the 

 totals, with an aggregate value of $11,947,497 in 1912, and 

 $9,751,659 in the preceding year. The large gain in production 

 during the year was due largely to a better demand for structural 

 materials, including common and pressed building brick, terra cotta, 

 hollow fireproofing, etc., of which the total value amounted to 

 $8,301,839, as compared with $6,473,857 in the preceding year. 

 The number of brick for building purposes made in 1912 was 

 1,205,704 thousands, against 1,078,019 thousands in 191 1, about 

 three-fourths in each year being manufactured in the Hudson 

 River district. The pottery trade also showed an improvement and 

 the returns indicated a total value for the production of $2,876,762 

 which was a new record. About 200 firms were engaged in the 

 various clay-working branches. 



The improved conditions in the building trades also brought about 

 an increased output of quarry materials, inclusive of granite, lime-
