were the emery mines in Westchester county which reported an 

 output of 3895 short tons against 763 short tons in 1914. The 

 Adirondack garnet mines contributed 3900 short tons of that 

 mineral as compared with 4026 tons in 19 14. The talc mines were 

 adversely affected by market conditions which are largely governed 

 by the state of the paper trade. They contributed a total of 65,914 

 short tons, or a little less than in the preceding year.
