  Winter 
  mine. 
  The 
  mine 
  is 
  situated 
  1 
  mile 
  northeast 
  of 
  Clinton- 
  

   ville 
  near 
  Lilly 
  pond. 
  There 
  are 
  three 
  or 
  more 
  small 
  bands 
  of 
  ore 
  

   outcropping 
  in 
  a 
  course 
  somewhat 
  west 
  of 
  north 
  and 
  standing 
  ver- 
  

   tically 
  or 
  nearly 
  so. 
  The 
  main 
  band 
  is 
  about 
  10 
  feet 
  wide. 
  It 
  has 
  

   been 
  worked 
  by 
  open-cast 
  methods 
  on 
  the 
  south 
  end, 
  while 
  on 
  the 
  

   north 
  it 
  has 
  been 
  followed 
  by 
  a 
  slope 
  which 
  extends 
  into 
  the 
  hill 
  

   for 
  about 
  100 
  feet 
  where 
  it 
  connects 
  with 
  an 
  adit 
  driven 
  along 
  the 
  

   course 
  of 
  a 
  diabase 
  dike 
  from 
  the 
  east. 
  Beyond 
  the 
  entrance 
  of 
  the 
  

   adit 
  the 
  workings 
  are 
  no 
  longer 
  accessible, 
  but 
  apparently 
  the 
  ore 
  

   body 
  flattens 
  out 
  to 
  nearly 
  horizontal. 
  The 
  relations, 
  however, 
  are 
  

   obscured 
  by 
  the 
  numerous 
  dikes 
  which 
  intersect 
  the 
  workings. 
  

   Three 
  of 
  these 
  are 
  found 
  crossing 
  the 
  main 
  slope, 
  the 
  largest 
  lying 
  

   along 
  the 
  axis 
  of 
  the 
  adit 
  already 
  mentioned. 
  The 
  ore 
  contains 
  

   much 
  white 
  quartz; 
  an 
  incomplete 
  analysis 
  is 
  here 
  given.

  Mace 
  mine. 
  This 
  is 
  based 
  on 
  a 
  small 
  deposit 
  situated 
  north 
  of 
  

   the 
  Winter 
  mine. 
  It 
  has 
  been 
  worked 
  principally 
  as 
  an 
  open 
  pit, 
  

   which 
  has 
  a 
  length 
  of 
  about 
  500 
  feet. 
  The 
  width 
  ranges 
  from 
  3 
  to 
  

   10 
  feet. 
  The 
  ore 
  is 
  lean 
  and, 
  except 
  for 
  its 
  larger 
  proportion 
  of 
  

   magnetite, 
  resembles 
  the 
  wall 
  rock. 
  The 
  latter 
  is 
  a 
  hornblende 
  

   gneiss 
  of 
  granitic 
  appearance. 
  

  

  LYON 
  MOUNTAIN 
  MINES 
  

  

  The 
  Lyon 
  Mountain 
  or 
  Chateaugay 
  mines 
  are 
  in 
  the 
  town 
  of 
  

   Dannemora, 
  near 
  the 
  western 
  border 
  of 
  Clinton 
  county. 
  The 
  cen- 
  

   tral 
  point 
  of 
  the 
  group 
  is 
  Lyon 
  Mountain, 
  a 
  settlement 
  limited 
  

   almost 
  entirely 
  to 
  mine 
  employees 
  and 
  their 
  families, 
  situated 
  on 
  the 
  

   Lake 
  Placid 
  branch 
  of 
  the 
  Delaware 
  & 
  Hudson 
  Railroad, 
  37 
  miles 
  

   from 
  Plattsburg. 
  

  

  In 
  size 
  the 
  mines 
  are 
  among 
  the 
  largest 
  in 
  the 
  State. 
  They 
  are 
  

   widely 
  reputed 
  also 
  for 
  the 
  high 
  quality 
  of 
  their 
  product.
