﻿THE 
  MINING 
  AND 
  QUARRY 
  INDUSTRY

  probably 
  the 
  largest 
  on 
  record, 
  and 
  was 
  considerably 
  in 
  excess 
  

   of 
  that 
  reported 
  for 
  any 
  recent 
  year. 
  A 
  total 
  of 
  about 
  750,000 
  

   tons 
  was 
  hoisted 
  from 
  the 
  mines 
  of 
  Witherbee, 
  Sherman 
  & 
  Co., 
  

   and 
  the 
  Port 
  Henry 
  Iron 
  Ore 
  Co. 
  The 
  so 
  called 
  Old 
  Bed 
  mine 
  

   group 
  which 
  includes 
  the 
  " 
  21," 
  Joker 
  and 
  Bonanza 
  workings 
  

   furnished 
  the 
  greater 
  part 
  of 
  the 
  output, 
  but 
  the 
  Harmony 
  shafts 
  

   of 
  Witherbee, 
  Sherman 
  & 
  Co. 
  contributed 
  a 
  considerable 
  share 
  

   The 
  expansion 
  of 
  mining 
  has 
  been 
  made 
  possible 
  by 
  the 
  addition 
  

   of 
  the 
  power 
  facilities 
  from 
  the 
  new 
  electric 
  station 
  on 
  the 
  lake 
  

   side 
  at 
  Port 
  Henry. 
  This 
  plant 
  supplying 
  800 
  kw. 
  was 
  placed 
  

   in 
  operation 
  during 
  the 
  past 
  year. 
  

  

  The 
  Port 
  Henry 
  Iron 
  Ore 
  Co., 
  has 
  been 
  engaged 
  in 
  sinking 
  its 
  

   new 
  shaft 
  on 
  the 
  " 
  21 
  " 
  property 
  east 
  of 
  the 
  Bonanza 
  shaft. 
  It 
  

   will 
  have 
  a 
  vertical 
  depth 
  of 
  500 
  feet, 
  with 
  crosscuts 
  at 
  intervals 
  

   of 
  80 
  feet 
  extending 
  into 
  the 
  ore 
  body. 
  It 
  is 
  divided 
  into 
  three 
  

   compartments 
  of 
  which 
  two 
  are 
  for 
  hoisting 
  and 
  will 
  have 
  a 
  

   capacity 
  of 
  1500 
  tons 
  a 
  day. 
  This 
  will 
  more 
  than 
  double 
  the 
  

   former 
  output 
  of 
  the 
  mine, 
  bringing 
  the 
  total 
  hoisting 
  capacity 
  

   of 
  the 
  two 
  companies 
  up 
  to 
  fully 
  1,000^000 
  tons 
  annually. 
  

  

  Mining 
  is 
  to 
  be 
  resumed 
  on 
  the 
  Barton 
  hill 
  group 
  which 
  has 
  

   lain 
  idle 
  for 
  several 
  years. 
  The 
  group 
  comprises 
  a 
  number 
  of 
  

   openings 
  made 
  at 
  intervals 
  along 
  a 
  practically 
  continuous 
  bed 
  

   that 
  lies 
  to 
  the 
  west 
  of 
  the 
  Old 
  Bed 
  mines 
  and 
  extends 
  3500 
  feet 
  

   in 
  a 
  northerly 
  direction 
  over 
  the 
  shoulder 
  of 
  Barton 
  hill. 
  An 
  adit 
  

   starting 
  from 
  the 
  Arch 
  pit 
  near 
  the 
  middle 
  of 
  the 
  bed 
  is 
  under 
  

   construction 
  and 
  will 
  give 
  an 
  outlet 
  to 
  the 
  surface 
  for 
  the 
  ore 
  

   in 
  the 
  northern 
  section 
  where 
  recent 
  exploration 
  has 
  disclosed 
  

   the 
  existence 
  of 
  bodies 
  hitherto 
  unworked. 
  

  

  Benson 
  mines. 
  This 
  property 
  belonging 
  to 
  the 
  Magnetic 
  

   Iron 
  Ore 
  Co. 
  has 
  been 
  taken 
  over 
  by 
  the 
  Benson 
  Mines 
  Co., 
  and 
  

   was 
  again 
  placed 
  in 
  operation 
  in 
  the 
  fall 
  of 
  1907 
  after 
  making 
  

   improvements 
  in 
  the 
  mining 
  and 
  milling 
  equipment. 
  Altogether 
  

   about 
  $150,000 
  was 
  expended 
  in 
  bringing 
  the 
  installation 
  up 
  to 
  

   date. 
  

  

  The 
  deposits 
  are 
  low 
  grade, 
  averaging 
  about 
  35 
  per 
  cent 
  iron, 
  

   but 
  they 
  rank 
  among 
  the 
  largest 
  in 
  the 
  Adirondacks. 
  In 
  their 
  

   general 
  character 
  they 
  resemble 
  those 
  at 
  Lyon 
  Mountain; 
  they 
  

   consist 
  of 
  bands 
  of 
  the 
  country 
  gneiss 
  carrying 
  magnetite 
  in 
  

   disseminated 
  grains 
  more 
  or 
  less 
  evenly 
  distributed 
  through 
  the 
  

   mass 
  of 
  the 
  rock. 
  A 
  width 
  of 
  over 
  200 
  feet 
  is 
  shown 
  in 
  the 
  old 
  

   workings, 
  while 
  the 
  ore 
  can 
  be 
  traced 
  by 
  outcrops 
  of 
  magnetic 
  

   attraction 
  for 
  a 
  distance 
  of 
  over 
  2 
  miles 
  along 
  the 
  strike.
