  the 
  spot 
  wliere 
  the 
  old 
  mine 
  had 
  caved 
  in 
  and 
  was 
  abandoned. 
  It 
  

   was 
  subsequently 
  connected 
  with 
  the 
  main 
  drift 
  by 
  an 
  uplift 
  along 
  

   the 
  seau], 
  leaving 
  a 
  supporting 
  pillar 
  which 
  gives 
  an 
  excellent 
  

   section 
  of 
  the 
  talc 
  seam. 
  

  

  Pumping 
  is 
  necessary, 
  and 
  when 
  a 
  mine 
  is 
  abandoned 
  it 
  soon 
  fills 
  

   with 
  water 
  to 
  within 
  a 
  few 
  feet 
  of 
  the 
  surface. 
  

  

  Mine 
  No. 
  5, 
  of 
  the 
  International 
  pulp 
  co. 
  This 
  mine 
  is 
  

   located 
  on 
  the 
  east 
  side 
  of 
  the 
  same 
  hillock 
  as 
  mine 
  No. 
  3, 
  

   and 
  is 
  about 
  500 
  yards 
  distant 
  from 
  it. 
  It 
  is 
  not 
  quite 
  so 
  deep 
  as 
  

   its 
  neighbor 
  and 
  is 
  operated 
  on 
  two 
  levels. 
  Tlie 
  skip-way 
  is 
  con- 
  

   siderably 
  steeper, 
  and 
  the 
  talc 
  on 
  coming 
  from 
  the 
  mine 
  in 
  the 
  

   skips 
  is 
  automatically 
  dumped 
  into 
  another 
  car 
  and 
  run 
  down 
  to 
  

   the 
  railroad 
  by 
  gravity, 
  the 
  empty 
  car 
  being 
  hauled 
  back 
  by 
  a 
  

   cable. 
  Plate 
  2, 
  sliows 
  the 
  entrance 
  to 
  mine 
  No. 
  5, 
  the 
  waste 
  dump, 
  

   a 
  loaded 
  car 
  on 
  the 
  skip-way 
  and 
  the 
  track 
  connecting 
  with 
  the 
  rail- 
  

   road. 
  The 
  rails 
  of 
  the 
  skip 
  way 
  are 
  bent 
  to 
  a 
  horizontal 
  position 
  as 
  

   they 
  enter 
  the 
  shed. 
  The 
  front 
  wheels 
  of 
  the 
  car 
  follow 
  these 
  rails, 
  

   but 
  the 
  rollers 
  projecting 
  beyond 
  the 
  rear 
  wheels 
  are 
  caught 
  by 
  sup- 
  

   plementary 
  rails 
  and 
  the 
  rear 
  of 
  the 
  car 
  is 
  thus 
  carried 
  upward, 
  

   dumping 
  the 
  contents 
  into 
  the 
  third 
  car 
  on 
  the 
  track 
  below. 
  

  

  A 
  slight 
  difference 
  in 
  texture 
  can 
  be 
  noticed 
  between 
  the 
  best 
  

   grades 
  of 
  talc 
  from 
  mines 
  Nos. 
  3 
  and 
  5, 
  in 
  fact 
  this 
  statement 
  is 
  

   true 
  of 
  almost 
  all 
  of 
  the 
  mines.

  Varieties 
  and 
  occurrence 
  of 
  the 
  talc. 
  Two 
  grades 
  of 
  talc 
  are 
  

   mined. 
  (1) 
  "First 
  quality 
  fiber," 
  This 
  is 
  a 
  compact 
  rock, 
  some- 
  

   what 
  variable 
  in 
  appearance. 
  Its 
  two 
  chief 
  types 
  are 
  characterized 
  

   as 
  follows 
  : 
  (a) 
  distinctly 
  fibrous 
  in 
  structure, 
  with 
  clusters 
  of 
  fibers 
  

   ramifying 
  in 
  all 
  directions, 
  and 
  usually 
  of 
  a 
  grayish 
  tint 
  ; 
  (b) 
  lack- 
  

   ing 
  somewhat 
  in 
  the 
  fibrous 
  appearance, 
  as 
  the 
  fibres 
  tend 
  to 
  run 
  in 
  

   one 
  direction, 
  and 
  usually 
  of 
  a 
  light 
  sea-green 
  tint. 
  Both 
  types 
  

   when 
  crushed 
  form 
  a 
  snow 
  white 
  pulp. 
  (2) 
  " 
  Second 
  quality 
  fiber" 
  

   may 
  be 
  either 
  (a) 
  "gritty", 
  when 
  an 
  otherwise 
  first 
  quality 
  material 
  

   contains 
  some 
  harder 
  impurity, 
  which 
  is 
  usually 
  tremolite 
  or 
  some 
  

   other 
  member 
  of 
  the 
  amphibole 
  group 
  ; 
  or 
  (b) 
  " 
  scaly 
  " 
  when 
  it 
  

   does 
  not 
  possess 
  a 
  fibrous 
  structure 
  and 
  consequently 
  tough 
  charac-
