  harie 
  gritsappear 
  overlaid 
  by 
  the 
  Cornif 
  erous 
  limestone, 
  and 
  these, 
  

   about 
  four 
  miles 
  west 
  of 
  Saugerties 
  at 
  Quarry 
  ville, 
  by 
  the 
  Ham- 
  

   ilton 
  group. 
  

  

  It 
  will 
  thus 
  be 
  seen'that 
  in 
  Ulster 
  county 
  the 
  present 
  available 
  

   localities 
  for 
  cement 
  rock 
  are 
  quite 
  preempted. 
  Beginning 
  

   near 
  East 
  Kingston 
  the 
  cement 
  rock 
  shows 
  on 
  the 
  east 
  face 
  of 
  a 
  

   steep 
  escarpment. 
  This 
  outcrop 
  can 
  be 
  almost 
  continuously 
  

   traced 
  to 
  the 
  Newark 
  Lime 
  and 
  Cement 
  Company's 
  mines. 
  From 
  

   this 
  point 
  south 
  the 
  city 
  of 
  Kondout 
  covers 
  the 
  ground, 
  but 
  at 
  

   Wilbur 
  the 
  rock 
  appears 
  and 
  is 
  mined 
  at 
  numerous 
  places 
  along 
  

   the 
  river 
  to 
  Eosendale. 
  In 
  this 
  region 
  the 
  general 
  dip 
  is 
  to 
  the 
  

   northwest. 
  Beginning 
  at 
  Eosendale 
  and 
  following 
  the 
  line 
  of 
  

   the 
  Walkill 
  Valley 
  railroad 
  toward 
  Kingston 
  cement 
  rock 
  is 
  

   found 
  on 
  either 
  side 
  of 
  the 
  road. 
  On 
  the 
  right, 
  going 
  to 
  King- 
  

   ston, 
  the 
  dip 
  is 
  generally 
  steeply 
  southeast, 
  while 
  on 
  the 
  left, 
  

   going 
  to 
  Kingston, 
  the 
  dip, 
  at 
  Binnewater, 
  is 
  to 
  the 
  northwest. 
  

   (See 
  cut 
  of 
  Newark 
  and 
  Eosendale 
  mines 
  ; 
  also 
  Lawrenceville 
  

   Cement 
  Company's 
  mines.) 
  

  

  From 
  this 
  statement 
  it 
  will 
  appear 
  that 
  in 
  the 
  tongue 
  of 
  land 
  

   lying 
  between 
  the 
  river 
  and 
  the 
  railroad 
  the 
  cement 
  beds 
  lie 
  in 
  a 
  

   synclinal 
  trough, 
  and 
  that 
  the 
  railroad 
  runs 
  on 
  the 
  broken 
  and 
  

   eroded 
  anticlinal 
  which 
  formerly 
  joined 
  the 
  two 
  beds. 
  From 
  

   Eosendale 
  to 
  High 
  Falls 
  there 
  are 
  numerous 
  cement 
  mines, 
  all 
  on 
  

   the 
  northwest 
  side 
  of 
  Eondout 
  creek. 
  At 
  High 
  Falls, 
  however, 
  

   the 
  cement 
  beds 
  lie 
  on 
  the 
  southeast 
  bank. 
  The 
  probability 
  that 
  

   the 
  cement 
  beds, 
  referred 
  to 
  as 
  lying 
  between 
  the 
  "Walkill 
  and 
  

   the 
  railroad, 
  lie 
  in 
  a 
  synclinal 
  trough 
  is 
  intensified 
  by 
  the 
  fact 
  

   that 
  the 
  Cauda-galli 
  grits 
  occur 
  in 
  heavy 
  beds 
  in 
  Eondout 
  west 
  

   of 
  the 
  cement 
  mines, 
  and 
  that 
  the 
  Corniferous 
  limestones 
  overlying 
  

   them 
  occur 
  farther 
  west 
  and 
  a 
  little 
  east 
  of 
  the 
  West 
  Shore 
  rail- 
  

   road 
  station 
  at 
  Kingston. 
  Although 
  the 
  cement 
  rock 
  thus 
  lies 
  

   in 
  a 
  synclinal 
  trough, 
  it 
  is 
  by 
  no 
  means 
  a 
  simple 
  fold. 
  The 
  rocks 
  

   are 
  subjected 
  to 
  the 
  most 
  violent 
  crushing 
  and 
  folding. 
  In 
  the 
  

   Newark 
  company's 
  quarry 
  at 
  Eondout 
  the 
  outcrop 
  is 
  nearly 
  ver- 
  

   tical. 
  This 
  is 
  succeeded, 
  in 
  the 
  mines, 
  by 
  a 
  flattening 
  and 
  then 
  by 
  

   a 
  steep 
  dip 
  to 
  the 
  northwest. 
  Abrupt 
  folds 
  are 
  also 
  to 
  be 
  observed 
  

   in 
  the 
  mines 
  between 
  Binnewater 
  and 
  Whiteport. 
  It 
  is 
  thus 
  

   probable 
  that 
  the 
  cement 
  rock 
  even 
  in 
  this 
  tongue 
  of 
  land 
  is 
  

   almost 
  inexhaustible. 
  The 
  only 
  question 
  is, 
  can 
  it 
  be 
  won 
  with
