  As 
  a 
  result 
  of 
  twenty-five 
  

   years 
  of 
  local 
  endeavor, 
  Professor 
  Miller 
  of 
  the 
  University 
  of 
  

   Kentucky 
  here 
  describes 
  the 
  essential 
  geology 
  of 
  his 
  state. 
  

   Seven 
  chapters 
  are 
  devoted 
  to 
  a 
  more 
  or 
  less 
  detailed 
  description 
  

   of 
  the 
  stratigraphy, 
  two 
  to 
  the 
  physiography, 
  two 
  to 
  the 
  geologic 
  

   structure, 
  seven 
  to 
  the 
  economic 
  products, 
  and 
  the 
  last 
  part 
  gives 
  

   the 
  literature 
  referring 
  to 
  the 
  whole 
  subject. 
  The 
  geographic 
  

   distribution 
  of 
  most 
  of 
  the 
  formations 
  is 
  illustrated 
  on 
  maps, 
  

   one 
  for 
  each 
  period, 
  and 
  there 
  are 
  many 
  plates 
  picturing 
  the 
  

   more 
  typical 
  fossils 
  of 
  the 
  formations 
  beneath 
  the 
  Coal 
  Measures. 
  

   This 
  book 
  will 
  do 
  much 
  good 
  in 
  spreading 
  a 
  correct 
  knowledge 
  

   of 
  geology 
  throughout 
  Kentucky, 
  and 
  at 
  the 
  same 
  time 
  serving 
  as 
  

   a 
  reference 
  work 
  for 
  American 
  geologists. 
  We 
  congratulate 
  the 
  

   author 
  upon 
  the 
  successful 
  conclusion 
  of 
  this 
  his 
  favorite 
  study 
  

   and 
  his 
  long 
  labor 
  of 
  love 
  for 
  his 
  fellow 
  citizens.

  This 
  study 
  

   in 
  regional 
  geography 
  of 
  an 
  area 
  as 
  large 
  as 
  Ireland 
  is 
  written 
  

   by 
  a 
  native 
  of 
  the 
  region, 
  who 
  is 
  deeply 
  interested 
  in 
  its 
  welfare 
  

   though 
  he 
  does 
  not 
  now 
  live 
  there. 
  It 
  is 
  a 
  collection 
  of 
  facts 
  

   relating 
  to 
  the 
  environment, 
  such 
  as 
  the 
  rock 
  formations, 
  erosion 
  

   cycles, 
  climate, 
  and 
  material 
  resources; 
  to 
  the 
  settlement 
  and 
  

   development 
  of 
  the 
  area 
  by 
  the 
  French, 
  Americans, 
  and 
  Ger- 
  

   mans; 
  and 
  to 
  the 
  recent 
  economic 
  conditions. 
  He 
  says 
  in 
  con- 
  

   clusion 
  : 
  

  

  "By 
  developing 
  along 
  the 
  lines 
  sketched 
  [in 
  this 
  book] 
  the 
  

   Ozark 
  Highland 
  will 
  offer 
  homes 
  to 
  a 
  much 
  larger 
  number 
  of 
  

   people 
  under 
  much 
  better 
  conditions 
  than 
  at 
  present. 
  Few 
  of 
  

   them 
  will 
  accumulate 
  large 
  wealth, 
  but, 
  engaged 
  in 
  useful 
  pur- 
  

   suits, 
  they 
  will 
  be 
  strangers 
  to 
  poverty, 
  and 
  they 
  may 
  participate 
  

   equitably 
  in 
  the 
  progress 
  of 
  the 
  state. 
  By 
  thus 
  becoming 
  the 
  

   seat 
  of 
  an 
  enlightened 
  and 
  contented 
  population, 
  preserving 
  still 
  

   the 
  democratic 
  spirit 
  which 
  it 
  now 
  possesses, 
  this 
  region 
  in 
  the 
  

   future 
  may 
  make 
  its 
  appropriate 
  and 
  sufficient 
  contribution 
  to 
  

   our 
  national 
  life.

  The 
  attention 
  of 
  

   geologists 
  and 
  stratigraphers 
  is 
  called 
  to 
  this 
  valuable 
  manual 
  

   setting 
  forth 
  clearly 
  the 
  geology 
  of 
  India 
  as 
  brought 
  up 
  to 
  date. 
  

   The 
  book 
  is 
  intended 
  for 
  college 
  students, 
  but 
  is 
  in 
  reality 
  one 
  

   for 
  geologists. 
  It 
  deals 
  with 
  the 
  physical 
  features, 
  the 
  strati- 
  

   graphy 
  and 
  historical 
  geology 
  from 
  the 
  Archean 
  to 
  the 
  Pleisto- 
  

   cene, 
  the 
  Deccan 
  trap, 
  and 
  the 
  economic 
  geology 
  of 
  India.
