  This 
  book 
  

   gives 
  a 
  review 
  of 
  the 
  oil 
  and 
  gas 
  resources 
  of 
  Kentucky. 
  In 
  

   1910, 
  the 
  production 
  had 
  fallen 
  to 
  468,000 
  barrels, 
  but 
  in 
  1919 
  it 
  

   is 
  thought 
  there 
  will 
  be 
  about 
  7,500,000 
  barrels 
  valued 
  at 
  $19,- 
  

   500,000. 
  The 
  drilling 
  records 
  of 
  752 
  wells 
  are 
  presented 
  (pages 
  

   178-544) 
  , 
  along 
  with 
  data 
  on 
  oil 
  production, 
  a 
  history 
  of 
  oil 
  and 
  

   gas 
  development 
  in 
  the 
  state 
  since 
  1819, 
  etc. 
  Many 
  illustrations 
  

   and 
  maps 
  accompany 
  the 
  report.

  — 
  This 
  carefully 
  wrought 
  out 
  work 
  by 
  Doctor 
  

   O'Connell 
  treats 
  of 
  800 
  specimens 
  of 
  well 
  preserved 
  siliceous 
  

   sponges 
  found 
  in 
  the 
  Cretaceous 
  of 
  Germany, 
  and 
  chiefly 
  around 
  

   Hannover. 
  There 
  are 
  116 
  genera 
  represented 
  by 
  222 
  species, 
  

   nearly 
  all 
  of 
  which 
  have 
  their 
  structure 
  discussed 
  in 
  detail. 
  

   This 
  remarkable 
  European 
  wealth 
  contrasts 
  strikingly 
  with 
  the 
  

   almost 
  total 
  absence 
  in 
  America 
  of 
  fossil 
  Cretaceous 
  sponges. 
  

   The 
  author 
  also 
  deals 
  with 
  the 
  classification 
  of 
  sponges, 
  and 
  

   makes 
  the 
  work 
  of 
  Zittel-Broili 
  and 
  Schrammen 
  along 
  this 
  line 
  

   available 
  to 
  English-speaking 
  students. 
  The 
  most 
  valuable 
  part 
  

   of 
  the 
  work, 
  because 
  of 
  its 
  wide 
  application, 
  is 
  a 
  chapter 
  sum- 
  

   ming 
  up 
  the 
  present 
  knowledge 
  of 
  the 
  stratigraphy 
  of 
  the 
  Cre- 
  

   taceous 
  of 
  Europe. 
  The 
  author 
  has 
  gone 
  to 
  the 
  original 
  sources 
  

   and 
  brings 
  together 
  a 
  clear-cut 
  description 
  of 
  the 
  successive 
  

   formations 
  of 
  England 
  and 
  western 
  Europe 
  that 
  have 
  the 
  won- 
  

   derful 
  array 
  of 
  Silicispongias.

  — 
  Dr. 
  S. 
  Passarge, 
  known 
  for 
  his 
  

   explorations 
  of 
  South 
  Africa 
  fifteen 
  years 
  ago 
  and 
  later 
  as 
  pro- 
  

   fessor 
  of 
  geography 
  at 
  the 
  University 
  of 
  Hamburg, 
  has 
  prepared 
  

   this 
  volume 
  as 
  an 
  empirical 
  introduction 
  to 
  the 
  observational 
  

   study 
  of 
  landscapes. 
  His 
  plan 
  is 
  peculiar 
  in 
  excluding, 
  except 
  

   for 
  unintentional 
  explanatory 
  allusions, 
  all 
  that 
  has 
  been 
  learned 
  

   in 
  the 
  last 
  century 
  regarding 
  the 
  origin 
  of 
  land 
  forms, 
  on 
  the 
  

   ground 
  that 
  unprejudiced 
  observation 
  should 
  precede 
  genetic 
  or 
  

   explanatory 
  description. 
  The 
  number 
  of 
  terms 
  that 
  he 
  thus 
  

   defines 
  is 
  large 
  ; 
  and 
  his 
  plan 
  for 
  the 
  empirical 
  analysis 
  of 
  land- 
  

   scapes 
  is 
  excellent. 
  His 
  volume 
  must, 
  therefore, 
  prove 
  useful 
  to 
  

   travelers 
  who 
  have 
  no 
  knowledge 
  of 
  modern 
  physiography, 
  yet 
  

   who 
  wish 
  to 
  make 
  some 
  record 
  of 
  what 
  they 
  see. 
  But 
  the 
  book 
  

   is 
  also 
  intended 
  as 
  a 
  text 
  for 
  university 
  students 
  ; 
  and 
  for 
  them
