  — 
  Educators 
  have 
  frequently 
  called 
  

   attention 
  to 
  the 
  dearth 
  of 
  books 
  and 
  articles 
  on 
  geology 
  suitable 
  

   for 
  the 
  elementary 
  student 
  and 
  general 
  reader. 
  In 
  the 
  fields 
  of 
  

   botany, 
  zoology, 
  and 
  even 
  physics 
  are 
  many 
  descriptive 
  and 
  

   explanatory 
  treatises, 
  and 
  even 
  periodicals 
  which 
  are 
  widely 
  read 
  

   by 
  the 
  non-professional 
  public, 
  but 
  most 
  publications 
  dealing 
  with 
  

   geology 
  need 
  the 
  interpretative 
  assistance 
  of 
  a 
  teacher. 
  One 
  reason 
  

   for 
  the 
  scarcity 
  of 
  suitable 
  books 
  on 
  the 
  earth 
  sciences 
  is 
  the 
  

   unusual 
  difficulty 
  of 
  preparing 
  a 
  manuscript 
  which 
  combines 
  

   authoritative 
  statements 
  with 
  simplicity 
  of 
  writing. 
  In 
  this 
  con- 
  

   nection 
  the 
  "Geology 
  of 
  Cincinnati 
  and 
  Vicinity," 
  by 
  N. 
  M. 
  Fenne- 
  

   man, 
  deserves 
  high 
  praise. 
  It 
  is 
  prepared 
  to 
  meet 
  an 
  educational 
  

   demand. 
  It 
  is 
  well 
  planned 
  and 
  clearly 
  written, 
  discards 
  contro- 
  

   versial 
  matter 
  and 
  supplements 
  the 
  statement 
  of 
  hypothesis 
  and 
  

   fact 
  by 
  description 
  and 
  illustration 
  of 
  local 
  features. 
  The 
  book 
  

   may 
  be 
  studied 
  with 
  profit 
  as 
  a 
  type 
  of 
  a 
  local 
  geologic 
  report.

  New 
  York, 
  1916 
  (McGraw-Hill 
  Book 
  Co.).— 
  There 
  

   has 
  long 
  been 
  need 
  of 
  a 
  work 
  of 
  this 
  nature, 
  which 
  could 
  be 
  

   placed 
  in 
  the 
  hands 
  of 
  students 
  who 
  are 
  taking 
  their 
  first 
  practi- 
  

   cal 
  field 
  work 
  in 
  geology. 
  The 
  excellent 
  little 
  hand-book 
  of 
  the 
  

   late 
  Dr. 
  C. 
  W. 
  Hayes 
  is 
  well 
  known 
  to 
  professional 
  geologists, 
  

   but 
  is 
  of 
  a 
  rather 
  technical 
  character, 
  written 
  more 
  especially 
  to 
  

   meet 
  the 
  demands 
  of 
  the 
  U. 
  S. 
  Geological 
  Survey, 
  and 
  less 
  

   adapted 
  to 
  the 
  use 
  of 
  beginners. 
  The 
  present 
  volume 
  gives 
  the 
  

   student 
  those 
  criteria 
  which, 
  on 
  the 
  one 
  hand, 
  will 
  enable 
  him 
  to 
  

   understand 
  what 
  he 
  sees 
  in 
  the 
  field 
  and 
  on 
  the 
  other 
  will 
  suggest 
  

   to 
  him 
  the 
  data 
  that 
  should 
  be 
  searched 
  for 
  to 
  gain 
  a 
  solution 
  of 
  

   his 
  problem. 
  The 
  scope 
  of 
  the 
  work 
  may 
  be 
  indicated 
  by 
  a 
  men- 
  

   tion 
  of 
  some 
  of 
  the 
  topics 
  treated 
  : 
  identification 
  of 
  rock 
  features, 
  

   characters 
  of 
  rock 
  particles 
  and 
  pebbles, 
  surface 
  features 
  of 
  sedi- 
  

   ments, 
  structures 
  of 
  sedimentary 
  rocks, 
  field 
  interpretation 
  of 
  

   sedimentary 
  materials, 
  features 
  of 
  igneous 
  rocks, 
  folds, 
  faults, 
  

   metamorphic 
  rocks, 
  mineral 
  deposits, 
  topographic 
  forms 
  and 
  

   expression, 
  topographic 
  maps 
  and 
  profiles, 
  geologic 
  surveying, 
  

   geologic 
  maps, 
  diagrams 
  and 
  sections, 
  geologic 
  computations, 
  

   preparation 
  of 
  reports, 
  etc. 
  The 
  work 
  is 
  clearly 
  and 
  simply 
  writ- 
  

   ten 
  with 
  avoidance 
  of 
  details 
  and 
  discussions, 
  the 
  writer 
  having 
  

   evidently 
  his 
  student 
  audience 
  in 
  mind. 
  

  

  It 
  is 
  published 
  in 
  a 
  form 
  and 
  size 
  convenient 
  for 
  transporting 
  ; 
  

   it 
  is 
  well 
  printed 
  and 
  very 
  fully 
  illustrated 
  by 
  half-tones, 
  sections 
  

   and 
  diagrams. 
  The 
  only 
  criticism 
  which 
  could 
  be 
  passed 
  on 
  its 
  

   make-up, 
  is 
  that 
  if 
  a 
  greater 
  reduction 
  in 
  the 
  reproduction 
  of 
  the 
  

   drawings 
  had 
  been 
  made, 
  the 
  illustrations 
  would 
  have 
  been 
  as 
  

   serviceable 
  and 
  had 
  a 
  neater 
  effect 
  ; 
  compare 
  figs. 
  49 
  and 
  281 
  for 
  

   example. 
  

  

  The 
  book 
  is 
  commended 
  for 
  examination 
  to 
  all 
  teachers 
  who 
  

   have 
  courses 
  in 
  field 
  geology.
