  raent 
  at 
  this 
  time 
  would 
  be 
  a 
  loss 
  of 
  all 
  that 
  had 
  been 
  

   expended, 
  and 
  it 
  was 
  too 
  important 
  a 
  matter 
  to 
  risk 
  any 
  

   chance 
  of 
  losing 
  the 
  continuity 
  of 
  the 
  record 
  which 
  had 
  

   been 
  so 
  far 
  kept, 
  both 
  by 
  written 
  observations 
  and 
  by 
  

   the 
  collection 
  of 
  abundant 
  specimens. 
  This 
  money, 
  which 
  had 
  

   been 
  allotted 
  for 
  palaeontology, 
  amounting 
  to 
  $450, 
  was 
  again 
  

   appropriated 
  to 
  the 
  continuation 
  of 
  the 
  work 
  on 
  the 
  shaft 
  with 
  

   the 
  distinct 
  understanding 
  that 
  the 
  amount 
  would 
  be 
  refunded 
  

   at 
  a 
  future 
  period 
  for 
  use 
  in 
  palseontological 
  work. 
  

  

  By 
  the 
  law 
  passed 
  in 
  1892, 
  chapter 
  170, 
  means 
  were 
  provided 
  

   for 
  continuing 
  work 
  upon 
  the 
  Livonia 
  salt 
  shaft, 
  and 
  written 
  

   records 
  and 
  collections 
  have 
  marked 
  the 
  progress 
  of 
  the 
  work 
  

   from 
  the 
  time 
  of 
  beginning 
  (at 
  the 
  depth 
  of 
  380 
  feet) 
  to 
  the 
  

   depth 
  of 
  over 
  1,432 
  feet. 
  

  

  At 
  the 
  time 
  Mr. 
  Luther 
  went 
  upon 
  the 
  ground, 
  in 
  May, 
  1891, 
  

   the 
  rock 
  had 
  been 
  penetrated 
  to 
  the 
  depth 
  of 
  380 
  feet, 
  which 
  

   would 
  give 
  a 
  little 
  over 
  300 
  feet 
  in 
  the 
  shales 
  of 
  the 
  Genesee 
  

   and 
  Hamilton 
  groups, 
  of 
  which 
  no 
  accurate 
  records 
  had 
  been 
  

   kept, 
  and 
  our 
  means 
  of 
  knowing 
  the 
  character 
  of 
  the 
  rocks 
  passed 
  

   through 
  in 
  this 
  interval 
  could 
  only 
  be 
  obtained 
  from 
  the 
  materia! 
  

   thrown 
  out 
  upon 
  the 
  dump, 
  which 
  will, 
  in 
  some 
  measure, 
  supply 
  

   the 
  deficiency. 
  

  

  The 
  following 
  summary 
  will 
  give 
  all 
  the 
  necessary 
  general
