﻿INTRODUCTION.

  calcareous 
  fertilizers 
  are 
  as 
  abundant, 
  as 
  varied 
  in 
  

   character, 
  and 
  excellent 
  in 
  quality, 
  as 
  any 
  other 
  State 
  

   can 
  boast. 
  

  

  To 
  ascertain 
  and 
  point 
  out 
  the 
  chief 
  deposits 
  of 
  these 
  

   marls, 
  and 
  to 
  determine 
  their 
  relative 
  value 
  and 
  chemi- 
  

   cal 
  constituents, 
  becomes 
  now 
  an 
  object 
  of 
  much 
  im- 
  

   portance. 
  Exact 
  analyses 
  of 
  the 
  different 
  varieties, 
  

   characterizing 
  them 
  by 
  the 
  prevailing 
  fossils, 
  when 
  such 
  

   exist, 
  so 
  as 
  at 
  once 
  to 
  be 
  identified 
  by 
  the 
  planter, 
  should 
  

   be 
  made; 
  numerous 
  experiments 
  in 
  their 
  application 
  

   should 
  be 
  encouraged; 
  and 
  the 
  effects 
  upon 
  the 
  growth 
  

   of 
  our 
  different 
  agricultural 
  productions 
  should 
  be 
  dili- 
  

   gently 
  observed, 
  and 
  accurately 
  detailed. 
  

  

  The 
  attention 
  of 
  planters 
  has 
  been 
  pointed 
  to 
  these 
  

   fertilizers 
  on 
  all 
  suitable 
  occasions, 
  and 
  in 
  a 
  few 
  instances 
  

   experiments 
  on 
  a 
  limited 
  scale 
  have 
  been 
  commenced, 
  

   the 
  result 
  of 
  which 
  cannot 
  of 
  course 
  yet 
  be 
  given. 
  

   Specimens 
  have 
  also 
  been 
  collected, 
  with 
  their 
  associated 
  

   and 
  characteristic 
  fossils, 
  and 
  have 
  been 
  deposited 
  for 
  

   general 
  inspection, 
  in 
  the 
  State 
  Cabinet 
  at 
  the 
  Capitol, 
  

   and 
  in 
  the 
  Cabinet 
  of 
  the 
  University 
  at 
  Oxford. 
  

  

  Analyses 
  of 
  many 
  varieties 
  of 
  our 
  marls 
  and 
  soils 
  

   should 
  have 
  been 
  given 
  in 
  this 
  Report. 
  Few 
  of 
  these, 
  

   however, 
  have 
  been 
  procured, 
  owing, 
  in 
  part, 
  to 
  a 
  defect 
  

   in 
  the 
  law 
  authorizing 
  the 
  Survey, 
  and 
  to 
  the 
  illness 
  and 
  

   subsequent 
  resignation 
  of 
  Dr. 
  Millington, 
  the 
  principal 
  

   Professor 
  of 
  Geology 
  and 
  Chemistry, 
  in 
  the 
  State 
  Uni- 
  

   versity. 
  

  

  The 
  latter 
  event 
  occurring 
  at 
  a 
  period 
  so 
  nearly 
  ap- 
  

   proaching 
  to 
  that 
  at 
  which 
  a 
  report 
  of 
  the 
  progress 
  of 
  

   the 
  Survey 
  was 
  required, 
  devolved 
  unexpectedly 
  upon 
  

   the 
  assistant 
  that 
  duty, 
  which, 
  under 
  the 
  existing 
  cir- 
  

   cumstances, 
  must 
  otherwise 
  have 
  been 
  unperformed. 
  

  

  Interrupted 
  by 
  a 
  severe 
  and 
  protracted 
  indisposition,
