  The 
  hole 
  is 
  about 
  midway 
  between 
  Sterling 
  Station 
  and 
  the 
  west 
  

   end 
  of 
  Oneida 
  lake, 
  an 
  interval 
  that 
  seems 
  to 
  be 
  barren 
  of 
  workable 
  

   deposits. 
  More 
  tests 
  are 
  needed, 
  however, 
  to 
  demonstrate 
  their 
  

   entire 
  absence, 
  since 
  the 
  distance 
  to 
  the 
  Martville 
  locality 
  is 
  10 
  

   miles 
  and 
  to 
  Brewerton, 
  the 
  next 
  drill 
  site 
  to 
  the 
  east, 
  about 
  12 
  miles. 
  

  

  Brewerton, 
  Onondaga 
  co. 
  The 
  drill 
  was 
  set 
  up 
  on 
  the 
  south 
  

   shore 
  of 
  Oneida 
  river, 
  within 
  the 
  village, 
  about 
  75 
  yards 
  west 
  of 
  

   the 
  bridge. 
  This 
  point 
  is 
  very 
  near 
  the 
  Oswego-Onondaga 
  county 
  

   border 
  and 
  the 
  south 
  line 
  of 
  the 
  route- 
  followed 
  by 
  the 
  new 
  Barge 
  

   canal.

  Olive-gray 
  shale 
  with 
  many 
  

   dark 
  bands 
  in 
  the 
  lower 
  part 
  and 
  

   with 
  few 
  thin 
  bands 
  of 
  limestone. 
  

   At 
  19 
  feet 
  there 
  is 
  a 
  4 
  inch 
  band 
  

   with 
  black 
  pebbles.

  Shale 
  with 
  limestone 
  bands 
  3 
  to 
  

   4 
  inches 
  thick 
  found 
  at 
  quite 
  

   regular 
  intervals. 
  The 
  limestone 
  

   contains 
  cavities 
  lined 
  with 
  crys- 
  

   tals. 
  Traces 
  of 
  ore, 
  as 
  threadlike 
  

   veinlets, 
  are 
  found 
  in 
  the 
  lime-

  Shale

  Oolitic 
  ore. 
  

  

  The 
  layers 
  below 
  the 
  ore 
  are 
  

   quite 
  variable. 
  The 
  2 
  inches 
  

   immediately 
  below 
  the 
  ore 
  is 
  

   shale 
  ; 
  then 
  follows 
  a 
  sandstone 
  or 
  

   conglomerate, 
  becoming 
  coarser 
  

   toward 
  the 
  bottom. 
  

  

  This 
  section 
  is 
  similar 
  to 
  the 
  one 
  at 
  South 
  Granby 
  in 
  showing 
  

   two 
  ore 
  seams 
  separated 
  by 
  many 
  feet 
  of 
  rock. 
  The 
  absence 
  of 
  

   limestone 
  is 
  a 
  striking 
  feature 
  and 
  serves 
  to 
  connect 
  this 
  section 
  

   with 
  the 
  eastern 
  development 
  of 
  the 
  Clinton, 
  as 
  exemplified 
  in 
  

   Oneida 
  and 
  Madison 
  counties, 
  rather 
  than 
  the 
  western 
  belt. 
  This 
  

   is 
  further 
  indicated 
  by 
  the 
  oolitic 
  structure 
  of 
  the 
  lower 
  ore 
  seam. 
  

  

  The 
  16-inch 
  bed 
  is 
  solid 
  ore 
  of 
  uniform 
  character. 
  It 
  will 
  repay
