  very 
  odd, 
  the 
  broad 
  and 
  notched 
  base 
  having 
  elevated 
  points 
  on 
  either 
  

   side. 
  It 
  is 
  from 
  the 
  Seneca 
  river, 
  and 
  is 
  of 
  Hght 
  brown 
  flint, 
  one 
  

   and 
  three 
  eighths 
  inches 
  long. 
  Fig. 
  167 
  is 
  a 
  frequent 
  form, 
  with 
  a 
  

   broad 
  and 
  deep 
  base, 
  which 
  in 
  some 
  may 
  be 
  widest 
  above 
  or 
  below. 
  

   Sometimes 
  the 
  contraction 
  above 
  the 
  base 
  is 
  very 
  moderate 
  at 
  first. 
  

   This 
  is 
  of 
  common 
  flint, 
  and 
  is 
  one 
  and 
  one 
  quarter 
  inches 
  in 
  length. 
  

   It 
  is 
  one 
  of 
  the 
  frequent 
  forms. 
  Fig. 
  168 
  is 
  one 
  of 
  the 
  largest 
  and 
  

   oddest 
  of 
  this 
  variety, 
  and 
  comes 
  from 
  Brewerton. 
  It 
  is 
  of 
  brown 
  

   flint, 
  and 
  the 
  broad 
  and 
  curving 
  base 
  has 
  obtuse 
  raised 
  points, 
  

   strongly 
  suggestive 
  of 
  those 
  in 
  a 
  drill 
  already 
  figured. 
  The 
  length 
  is 
  

   two 
  inches, 
  and 
  it 
  is 
  nearly 
  as 
  broad. 
  

  

  Some 
  of 
  these 
  expanding 
  bases 
  suggest 
  the 
  gimlet 
  and 
  thumb- 
  

   screw, 
  and 
  might 
  have 
  been 
  used 
  with 
  or 
  without 
  an 
  additional 
  

   handle, 
  but 
  the 
  straight 
  and 
  slender 
  ones, 
  if 
  used 
  for 
  perforating, 
  

   would 
  have 
  required 
  a 
  handle 
  of 
  some 
  kind. 
  Fig. 
  169 
  is 
  a 
  small 
  ex- 
  

   ample 
  of 
  the 
  thumb-screw 
  pattern, 
  the 
  three 
  arms 
  being 
  much 
  alike, 
  

   though 
  one 
  is 
  a 
  Httle 
  longer 
  and 
  narrower 
  than 
  the 
  others. 
  It 
  is 
  of 
  

   drab 
  flint, 
  one 
  and 
  one 
  eighth 
  inches 
  long, 
  and 
  could 
  be 
  easily 
  turned 
  

   by 
  the 
  fingers. 
  This 
  is 
  from 
  Seneca 
  river, 
  and 
  another 
  from 
  Brewer- 
  

   ton, 
  two 
  inches 
  long, 
  presents 
  the 
  same 
  concave 
  base. 
  This 
  is 
  carried 
  

   still 
  farther 
  in 
  fig. 
  170, 
  a 
  specimen 
  unfortunately 
  broken, 
  where 
  the 
  

   wide 
  base 
  is 
  almost 
  as 
  slender 
  as 
  the 
  shaft. 
  One 
  prong 
  terminates 
  in 
  

   a 
  notched 
  and 
  rounded 
  point, 
  as 
  if 
  for 
  suspension, 
  and 
  it 
  is 
  a 
  question 
  

   whether 
  the 
  broken 
  part 
  had 
  the 
  same 
  feature, 
  as 
  is 
  probable, 
  or 
  

   whether 
  it 
  was 
  a 
  double 
  pointed 
  drill. 
  It 
  is 
  of 
  black 
  flint, 
  two 
  and 
  

   one 
  half 
  inches 
  long, 
  and 
  comes 
  from 
  the 
  Seneca 
  river. 
  A 
  smaller 
  

   one, 
  somewhat 
  like 
  this 
  but 
  with 
  a 
  narrower 
  base, 
  was 
  found 
  on 
  the 
  

   Canajoharie 
  flats. 
  The 
  one 
  figured, 
  however, 
  is 
  unique 
  in 
  some 
  

   respects. 
  ! 
  

  

  Fig. 
  171 
  is 
  a 
  good 
  example 
  of 
  the 
  gimlet 
  form 
  from 
  Onondaga 
  lake. 
  

   It 
  is 
  of 
  grey 
  flint, 
  two 
  and 
  one 
  half 
  inches 
  long, 
  and 
  very 
  symmetrical. 
  

   One 
  from 
  Geneva 
  is 
  almost 
  equally 
  so, 
  and 
  is 
  two 
  inches 
  in 
  length. 
  

   This 
  form 
  is 
  rarely 
  perfect, 
  from 
  its 
  great 
  liability 
  to 
  injury, 
  but 
  more 
  

   might 
  be 
  described. 
  Among 
  those 
  having 
  deeper 
  expanded 
  bases 
  is 
  

   one 
  of 
  rosy 
  quartz, 
  one 
  and 
  three 
  quarters 
  inches 
  long. 
  This 
  is 
  also 
  

   from 
  Geneva, 
  where 
  many 
  small 
  forms 
  have 
  been 
  found. 
  There 
  are
