  The 
  samples 
  were 
  all 
  dried 
  at 
  212° 
  Y. 
  

  

  It 
  may 
  be 
  of 
  interest 
  in 
  this 
  connection 
  to 
  give 
  the 
  composition 
  

   of 
  some 
  other 
  clays 
  found 
  at 
  Warner, 
  which 
  are 
  used 
  in 
  the 
  manu- 
  

   facture 
  of 
  cement.

  The 
  last 
  analyses 
  would 
  indicate 
  a 
  rather 
  fusible 
  clay. 
  The 
  

   clay 
  used 
  by 
  the 
  Onondaga 
  co. 
  is 
  dug 
  in 
  a 
  field 
  adjoining 
  the 
  works. 
  

   It 
  has 
  a 
  pinkish 
  color, 
  stratified 
  and 
  runs 
  about 
  15 
  feet 
  in 
  depth.
