In  southwestern  Missouri,  near  Butterfield,  Barry  County,  on  the  main  line  of  the  Fris<  > 
Railroad,  is  a  deposit  of  sandstone,  reported  to  be  more  than  36  feet  deep,  outcropping  »  , 
the  surface  or  l\  ing  below  a  few  feel  of  soil.     Three  or  four  ears  of  sand  have  been  shippe 
from  this  place.

In  the  north-central  and  northwestern  pari  of  Arkansas,  particularly  along  the  valley  o 
White  River  from  Batesville  nearl)   to  Fayetteville,  exposures  of  the  St.  Peter  sandston< 
,iim1  Sylamore  (Devonian)  sandstone  are  common.     Those  deposits  thai   face  the  rive 
between  Batesville  and  Cotter  on  the  White  River  Branch  of  the  Missouri  Pacific  Railway 
are  in  many  places  admirably  situated  for  economical  quarrying  and  transportation,  am 
so  far  as  a  cursory  e.xaminat  ion  would  indicate  t  hey  arc  of  an  excellent  grade  of  g*Iass  sand 
Survey  publications  relating  to  this  region  are  as  follows:   Batesville,  Mountain   Home

119  of  the  Geologic  Atlas  of  the  United  States),  1905.     The  sandstone  mapped  as  "  Key' 
in  the  Yellville  quadrangle  a  is  frequently  of  suitable  quality.     Near  Everton,  on  the  east 
side  of  the  valley  of  Clear  Creek.  is  a  bed  25  feet  or  more  thick  of  good  white  saccharoicUl 
sandstone,  ao  situated  that  it  will   not  require  much  stripping  and  also  convenient  to  the 
railroad.      Analyses  of  this  sandstone  appear  on   pages    162    163  (No.  9),  and  show    it   to  he 
of  desirable  quality.     The  Sylamore  sandstone  mapped   in   the   Fayetteville  quadrangle,! 
along  White  River,  is  within  5  miles  of  the  railroad  at   Rogers  and  adjacent  to  a  railroad  at 
Sulphur  Springs.

The  topographic  maps  of  the  [ola,  Fredonia,  Independence,  and  Sedan  quadrangle! 
include  Hi.'  area  here  considered.  The  area!  geology  of  the  Independence  quadrangle  was 
mapped  in  L904  l»\  F.  C.  Schrader,  who  make-  i  he  following  statement :c 
In  a  number  of  localities  along  t  he  western  side  of  t  lie  Independence  quadrangle,  in  i  lie  Buxton  (on 
mation  •   occurring  in  bodies  of  from  one-eighth  to  one-half  mile  in  extenl  is  .  if  such  purity 
fineness,  and  evenness  of  grain  as  t<>  give  promise  of  usefulness  in  the  manufacture  of  glass.  The 
besl  quality  occurs  in  heavy  beds  in  which  the  rock  h  I  affected  or  stained  by  the  leaching 
of  descending  surface  waters.  Exposun  -  occur 4  miles  northwesl  of  Canej  and  2  miles  north  of  Caneyl 
At  the  latter  locality  the  long  hill  is  capped  bj  sandstone  having  a  thickness  of  al  leasl  10  feet,  other 
exposures  occur  farther  north.  Perhaps  the  besl  is  in  the  southern  pari  of  Fall  River  Township,  in 
tin  si-:,  j  see.  22,  aboul  1  miles  southwesl  ol  Fredonia.  Here  the  rock  is  exposed  over  an  area  of 
id  oi-  l.")  acres,  and  as  nearly  as  can  be  judged  from  some  local  prospecting  thai  has  been  done  and  froni 
the  topography,  it  is  aboul  12  feet  in  t bickness. 
Samples  of  tin-  rock  were  taken  in  October,  L905,  from  each  of  the  above  localities  and 
wereanalyzed  in  the  laboratory  of  the  Survey,  with  the  results,  Nos.  1  8,  page  462.  Other 
exposures  of  the  formation  in  the  vicinity  of  Fredonia  were  also  sampled.
