380         CONTRIBUTIONS    TO    ECONOMIC    GEOLOGY,  1906,  PART    I, 
In  January,  1907,  a  trial  of  this  sand  was  begun  at  the  works  of  the 
Fredonia  Window  Glass  Company.  The  sand  was  hauled  by  wagol 
to  the  works  and  was  found  to  make  glass  of  excellent  quality. 
Near  the  town  of  Fall  River  the  Buxton  sandstone  is  exposed  at 
several  places  by  the  drainage  system  of  Fall  River.  The  sandstone 
here  is  about  20  feet  thick  and  is  parted  near  the  middle  by  a  thin  clay? 
seam.  The  upper  bed  of  sandstone  is  generally  iron  stained,  espe- 
cially at  the  top  and  immediately  above  the  clay  seam.  Below  the 
clay  seam  is  4  to  5  feet  of  very  clean,  grayish-white,  angular  sand- 
stone, rather  friable.  This  deposit  is  close  to  the  Frisco  Railroad 
tracks.  West  of  the  town  it  would  have  to  be  quarried  from  a  pit, 
hut  east  of  the  town  it  rises  in  a  Mull*  that  stands  about  30  feet  above 
railroad  level.  Ajssociated  with  the  sandstone,  but  somewhat  above 
the  beds  just  described,  i-  a  lime-tone,  probably  the  Painterhoodl 
which  might  be  quarried  at  the  same  time  and  used  for  glass  making. 
Analysis  of  a  -mail  -ample  of  this  rock  by  George  Steiger,  of  the 
United  States  Geological  Survey,  is  as  follows:

a  belt  of  saccharoidal  sandstone,  which  is  exposed  at  the  top  of  the 
escarpment  overlooking  the  ravines  at  the  headwaters  of  Little

stained  quartzite,  in  some  places  cherty.  The  rock  strikes  northeast!

by  cherty  beds  and  a  very  line-grained  sandstone  or  "cotton  rock.''

with  the  thick  masses  of  cannel  coal  that  are  found  here  in  pockets  or 
sink  holes.  The  apparent  thickness  of  the  sandstone  reaches  25  feel 
in  places,  although  the  actual  thickness  may  be  less  than  this,  since 
the  exposures  are  principally  on  hillsides  that  slope  in  the  direction  of]
