Montpelier,  and  the  dips  are  to  the  west  at  widely  varying  angles. 
There  is  a  bed  of  phosphate  here  which  corresponds  in  its  general 
character,  thickness,  and  grade  to  the  main  bed  at  Montpelier  and, 
at  several  places  where  it  is  opened  up,  dips  from  20°  to  30°  to  the! 
west.  It  is  overlain  by  a  band  of  limestone  in  which  OmpJialo- 
trocJius  and  Chonetes  have  been  recognized.  Above  this  band  of 
limestone  there  is  the  usual  succession  of  beds  of  phosphate,  lime- 
stone, and  shale.  In  places  this  phosphate  bed  is  faulted  and  appar- 
ently lies  over  a  massive  limestone  in  which  a  large  Productus  is 
found.  Work  is  being  undertaken  to  trace  out  the  sequence  and 
extent  of  the  phosphate  beds  at  this  locality.
