THE  LIME  INDUSTRY  OF  KNOX  COUNTY,  ME. 
By  Edson  S.  Bastin. 
DISTRIBUTION  OF  THE  LIMESTONES. 
The  limestones  of  Maine  which  are  utilized  commercially  in  the  production  of  lime  are 
confined  to  Knox  County.     The  limestone  areas  form,  in  general,  long,  narrow,  somewhat 
irregular  strips  trending  northeast  and  southwest  and  surrounded  by  quartz  rocks  and 
i  schists.     The  largest  continuous  area  extends  from  Chickawaka  Pond,  2  miles  north  of 
:  Rockland,  in  a  southwesterly  direction,  somewhat  over  5  miles,  to  Thomaston,  where  its

southernmost  exposures  are  seen  in  the  yard  of  the  State  prison.  In  some  places  this  belt 
has  a  width  of  nearly  a  mile,  although  all  of  the  rock  is  not  of  commercial  quality.  The 
second  largest  deposit  extends  from  the  east  shore  of  Rockport  Harbor,  near  the  Henry 
Cottage,  northward  to  Lily  Pond  and  thence  assumes  a  more  westerly  trend;  it  takes  in 
the  Jacobs  quarry  on  the  trolley  road  between  Rockport  and  Camden  and  extends  to  the 
west  of  this  road  for  a  little  over  a  mile.  After  a  short  interruption  the  same  belt  appears 
again  just  west  of  Simontons  Corners,  where  it  includes  the  Eelfe  quarry.  (See  fig.  13.) 
Next  in  commercial  importance  is  the  deposit  occurring  2  miles  northwest  of  the  village  of
