RECENT  WORK   ON   NEW    ENGLAND  GRANITES

By  T.  Nelson   Dale. 
AREA   CONSIDERED. 
During  the  summer  of  1905  the  writer  visited  all  the  import  nut  gran] 
ite  quarries  in  Maine,  and  in  L906  all  those  at  the  chief  granite  centers 
of  New  Hampshire,  Massachusetts,  and  Rhode  [sland,  namely,  Con-B 
cord,  Conway,  and  Milford,  in  New  Hampshire;  Milford,  Quincy,  and 
Rockport,  in  Massachusetts,  and  Westerly  and  Niantie  in  Rhode 
Island.  The  quarry  at  Chester,  Mass.,  was  also  visited.  The  State] 
of  Maine  cooperated  with  this  Survey  in  bearing  the  expense  of  the 
work  in  its  territory,  hut  the  work  in  the  other  States  was  done  entirely 
at  the  expense  of  the  Tinted  States  Geological  Survey. 
WORK   IN   MAINE. 
The  results  of  the  Maine  work  are  soon  to  be  presented  in  a  bulletin 
entitled  "The  granites  of  Maine/'  to  which  Dr.  George  Otis  Smith  has 
contributed  an  introductory  chapter  and  map  showing  the  geographic 
and  general  geologic  relations  of  the  granites  in  thai  State.  The  bulle- 
tin will  also  include  the  statistics  of  granite  production  in  Maine  for 
1905,  prepared  by  Miss  A.  T.  Coons. 
A  brief  outline  of  this  forthcoming  report  on  the  Maine  quarries  may 
be  of  interest  to  person^  engaged  in  the  granite  industry. 
The  number  of  quarries  and  prospects  visited,  including  those  of 
"  black  granite"  for  monumental  use,  amounted  to  129.  The  capital 
invested  in  the  entire  Maine  granite  industry  in  1905  amounted  to 
about  $3,500,000.  This-estimate  is  based  upon  fair  valuations  of  the 
quarries  themselves,  of  the  plants,  and  of  the  amount  of  "working  cap- 
ital" that  is  required  to  carry  on  the  present  business. 
The  report  is  designed  to  be  helpful  to  those  who  are  engaged  in 
quarrying  and  working  granite,  as  well  as  to  architects,  contractors,  and 
dealers  in  monumental  stone,  and  it  will  also  make  known  to  geologists
