^D]  OCCURRENCE    AND    DISTRIBUTION    OF    TIN.  163 
Maine. — Tin  occurs  at  Winslow  in  a  number  of  narrow  veins  in 
ca-schist.  The  veins  are  composed  largely  of  lepidolite  and 
arite,  holding  cassiterite,  beryl,  and  mispickel.  This  deposit  was 
:e  worked,  but  with  little  success.  Cassiterite  has  also  been  found 
small  amount  at  Paris  and  Hebron. 
Vew  Hampshire,  Massachusetts,  and  Connecticut. — Cassiterite  oc- 
-s  at  Lyme  and  at  Jackson,  N.  IT.,  in  narrow  veins  carrying  also 
irtz,  mispickel,  chalcopyrite,  fluorite,  and  phosphate  minerals, 
e  mineral  has  been  found  at  Goshen  and  Chesterfield,  Mass., 
ociated  with  albite  and  tourmaline.  At  Haddam,  Conn.,  a  few 
rstals  have  been  found. 
Vew  York  and  New  Jersey. — Tin  has  been  reported  from  the  high- 
Lds  of  New  York  and  New  Jersey  as  sparingly  present  in  the 
gnetite  deposits. 
West  Virginia. — In  Mason  and  Cabell  counties  cassiterite  has  been 
ind  in  quantities  only  of  miner  a  logical  importance. 
Virginia. — Several  finds  of  tin  ore  have  been  reported  from  Nel- 
l  County.  The  most  important  locality,  however,  is  in  Rock- 
dge  County,  near  the  headwaters  of  Irish  Creek.  Cassiterite 
s  discovered  there  about  1883,  and  considerable  attention  has  been 
iwn  to  the  region  at  various  times  since.  The  best  known  prop- 
y  is  the  Cash  mine,  7  miles  east  of  Vesuvius  station  on  the  Nor- 
k  and  Western  Railway.  Narrow  quartz  veins  cut  a  coarse 
lined  granite  and  carry  bands  of  minerals,  of  which  cassiterite, 
spickel,  pyrite,  wolframite,  and  beryl  «re  the  most  important, 
lorite  and  siderite  have  also  been  found.  The  granite  adjoining 
i  veins  is  largely  converted  into  scaly  muscovite  mica  and  is 
pregnated  with  cassiterite.  It  is  said  that  the  ore  will  average 
>er  cent  cassiterite. 
k.  small  amount  of  development  work  was  done  some  years  ago 
1  a  large  mill  erected.  Work  was  abandoned  soon  afterwards, 
)bably  more  because  of  poor  management  than  of  proof  that  the 
Dosit  was  not  valuable.  Some  prospecting  was  done  in  the  region 
ring  the  summer  of  1904. 
Vorth  Carolina  and  South  Carolina. — Dikes  of  pegmatite  carry- 
;  cassiterite  as  an  original  constituent  occur  in  a  belt  crossing  Lin- 
,  Gaston,  and  Cleveland  counties,  in  North  Carolina,  and  extend- 
into  Cherokee  County,  S.  C.     Tin  ore  was  found  in  place  in  1886, 
since  that  time  more  or  less  work  has  been  done.     The  cassiterite 
rs  concentrated  in  certain  parts  of  the  dikes,  but  the  distribu- 
of  these  rich  portions  is  irregular.     Work  is  now  being  carried 
ilwith  gratifying  results  at  the  Ross  mine,   near  Gaffney,  S.   C, 
I  at  the  Jones  mine,  north  of  Kings  Mountain,  N.  C.     It  is  prob- 
li  that  good  ore  bodies  carrying  over  2  per  cent  cassiterite  will  be
