SALT  IN  IDAHO  AND  NEVADA. 
A  correspondent  of  the  San  Francisco  Bulletin,  writing  from 
Soda  Springs,  Idaho,  says: — This  community  are  at  present 
deeply  interested  in  the  workings  of  the  Oneida  Salt  Company, 
a  corporation  duly  formed  under  the  Territorial  laws  for  the 
purpose  of  manufacturing  salt,  with  a  capital  stock  of  $1,000,000, 
divided  into  1,000  shares,  and  pocketed  by  a  few  original 
locators.  The  Company,  I  understand,  have  commenced  opera- 
tions upon  a  large  scale.  The  grounds  of  this  company  are 
situated  upon  the  Lander  Cut-off  Emigrant  Road,  about  250 
miles  north  from  Salt  Lake  City,  and  about  60  miles  north  from 
this  place.  I  have  conversed  with  Messrs.  Penwell  &  Stump, 
the  President  and  Secretary,  and  learn  that  upon  their  land  are 
situated  a  number  of  large  springs,  with  a  flow  of  about  150 
inches  of  water,  which,  after  a  thorough  test,  have  been  found 
to  yield  one-third  pure,  fine  table  salt  when  boiled.  The  Com- 
pany have  erected  works  to  produce  100,000  lbs.  per  month. 
The  expense  which  will  necessarily  accrue  in  the  manufacture 
of  this  amount  will  not  exceed  one  quarter  cent  per  pound,  and 
for  which  there  is  a  natural  market  in  the  mines  of  our  sister 
Territory,  Montana,  with  a  nett  profit  of  not  less  than  ten  cents 
per  pound.  These  springs  have  been  known  for  years — emi- 
grants passing  over  that  road  having  spoken  of  them  in  the 
highest  terms,  and  a  mere  lack  of  energy  has  permitted  them 
to  be  unappropriated.  The  consumption  of  salt  in  mining 
counties  is  very  great,  and  the  productions  of  the  springs  will 
supply  the  demand.  The  mineral  wealth  of  this  country  is  yet 
undeveloped,  but  will  not  be  so  long.  Many  prospectors  from 
a  distance  have  already  found  their  way  hither  with  the  deter- 
mination of  thorough  examination  in  the  early  spring.  A  num- 
ber of  mines  (placers)  are  now  being  worked  in  and  about  Salt
