It  has  already  become  an  important  factor  in  the  in-
dustrial life  of  Teesside,  and  hardly  to  a  less  extent  in  that
of  Tyneside,  whose  chemical  works  are  no  longer  dependent
upon  the  distant  salt  fields  of  Cheshire  and  Worcestershire,
but  now  obtain  their  supplies  of  salt  from  the  apparently
^xhaustless  stores  imderlying  the  banks  of  the  sister  river.
Cleveland  Salt  is  also  fast  superseding  that  of  the
Southern  counties  for  the  use  in  the  East  Coasts  Fisheries,
in  Iceland,  and  in  some  of  the  North-West  Ports  of  Europe,
and  has  even  been  shipped  round  to  the  chemical  works  of
the  Clyde.  It  will  not,  therefore,  be  surprising  to  learn
that  the  output  during  the  past  year  nearly  reached  220,000
tons,  or  rather  more  than  the  total  consumption  of  salt  by
the  Tyne  chemical  works.
It  is  expected  that  this  quantity  will  in  a  short  time  be
doubled,  as  these  various  works  are  being  rapidly  extended.
Messrs.  Tennant  &  Co.  have  recently  put  down  four  additional
evaporating  pans  at  Haverton  Hill,  with  a  view  to  making
domestic  or  table  salt,  the  adjoining  works  owned  by  the
Salt  Union  being  hitherto  the  only  works  where  salt  of  this
description  was  produced.

The  Cleyeland  Salt  Co.  have  recently  erected  six  large
pans  for  the  utilisation  of  the  waste  heat  from  the  Middles-
borough  blast  furnaces,  and  the  Salt  Union  are  at  present
erecting  pans  to  be  heated  in  like  manner  from  the  fumaoes
at  Clarence  Iron  Works.  The  system  of  having  the  pans
driven  by  waste  heat  frOm  the  blast  furnaces  is  an  advantage
of  which  the  full  value  can  only  be  realised  in  times  of  dear
fuel  like  the  present.
