THE  CLAY  DEPOSITS  OF  WASHINGTON. 
By  Henry  Landes. 
INTRODUCTION. 
The  value  of  the  clay  products  of  Washington  in  1903  amounted 
to  nearly  $1,000,000.  The  value  of  such  products  in  1898  was  only 
one-quarter  as  much,  thus  showing  a  very  large  gain  in  six  years.  In 
a  State  as  lately  settled  as  Washington  it  is  not  surprising  that  com- 
mon bricks  represent  more  than  one-half  the  value  of  the  clay  prod- 
ucts. As  the  towns  have  grown  into  cities  and  the  small  cities  have 
become  larger  and  wealthier  the  use  of  pressed  and  ornamentall 
brick,  ornamental  terra  cotta,  and  similar  products  has  increased! 
very  rapidly.  With  the  growth  of  the  municipalities  there  has  come' 
a  demand  for  permanent  improvements  and  larger  and  larger  quan- 
tities of  vitrified  brick  and  sewer  pipe  are  used  each  year.  The  great; 
increase  in  the  number  of  farms  has  caused  a  sharp  rise  in  the  demand 
for  draintile.  The  discovery  of  clays  of  a  good  grade  has  led  tc 
the  manufacture  of  stoneware  and  higher  grades  of  pottery  to  supply 
the  local  demand.
