the  war,  and  that  this  company  is  now  the  largest  producer  of  ani- 
line oil  in  the  world. 
The  cooperation  of  producers  of  coal  tar  and  its  "  crudes  "  with 
the  manufacturers  of  "  intermediates "  and  the  dyestufT  manufac- 
turers was  obviously  a  very  desirable  thing  in  the  building  up  of  the 
new  industry  and  establishing  it  on  a  firm  foundation.  Such  co- 
operation has  been  planned  in  the  organization  of  our  largest 
American  dye  manufacturing  company.  As  they  announce  in  their 
statement,  "  the  various  plants  of  this  company  are  engaged  in  pro- 
ducing everything  necessary  for  dye  manufacturing,  commencing 
with  the  basic  raw  materials  or  "  crudes  "  derived  directly  from  coal, 
with  the  acids  and  other  chemicals  converting  these  crudes  into  dye 
"  intermediates,"  which  are  also  used  for  explosives,  and  the  manu- 
facture finally  of  the  several  classes  of  dyes  demanded  by  the 
industries. 
In  this  combination  we  have  the  Semet-Solvay  Co.,  and  the  Bar- 
rett Manufacturing  Co.,  the  General  Chemical  Co.,  the  Benzol 
Products  Co.  furnishing  "  crudes "  and  "  intermediates,"  and  the 
Schoellkopf  Aniline  and  Chemical  Works,  Buffalo,  N.  Y.,  the  W. 
Beckers  Aniline  and  Chemical  Works,  Brooklyn,  N.  Y.,  the  Century 
Color  Corporation,  Nutley,  N.  J.,  and  the  Standard  Aniline  Products 
Co.,  Wappinger's  Falls,  N.  Y.,  producing  "  intermediates  "  and  fin- 
ished "  dye  colors."  All  the  raw  materials  are  the  product  of  Amer- 
ican factories  as  well  as  the  finished  products. 
The  "  intermediates  "  listed  by  the  National  Aniline  and  Chem- 
ical Co.  amount  to  58  distinct  substances  and  the  dyes  named  to 
nearly  two  hundred. 
Other  of  our  American  color  manufacturers  ha\Te  additional  dis- 
tinctive dye-colors  as  well  as  many  the  equivalents  of  those  in  the 
list  referred  to.  Truly  a  satisfactory  showing  for  what  is  prac- 
tically a  newly  created  industry  at  the  end  of  the  fourth  year  since 
the  start  was  made. 
The  Tariff  Census  of  191 7  before  referred  to  makes  the  follow- 
ing statement :

of  products  made  in  whole  or  in  part  from  material  derived  from
