derfully  rapid  development  of  an  American  dye-color  industry  is 
perhaps  the  most  striking  feature  illustrated  by  these  successive  ex- 
positions. Within  the  past  year  several  of  the  most  important  of 
the  American  dye-color  works  have  been  united  under  the  name  of 
"  The  National  Aniline  &  Chemical  Co.,  Inc."  This  combination  in- 
cludes the  Schoellkopf  Aniline  &  Chemical  Works  of  Buffalo,  N. 
Y.,  the  W.  Beckers  Aniline  &  Chemical  Works  of  Brooklyn,  N.  Y., 
The  National  Aniline  &  Chemical  Co.  of  New  York,  the  Benzol 
Products  Co.  of  Marcus  Hook,  Pa.,  and  the  Standard  Aniline  Prod- 
ucts, Inc.,  of  Wappingers  Falls,  N.  Y.,  together  with  certain  plants 
and  properties  of  the  General  Chemical  Co.,  the  Barrett  Co.  and 
the  Semet-Solvay  Co.  With  these  has  also  been  incorporated  most 
recently  the  Cassella  Color  Co.  (American  branch)  who  have,  under 
the  name  of  the  Century  Color  Corporation,  taken  over  the  selling 
agency  of  the  whole  combination.  The  exhibit  was  a  collective  one 
as  far  as  the  dye-colors  are  concerned,  and  was  a  most  impressive 
one.  Almost  the  whole  range  of  standard  coal-tar  dyes  was  repre- 
sented, as  well  as  a  long  list  of  so-called  "  intermediates  "  and  many 
organic  chemicals  and  drugs  available  for  the  pharmaceutical  pro- 
fession and  the  synthetic  perfume  industry. 
There  were  quite  a  number  of  other  manufacturers  and  dealers 
in  intermediates  and  raw  materials  of  the  dye-color,  the  perfume 
and  the  pharmaceutical  industries. 
The  way  in  which  American  chemists  and  manufacturers  have 
responded  to  the  needs  of  war-time  is  also  shown  in  the  way  in 
which  chemical  glassware  and  porcelain  ware  of  superior  quality, 
equal  to  the  best  Jena  glass  or  the  best  Berlin  porcelain,  are  now 
offered.  Whitall-Tatum  Glass  Co.  and  the  Macbeth-Evans  Glass 
Co.  were  among  the  most  prominent  of  the  glass  supply  firms,  while 
the  Ohio  Pottery  Co.  and  the  Coors  Chemical  Porcelain  Co.  of  Col- 
orado supplied  the  porcelain.  For  the  general  equipment  of  the 
chemical  manufacturer  with  specially  designed  apparatus,  can  be 
mentioned  the  Buffalo  Foundry  and  Machine  Co.,  which  had  the 
largest  and  most  striking  single  exhibit,  showing  fusion  kettles, 
nitrators,  vacuum  dryers,  evaporators,  etc. ;  the  J.  P.  Devine  Co.,  the 
Bethlehem  Foundry  &  Machine  Co.,  the  Walter  E.  Lummus  Co., 
the  Swenson  Evaporator  Co.,  and  the  United  Lead  Co.  For  special 
lines  of  apparatus,  instructive  exhibits  were  also- shown  as  the  pyrom- 
eters of  the  Brown  Instrument  Co.  and  the  Bristol  Co.,  and  the  cen- 
trifugal separators  of  the  De  Laval  Separator  Co.  and  the  Sharp-
