that  there  was  no  longer  any  reason  to  oppose  the  system  of  green- 
ing preserved  vegetables  by  means  of  the  salts  of  copper." 
Consequently  it  is  now  allowable  in  France  to  use  salts  of  copper 
for  preserving  the  green  color  in  food  products  in  any  amount, 
although  until  the  harmlessness  of  this  metal  became  known  it  was 
forbidden  to  even  use  a  copper  vessel  for  preserving  purposes.

VI.  GERMANY  I   CIVILIZED  AND  UNCIVILIZED. 
When  the  readers  see  this  the  great  Louisiana  Purchase  Ex- 
position will  be  a  thing  of  the  past.  It  will  ever  be  kept  green  in 
minds  of  the  millions  that  attended,  by  pleasant  memories  of  pike, 
of  grand  palaces  and  of  magnificent  displays  of  the  wonders  of 
nature  and  the  handiwork  of  man.  To  those  who  come  after  us,  it 
will  probably  be  known  as  the  exposition  of  the  grand  prize.  As  a 
visitor  during  the  last  month  of  the  fair,  it  seems  that  this  highest 
award  has  been  bestowed  on  a  most  lavish  scale.  We  find  exhib- 
itors in  the  same  lines  who  each  boast  of  this  highest  honor,  while 
many  have  an  array  of  gold  medals  to  set  off  the  parchment. 
Entering  Germany's  chemical  exhibit,  we  find  that  it  is  not  with- 
out its  full  quota  of  these  mementos ;  in  fact,  to  use  a  familiar  ex- 
pression, they  may  be  said  to  be  "  it."  At  least  thirty-three  grand 
prizes  have  been  decreed  to  our  Saxon  brethren  for  superiority  in 
this  field  alone  by  the  superior  jury.  Of  gold  medals  they  receive 
thirty-one ;  the  number  of  minor  prizes  need  not  be  mentioned. 
Germany,  in  the  pharmaceutical  and  chemical  lines,  cannot  be 
said  to  make  a  commercial  display ;  in  fact,  they  themselves  make 
no  pretensions  in  this  line,  for  the  big  firms  cared  not  to  go  to  an- 
other great  expense  so  soon  after  the  Paris  Exposition,  especially  as 
the  high  tariff  is  a  bar  to  the  successful  exploitation  of  many  chemi- 
cal goods  of  strict  commercial  value  in  the  United  States. 
The  underlying  idea  ot  the  Germans  to  make  at  this  exposition 
an  Unterrichts  Ausstellung  has  been  carried  out  with  a  certain  degree 
of  success.    This  method  naturally  brings  to  the  mind  the  idea  of  a
