I  have  thus  sketched  the  development  and  establishment  of  a 
number  of  chemical  industries  of  distinctively  American  origin.  My 
iist  is  not  intended  to  be  an  exhaustive  one.  It  could  readily  .have 
been  extended.  It  is  enough,  however,  to  show  that  we  have  done 
very  creditably  and,  in  fact,  have-  done  much  more  than  is  generally 
known  to  the  public. 
As  I  said  in  beginning  these  remarks,  "  With  the  wonderful 
richness  of  this  country  in  the  raw  materials  which  lie  at  the  basis 
of  chemical  industries,  and  with  the  well-known  inventive  and 
mechanical  turn  of  our  people,  we  would  be  greatly  disappointed 
if  we  did  not  find  some  results  in  the  way  of  the  establishment  of 
new  and  distinctive  lines  of  manufacture  and  the  production  of  new 
products." 
So  much  for  the  establishment  of  new  industries.  However, 
unless  the  supply  of  raw  materials  is  so  specially  limited  to  the 
country  as  to  preclude  their  becoming  available  elsewhere,  a  time 
will  come  for  an  important  industry  when  the  manufacture  be- 
comes competitive  in  an  international  sense.  Then  a  national  policy 
with  regard  to  established  industries  becomes  of  the  greatest  im- 
portance. Legislation  can  foster  these  industries  in  a  great  variety 
of  ways,  or  it  can  hamper  them  so  that  international  competition 
soon  puts  them  at  a  disadvantage. 
If  we  are  to  maintain  our  chemical  manufactures  already  begun 
and  reach  out  for  a  stronger  and  more  independent  position  in  in- 
dustrial chemistry,  the  matters  of  legislation,  the  tariff,  and  our 
patent  laws  must  be  given  intelligent  thought  and  such  action  taken 
as  will  give  us  a  fair  show  in  the  world's  competition.  As  that 
is  a  large  subject,  involving  many  considerations,  I  will  not  enter 
upon  it  here. 
THE  EXAMINATION  OF  CHAULMOOGRA  OIL.

Botanical  Observations. 
Chaulmoogra  oil  of  commerce  is  obtained  from  a  large  variety 
of  seeds.  According  to  the  Indian  and  Colonial  Addendum  ( 1900) 
to  the  British  Pharmacopceia  (1898),  the  oil  is  expressed  from  the 
seeds  of  Gynocardia  odorata.  But  subsequent  identification  by 
Colonel  Prain  proved  that  the  oil  is  really  obtained  from  the  seeds
