It  has  been  found  convenient  to  group  the  articles  in  relation 
to  their  use  as  products,  and  then  to  subdivide  these  larger  divi-

or  as  in  the  case  of  foods  and  drugs  from  root  to  seed. 
The  rest  of  the  bulletin  is  taken  up  by  a  comprehensive  cata- 
logue of  exhibits  with  clear  descriptive  notes.
