THE  OTTO  OF  ROSE  INDUSTRY. 
Mr.  Ernst  Schmalfuss,  a  German  horticulturist,  has  been  spend- 
ing a  considerable  time  in  Bulgaria  to  investigate  the  conditions  of 
the  otto  of  rose  industry  in  that  country.  Mr.  Schmalfuss  went  to 
Bulgaria  as  the  agent  of  a  German  firm  of  essential  oil  distillers 
who  have  lately  been  endeavoring  to  create  an  otto  of  rose  indus- 
try in  Germany,  and  who  desired  to  have  an  expert's  opinion  on 
the  question  whether  it  is  feasible  to  grow  the  Thracian  rose  in 
Western  Europe. 
The  information  which  has  been  collected  belongs  of  course  to 
the  firm  who  bore  the  expense  of  the  journey,  but  Mr.  Schmalfuss 
has  obtained  their  permission  to  publish  certain  details  on  the  sub- 
ject of  his  investigations.  Mr.  Schmalfuss  went  to  Bulgaria  with 
an  open  mind,  and  returned  thence  a  firm  believer  in  the  future  of 
an  otto  industry  in  Western  Europe.
