 about 28 gallons. In the long continued experience which 

 Bulgaria has had in the production of this perfume it has been 

 found that from 2,500 to 2,600 pounds of flowers are required 

 to produce I pound of the perfume. Experiments with modern 

 steam stills seem to give less satisfactory results than the primi- 

 tive stills which have long been in use in Bulgaria.
