PRACTICAL DIRECTIONS FOR THE USE OF THE REMEDY. 



A practical course of treatment based on the use of boric acid 

 was accordingly outlined for tests on the factory basis. Since the 

 paste evaporates water between the time of making and of using, a 

 concentration somewhat less than saturation was recommended in 

 making the paste. This would also tend to decrease the liability of 

 the acid to crystallize out in a conspicuous way on the surface of 

 the cigars should paste happen to be smeared on them. The fol- 

 lowing concise directions were prepared: Place boric acid in warm 

 water at the rate of 1 ounce of dry acid to If pints of water. Stir 

 till the acid is all dissolved. Use this solution instead of water in 

 making up the paste. Great care should be taken not to use more 

 paste on the cigar than is necessary, since it is liable to be smeared 

 on the surface of the cigar, where the boric acid in the paste tends 

 to crystallize, giving an appearance suggesting mold. 



These directions have been followed for some years in the fac- 

 tory in which the complaints originated, and when the writer was 

 last in communication with those in charge the boric-acid treat- 

 ment was in use as a routine practice and only in rare instances 

 were molds found troublesome.
