AMKRICAN STORAX PRODUCTION 



n 



care in collection and more frequent gatherings, somewhat higher 

 yields might be secured. The samples of gum furnished contained 

 considerable trash, which was removed by filtering. The absorbed 

 gum was dissolved from the filtered trash by extraction with 95 per 

 cent alcohol, which was then evaporated. The amount of storax 

 obtained from each group of trees tapped by the same method is given 

 in Table 1.

Table 1. — Atnount of storax obtained by diffcroit methods of tapping. 



The largest yield of storax was obtained by the horizontal tapping 

 of the trees, and was secured during hot August weather. The cost 

 per pound of storax collected in the experiment was $2.37, which 

 promised only a small profit. During the war the wholesalers sold 

 storax to the trade at $4 a pound. Considering the fact that the men 

 engaged on the experiment were inexperienced, and that the results 

 from the methods producing the lower yields were included in deter- 

 mining the cost figures per pound, it is estimated that the commercial 

 production price can be reduced at least 50 per cent.
