required. For the heavy type of leaf which is 

 intended for the export trade, the curing in the 

 sheds is done by an open fire, the fuel being 

 usually hardwood logs. The smoky, creosotic 

 flavor is absorbed by the leaf, and, although 

 this flavor is not relished by the smokers of the 

 U. S., it is much liked in Europe. The curing 

 in such cases may last for 4 or even 5 five days. 

 The tobacco is suspended on poles by the stalks 

 and the fires are built on the floor immediately 

 under them so that the carbonaceous products 

 are easily absorbed by the open pores of the 

 leaf. 



The chewing and pipe smoking tobacco, as 

 well as cigarette tobaccos including all the 

 bright yellow tobaccos used in the U. S. are 

 usually cured by Flue curing. In this case 

 the heat comes from pipes which run around the 

 curing houses and are fed from a furnace in an 

 adj oining chamber or in a cellar. The tempera- 

 ture can be easily regulated. "Flue" curing is 

 generally completed in about 4 days. "Flue" 

 curing does not clog up the pores of the leaf 

 which therefore remain more absorbent than in 

 the open fire cured tobacco. This is an import- 

 ant matter for the manufacturers because the 

 flue cured leaf will absorb twice as much of the 

 flavoring sauces (which are added to certain
