Figure 13. — Closed tobacco-storage warehouse one story high, divided into sections bv 

 fire walls. This warehouse was fumigated periodically during 1932 for the control of 

 the tobacco moth. 



Figure 14. — Hogsheads of flue-cured tobacco in storage. These hogsheads may remain 

 here from 2 to 4 years during the aging period, and the tobacco moth may inflict severe 

 damage unless the warehouse is fumigated periodically.
