QUERCUS SUBER. CORK OAK. 
That the cork oak will attain a fair size in 
the Southern States is shown by this halftone of a 
small group of trees growing at Augusta, Georgia. 
No data are available concerning these trees, but 
they are supposed to have been grown from seed 
introduced by the Division of Forestry (now Forest 
Service) in 1891. Seeds from these trees or from 
others in the vicinity have been received for dis- 
tribution by the Forest Service under S.P.I. No. 
34710. Cork oaks grow to a height of 45 feet, rare- 
ly more, and are stripped of their bark first when 
they reach a diameter of about 16 inches. If left 
to themselves the bark is coarse, deeply creviced, 
and of no value for the production of cork, but. if 
demasclage, or removal of the coarse outer bark Is 
practiced, the inner bark grows to a considerable 
thickness and after an interval of ten or more years 
is removed. Five or six such harvests are yielded 
by the tree before the bark is exhausted as a cork 
producer, after which the bark may be used as a 
source of tannin. From photograph presented by the 
P. J. Berckmans Company, Augusta, Georgia.
