and about Mount Atlas,” where it forms a tree from 15 ft. to 20 ft. high, 
with round branches, clothed with rusty down when young. The leaves are 
twice or thrice as long as those of Q. coccifera, thicker, and less wavy, with 
much smaller and shorter spinous serratures, rather than teeth. Introduced

Varieties. These, we have no doubt, are as numerous as the varieties of Q. 
Ilex, in countries where the tree is indigenous. None are in cultivation in 
British gardens under any particular name: but, the cork trees having been 
all raised from seed, their leaves will be found to vary in magnitude, in 
different places, in length relatively to breadth, and in the character of their 
margins, which are wavy, serrate, or dentate. :

The cork tree bears a general resemblance to the broad-leaved kinds of Q. 
Ilex; of which species some authors consider it only a variety: but, when 
full grown, it forms a much handsomer tree ; and its bark alone seems to jus- 
tify its being made a species. The outer bark, the great thickness and elasti- 
city of which are owing to an extraordinary developement of the cellular tissue, 
forms the cork ; which, after the tree is full grown, cracks and separates from 
it of its own accord. The inner bark remains attached to the tree, and, 
when removed in its young state, is only fit for tanning. The wood of the 
cork tree, which weighs 84 lb. per cubic foot, is used for the same purposes 
as that of Q. J‘lex ; but it is never found of sufficient size to be of much
