Barren Forest Formation. On the extremely rugged area which forms 
the watershed between the Coosa and Tallapoosa rivers, the steep hills of 
silicious cherts and obdurate sandstone which reach scarcely an elevation of 
1000 or 1200 feet, support an inferior growth of Ouercus Prinus, O. marylan- 
dica, O. tinctoria (= O. velutina), O. falcata (= O. digitata), Q. obtusiloba 
(= O. minor), Carya porcina (= Hicoria glabra) and Pinus palustris, scantily 
interspersed between the trees and stunted specimens of Sassafras, Rhus copal- 
lina and glabra. 
The flats of the Coosa Valley are covered with a low forest of dwarfed 
trees of Ouercus marylandica and obtusiloba, scarcely over 20 feet high with 
equally stunted Pinus taeda and with a few specimens of Pinus mitis and 
P. inops scattered among them, while the association of Crataegus crus-galli, 
C. spathulata, C. apiifolia with the trees form an impenetrable thicket in which 
also grows Nyssa multiflora supporting Smilar bona-nox and laurifolia. 
The extreme southern spurs of the western Alleghanian ranges including 
the Cumberland Mountains and all of the strata of the lower coal measures 
and underlying subcarboniferous rocks were in Alabama originally covered by 
an uninterrupted forest of a varied growth of hardwood trees and conifers. 
On the bread expanse of the tablelands above 900 or 1000 feet Quercus Prinus 
largely prevails associated with other species of oak; also with Castanea, 
Carya tomentosa (= Hicoria alba) and C. porcina = (H. glabra), Nyssa sylvatica 
and the smaller Oxydendrum arboreum. 
The tableland of Sand Mountain is covered by an almost unbroken forest 
rather open in character and it presents a varied growth of deciduous trees 
interspersed with Pinus mitis and P. taeda. The largest part of the area is 
occupied by a forest consisting of oaks, chestnut and hickory with Zirio- 
dendron. Pinus mitis is found more or less frequently scattered among the 
hardwood trees, wherever a sandy or drier soil prevails. Pinus taeda prefers 
a damp or wet soil. With the improvement of the soil Quercus alba, 
©. ae O. obtusiloba became more prominent in the forest growth ’).
