80 PLANT LIFE OF ALABAMA. 
lands were made easily accessible to the immigrant by the great trunk 
lines leading from the centers of population in the North to the Gulf 
coast, they were but sparsely inhabited. The earlier settlers who had 
squatted upon them depended for their support more on the chase than 
upon the cultivation of a soil which was looked upon as too poor to 
afford an adequate return, This, however, has all been changed by the 
influx of a population which was attracted by the mild and salubrious 
climate, and which, coming with the determination to establish its home 
here, has succeeded in conquering the unpromising soil and developed 
its possibilities. With the rapid increase in population these lands 
have come much into demand, and under rational management almost 
every crop raised in the Northern States can be successfully grown on 
these table-lands by the side of cotton. 
The meadow grasses of the North, with red clover and similar for- 
age plants, do well here. Much attention is given to the production 
of breadstuffs, chiefly corn, to which the greater part of the arable 
land is devoted. Small grains, as wheat and rye, supply a part of the 
home demand. Lrish and sweet potatoes are profitable summer crops, 
and nearly all of the root crops and vegetables grown in the temperate 
zone are produced here in abundance and perfection. Of small fruits, 
the strawberry has been found highly profitable, usually being har- 
vested before the end of April. This fruit finds a ready sale in the 
distant northern markets. Orchards of fruit trees on a large scale 
do not yet exist, although apples, pears, and peaches are successfully 
grown. The cultivation of the grape was given great attention by 
the earlier of the German immigrants until the appearance of a fun- 
gous disease proved a great drawback. But with the successful 
employment of remedies to subdue this disease viticulture, particu- 
larly of grapes for table use, has received a new impetus. 
REGION OF THE TENNESSEE RIVER VALLEY. 
PHYSIOGRAPHICAL FEATURES AND CLIMATE, 
West of the detached spurs of the Cumberland Mountains, which 
form the northeastern continuation of the table-lands south of the 
basin of the Tennessee River, this valley is marked as an area of 
erosion, in which the waters have cut their channel altogether in the 
subcarboniferous limestone, the surface rock. The most distinctive 
feature of the vegetation of the Tennessee Valley consists in decid- 
uous forests, generally of a mesophile composition, with decidedly 
northern types prevailing, and containing species in common with the 
Carolinian area in the Ohio Valley which are not found in any other 
part of Alabama, For example. of trees and shrubs there occur here: 
Aesculus vetandra (buckeye). Staphylea trifolia (bladderwort). 
Aesculus glabra (buckeye). Symphoricarpos — symphoricarpos — (coral- 
Acer saccharum (sugar maple). berry). 
Cladrastis tinctoria (yellowwood).
