SECTION FROM THE MISSISSIPPI RIVER TO POUND GAP. I Gm 
in low places, as well as black ash, black gum, sweet gum, 
black and. red oak, pawpaw, black sumach, and redbud. 
Undergrowth is chiefly black oak and red oak. These tim- 
bers vary little until Bole’s Creek is reached, about three- 
miles from Columbus. On the creek are found sycamore, 
red elm, liriodendron, white oak, black and honey: locust, 
sweet gum, white walnut, small black walnut, and consider- 
able sugar maple and black ash. 
Five miles out from Columbus, toward Mayfield, the forests. 
grow heavier and more valuable, white oak forming a consid- 
erable percentage of the timbers (as much as fifty per cent. in 
low places), liriodendron about twelve per cent., the remain- 
der being composed of black and pig hickory, red oak, black 
oak, some scarlet oak, white and red elm, sweet and black 
gum, and sycamore. The country ts rolling, with long, damp, 
white-sandy levels. 
About five and three quarter miles out the first swamp. 
laurel oak, the first white maple, and the first winged elm 
of any size are found. On Elsey Branch, a mile further 
on, shag hickory and pin oak first appear—the latter very 
large and fine. The other timbers remain as above noted, 
with occasionally a fine black ash. 
Eight and one half miles from Columbus one prickly ash 
occurs. The timbers otherwise remain without change until 
North Fork of Obion river is reached, eleven miles out. 
There the first swamp chestnut oak appears. Spanish oak 
also begins to grow very prominent in these.forests, and to 
form more than one half of the upland oaks. The first post 
oak seen appears between North Fork of Obion river and 
Milburn. 
Four miles beyond Milburn, toward Mayfield, the Purchase 
pebbles come to the surface, and a thin, dry soil, covered with 
post oak, scrubby black oak, &c., is the result. These peb- 
bles are the waste of the decayed mill-stone grit, and are 
found in every part of the Purchase at a greater or less 
depth below the surface. Upon it white oak is not found; 
but while, as a formation, it is very dry, it brings the streams.
