regions passes under this black soil. But farther out into the black soi.. 
the silt underneath almost pinches out. The low region containing the 
black soil was undoubtedly the centre of the basin in former times, even 
as it is now. This low-lying, fertile region is very near the 720-foot cou- 
tour line; thus it is some forty feet below the silt line at the foot of the 
hills surrounding. 
It was said that the slope of the basin is generally toward the mathe- 
matical center; this is not true specificaliy, as there are some excep- 
tions. Several places considerably elevated occur. The large one in 
Section 31, T. 10 N., R. 2 W. reaches to the height of 795 feet, approxi- 
mating the peripheral regions. A well shows that bed rock is near the 
surtace of this old monadiock. In section 36, west of the above, a long 
arm-like island projects out into the basin, and near the south of the 
middle of the section a notch occurs in the arm, which almost separates tie 
north end, leaving a round-like knob projecting some forty feet above the 
basin. This elevation also has bed-rock in it near the surface. Section 
25, T. 10 N., R. 3 W. has two elevations some twenty feet above the gen 
eral level of the basin. It was not determined whether these had bed-rock 
near the surface, but indications are, especially in the western one, that 
it is there at a shallow depth. The elevation on the section line between 
sections 26 and 35, T. 10 N., R. 38 W. is a rounded knoll about twenty-five 
feet above the general level of the basin. Indications are that it con- 
tains no bed-rock. The northern part of Section 6, T. 10 N., R. 2 W., con- 
tains a slight elevation, perhaps twelve feet above the low-lying area 
adjacent. A deep well proves that it contains no bed-rock. Southeast 
in section 5, und entering section 8, is a long elevation parallel to the long 
axis of the basin and about twenty feet high. A well proves that this one 
also contains no bed-rock. 
While dealing with the irregularities of the surface of the basin, at- 
tention must be called to the depression at the scuthwestern edge of Flat- 
woods, on the section line between sections 2 and 3, T. 9 N., R. 3 W. This 
depression, containing about two acres, is the site of a small lake which is 
being rapdly filled by in-wash and vegetation. The elevation of the sur- 
face of this small lake, bearing the name of Stogsdill Vond, is about 770 
feet. It is enclosed on three sides by sloping banks which reach tiurty 
feet above the water. It is open on the north. 
The south bank of Stogsdill Pond is the lowest opening to a sort of 
an adjunct to the Flatwoods basin. The surface of this adjunct slopes
