sections 22, 27 and 34, lies a point of land one and one-half mile long and 
one mile wide. The top of this point is formed of limestone, which varies 
in thickness at different places around the point. 
Near the center of section 34 the line of parting between the limestone~ 
and knobstone is 150 feet above the bed of the river. Farther north, near 
the south side of section 27, the line of parting is 140 feet above the river. 
At the north end of the point of land_in section 22 the line of parting is 
only 110 feet above the river, with 40 feet of limestone above, and at the, 
northeast corner of the land the line of parting is only 60 feet above Twin 
Creek. At this point the overlying limestone is 100 feet thick. 
At the south side of section 26 the knobstone is only 40 feet thick and 
is overlaid with 160 feet of limestone, while at the corresponding point on 
the west side the knobstone is 140 feet thick, with only 20 feet of lime- 
stone. 
Near the bridge across Twin Creek in the northeast quarter of the 
northeast quarter of section 35 the line of parting is only 20 feet above 
the creek, and is overlain with 150 feet of limestone. 
A well section near the northeast corner of section 27 shows the fol- 
lowing strata: Soil, 35 feet; limestone, 10 feet; knobstone, 88 feet. 
On the west side of a tributary of Twin Creek, at the east center of 
section 35, the line of parting is only 20 feet above the creek bed, while on 
the east side the hill is 190 feet high, without limestone. From the line of 
parting on the west side of the branch to the school house at the center of 
section 35 there is 150 feet of limestone, but from the school house west 
there is only a descent of 50 feet to the line of parting at the west side of 
the section. Fig. 4. 
On the east side of the point of land between White River and Twin 
Creek the upper ledges of limestone form a cliff some 12 or 15 feet high. 
On the west side there is no cliff, and the exposures are covered over 
largely with debris. 
In the center of section 26 is a point that extends to the southwest 
some 400 yards from the high sand hills east of the creek. The average 
height of this projection is about 100 feet. With the exception of 20 feet 
of knobstone at the base of this projection, the rocks are all limestone. 
The adjoining hill to the northeast rises 150 feet above the projection and 
is formed of knobstone. 
On the north side of the projection and west of the wagon road are 
two ditches some 30 yards apart. In the ditch farthest east there is an
