Anticline in Southern Minnesota. — Foerste. 363 
It seems, therefore, that along both flanks of the Cincinnati 
anticHne the Corniferous extends farther south than the Ham- 
ilton. 
It is probable that most of the Devonian limestones be- 
tween the Ohio river and central Kentucky belong- to the Cor- 
niferous. However, no attempt has been made as yet to keep 
separate the faunas belonging to different horizons and to de- 
termine their geological position accurately. It is possible 
therefore that other horizons, above or below the Corniferous 
may be present, especially at those localities where the Devo- 
nian limestone has a thickness of 20 feet or more. 
Devonian limestone is frequently exposed on the crest of 
the Cincinnati anticline between Loretto and Stanford, and 
also along the many branches of Rolling Fork, and in the 
vicinity of Moreland and McKinney. It is absent however 
on the crest of the anticline along the Cumberland river and 
in northern Tennessee. The probable southward extension of 
the Devonian limestone is indicated on the accompanying map 
as well as our present knowledge will permit. 
The Devonian limestone extends farther south along the 
flanks of the anticline than along its crest. 
• In Tennessee, Devonian limestone occurs at the bridge 
west of Pegram, about 18 miles west of Xashville. At the 
thickest part of the section 11 feet of Corniferous are over- 
laid by I foot of Hamilton. 
On a recent visit to the area along Fishing creek, east of 
the crest of the Cincinnati anticline in Kentucky, in company 
with Prof. Arthur M. Miller, Devonian limestone was dis- 
covered outcropping for a distance of about 7 miles along the 
creek. The most southern outcrop detected occurred along 
the branch separating the farms of Mrs. Al Loval and Sol 
Jones. Here the limestone is 3^ inches thick and is overlaid by 
coarse sandy material, half an inch thick. About a quarter 
of a mile northward, along the Sulphur Spring branch, the 
Devonian is 2^ feet thick ; it consists, in descending order, 
of coarse sandstone, 6 inches ; fine grained bluish limestone, i 
foot 9 inches ; and brecciated rock, 4 to 6 inches. A mile and 
a half northward, just above John Freeman's house, the De- 
vonian limestone is 4 feet thick ; most of it is white and cri- 
uoidal, containing Cyathophylloid corals and large Spirifcrs.
