Englemann in the Geol. Sur. 111., Ill, 148, as follows:
Upper sandstone formation 200-250 feet.
(Worthen considers the thickness here given an over-
estimate, and thinks 100 feet to be a much nearer ap-
proximation).
Shoal Creek limestone 7 feet.
Slaty division 15-50 "
Lower sandstone formation 270 "
The Quaternary, which covers the county as with a
blanket, varies from ten to fifty feet, and at some points
is still thicker. But few outcrops embracing any consid-
erable vertical thickness, were met with.
SECTION X.
Outcrops on Williams creek, on the south half of sec-
tion 22, township 2 south, range 4 west. Top section

No. 5, in the above, presents a peculiar appearance.
Undoubtedly a coal measure stratum and in situ, it
showed, irregularly distributed on the face of the expos-
ure, two large, exceedingly hard limestone boulders and
one sandstone boulder, and a large number of pebbles,
the whole reminding one of some deposits of the drift
formation. Is this debris of an ancient iceberg or glacier
166
a carboniferous glacial period? Unfortunately, hut a
few feet were exposed, so that nothing definite could be
ascertained.

and at Nashville, at Oakdale Coal No. 6 will be found at
a depth of about 340 feet below the surface.

If No. 46 is really the No. 6 coal, which seems to be
the general opinion, the general section of the Coal Meas-
ures given in Geol. Sur. 111., VI., 2-4, does not give suffi-
cient thickness of strata between Coal No. 6 and the
Shoal creek limestone. In 1889 a drill hole was put
down at Nashville to the depth of 1,000 feet, or some-
what more, but if a record was kept, about which there
is some dispute, repeated efforts have failed to obtain it.

A short distance below where the section was taken,
fragments of the Shoal Creek Limestone were found in the
bed and on the banks of the creek, but no outcrops could
be found showing the limestone in place. Hence 1 could
not determine how great a distance intervened between
the Coal No. 9 and the Shoal Creek Limestone at this
point.
SECTION XVII.
Outcrops adjacent to Little Muddy river, on the west
half of section 27, township 3 south, range 1 west. Top
of section about 510 feet above sea level.

Perry County.
The line of the section passes diagonally through the
northeast township of the county. The few surface out-
crops are near the dividing line between the Upper and
Lower Coal Measures. A bed of sandy shale, about 15
feet thick, was seen near Little Muddy river, on the north-
east quarter of section 3, township 4 south, range 1 west,
the same bed as No. 1 in Section XVI.
170
SECTION XVIII.
Outcrop on northeast quarter section 13, township 4
south, range 1 west. (Geol. Sur. 111., Ill, 96). Top of
section is about, 485 feet above sea level.

2. Hard, bluish-gray limestone (Shoal Creek) 5
3. Shale 4 " 6 inches.
4. Coal No. 9 1 foot.
6. Clay shale 6 feet.
Total thickness 19 feet 6 inches.
Jefferson County.
The line of the section cuts diagonally the southwest
corner of Jefferson county. The very few surface exposures
represent the lowest strata of the Upper Coal Measures,
the Shoal Creek Limestone being but a short distance
beneath the surface.
SECTION XIX.
Outcrop on Little Muddy river and adjacent hillside,
near the line between sections 30 and 31, township 4
south, range 1 east. Top of section about 480 feet
above sea level.
1. Sandy shale 10 feet.
2. Interval not exposed, probably shale 10 "
3. Sandstone, soft, ferruginous, partly massive, partly
evenly stratified 8 "
Total thickness 28 feet.
Franklin County.
The surface of the northern part of the county tra-
versed by the line is rolling, but presents no great
variation in altitude, hence outcrops are few, and
but limited in vertical extent. The Quaternary varies
from 10 to 30 feet in thickness. All the outcrops belong
to the lower part of the Upper Coal Measures.
On a small branch in section 5, township 5 south,
range 2 east, an exposure of three feet of micaceous
171
sandstone was seen. No other exposures were met on
the Big Muddy river or its affluents in the northwestern
part of the county.
Two miles north of Ben ton, on the west half of section
6, township 6 south, range 3 east, an outcrop of about
thirty feet of soft, brownish, ferruginous sandstone, with
some sandy shale interstratified, has been quarried for
building purposes.
About two and one-half miles northeast of Benton, in
the northeast quarter of section 9, township 6 south,
range 3 east, an outcrop of soft, ferruginous, micaceous
sandstone, of about 20 feet, underlaid with two or more
feet of clay shale, with concretions, usually of small size,
of kidney iron ore, and with the fragmentary remains
of fossil plants, occurs on a small branch. A little far-
ther on, near the center of section 36, township 5 south,
range 3 east, the wagon road cuts through sandstone
and sandy shale, exposing about six feet.
In a small run in township 7 south, range 4 east, on
section 12, probably was seen an exposure of clay shale,
with concretions of kidney iron ore.
These were all the outcrops examined in Franklin
county. The only boring at all near the line, of which
I could learn, and it too shallow to give much informa-
tion, is the following section.
SECTION xx.

Hamilton County.
But one small exposure was discovered in the south-
western corner of Hamilton county, about one-half mile
east of the county line, on section 6, township 7 south,
range 5 east, where about six feet of a micaceous sand-
stone outcropped.
Saline County.
The geological formations outcropping, are:
Upper Coal Measures.
Lower Coal Measures.
Chester Group.
The exposures of the Chester are in an axis of uplift
in the southeastern part of the county, several miles
southwest of the line, known as the Eagle mountains.
The few outcrops discovered belong to the Upper Coal
Measures.
About one-half mile north of Gallatia, some 25 feet of
shale are exposed, with about three feet of the underly-
ing sandstone.

Nos. 1-27 may be regarded as Lower Coal Measures
proper; Nos. 28-37 as the Conglomerate. The dividing
line is seldom well marked, and may be drawn somewhat
higher or somewhat lower in the series without doing
any violence. No. 38 marks the highest limestone of the
Chester Group. This makes the thickness of the con-
glomerate 480 feet at this point very much greater
than has been hitherto thought. Prof. A. H. Worthen,
in the Geological Survey of Illinois, volume VI, pp. 2-5,
where an exhaustive section of Coal Measures strata is
given, says that the thickness of the coarse sandstone
or conglomerate forming the base of the Coal Measures,
usually range from 20 to 110 feet. Possibly only Nos.
35-37 should be regarded as Conglomerate; this gives
a thickness of 130 feet. In this event, there is a vastly
greater accumulation of strata between the Conglom-
erate and Coal No. 1 than is given in Prof. Worthen's
section above referred to.
176
SECTION XXVI.
Outcrop on bank of Ohio river, in front of Shawnee-
town. (Compare Geol. Sur. 111., VI, 198). Strata all
dip to the south, at an angle varying from 10 to 25.
Estimates of thickness are somewhat doubtful approxi-
mations. The vertical thickness of the strata is given,
not the amount of space occupied horizontally. The sec-
tion crosses the upturned edges from north to south.
1. Black shale, with concretionary bands of clay iron-
stone interstratified 15 feet.
2. Hard, black, bituminous shale. 6 "
3. Coal 2 "
4. Bluish shale, with irregular beds of thin, fine-grained
sandstone interstratified 12 "
5. Shale, gray or dove-colored 10 "
6. Arenaceous shale 6 "
7. Argillaceous shale 30 "
8. Sandstone, hard, fine-grained 20 "
9. Shale and sandstone, layers alternatirg 10 "
10. Shale, arenaceous, micaceous 3 "
11. Sandstone, fine-grained 10 "
12. Shale, bluish, arenaceous, micaceous 4 "
IS. Sandstone, ferruginous 30 "
Total thickness 158 feet.
14. Interval not exposed.
15. Sandstone, soft, ferruginous, horizontal, exposed, 5 feet.
The indications are that there is a fault between Nos.
13 and 15, but the limited examination 1 could make,
and the insufficient exposure, furnished me no da.ta for
establishing the surmise.
These strata belong to the lowest part of the lower
Coal Measures, in part to the basal sandstone known
as the Conglomerate.
177
Geological Section in Southern Illinois through Water-
loo, Sparta, Murphy sboro and Olmstead.
Introductory.
This line essentially parallels the Mississippi River at
a distance from it of from 15 to 20 miles. Beginning
with the Lower Carboniferous it crosses the southwestern
border of the Lower Coal Measures, again issues upon
the Lower Carboniferous and leaves the State after pass-
sing through the Tertiary in Pulaski county. The line
changes direction at Sparta and Murphy sboro, bending
each time more towards the south.
Monroe County.
Monroe is one of the most interesting counties in the
State to the geologist and paleontologist. The outcrop-
ping strata over a large part of the county belong to
the Lower Carboniferous, or Subcarboniferous, for which
term Mississippian is now being substituted, a formation
abounding with a wealth of fossils often exquisitely pre-
served. In the extreme northern part the county is
crossed by an axis of disturbance, bringing to the sur-
face some of the lower formations; entering from Mis-
souri the uplift causes quite a dislocation near Salt Lick
Point, and disappears southeastwardly.
The following table of geological formations, having
surface outcrops, is taken from the Geol. Sur. 111. V., 270.
Coal measures 40- 50 feet.
Chester group 100-350 '
Upper St. Louis limestone 140-150
Lower St. Louis or Warsaw beds 120-130 '
Keokuk limestone 150 '

Kinderhook group 80-100 '
Trenton limestone, (in part) 120 '

No boring could be found which would give an idea
of the underground geology. An artesian well was put
down at Waterloo some years ago, but no record seems
to have been kept. The time at my disposal was too
limited to enable me to make much exploration of the
surface outcrops.
SECTION xxvn.
Outcrops along Fountain Creek on sections 27 and 34,
township 2 south, range 10 west. Stra,ta dip to the
west at a low angle. Top of section about 540 feet
above sea level. All strata belong to the St. Louis
group.
1. Limestone, in layers from four inches to four
feet thick, with occasional shaly or marly
partings between layers, fossiliferous,
some layers weathering cherty 15 feet.
2. Limestone, cherty fossils numerous, mainly
bryozoa and brachiopoda 5 "
3. Limestone, quarried for building purposes .. 12 "
4. Marl layer with a peculiar assemblage of
small fossils, mainly gesteropoda, pen-
tremites and bryozoa, varying in thick-
ness from 2 inches to 10 inches, averaging " 6 inches.
5. Limestone 4 "
6. Marly or shaly layer contains most abund-
antly an undescribed species of stenopora " 4 inches.
7. Limestone, fossiliferous 5 "

SECTION XXVIH.
Outcrop on small branch flowing into Prairie du Long
creek, on west half of section 21, township 3 south,
range 8 west. Top of section about 450 feet above sea
179
level. All the strata belong to the Chester group, but
the exact position in the series has not been determined.
1. Limestone layers with shaly partings 8 feet.
2. Limestone layer 2 "
3. Limestone layers with shaly and marly part-
ings 5 "
4. Limestone layer 1 foot.
5. Shale and marl with thin slabs of limestone
intercalated. 9 feet.
6. Limestone layer " 8 inches.
7. Limestone layers with shale partings 4 feet 6 "
8. Blue marly shale 1 foot 3 "
9. Limestone layers 4 feet.
Total thickness 35 feet 5 inches.
All the limestones in the above sections are fossiliferous,
but the shales and marls much more so. Brachiopods,
pentremites and fragments of crinoids are common, but
the bryozoa are by far the most numerously represented,
the genera Fenestella, Archimedes and Rhombopora
leading in representation. More examples of the rare
Coelocomus granosus, Ulrich, have been obtained from
this locality than from any other though it is a widely
distributed form.
My studies in the Chester Group confirm the earlier
observations of Prof. Worthen, that the different beds
of the Chester so much resemble each other lithologically
and in their fossil contents, that the identification of
the various beds, either by their fossils or lithological
characters, is impossible. It may be that long-continued,
painstaking, patient collection and study of the fossils
will serve to discover some distinctive or particular
horizons, so that eventually we may be able to say just
where in the series any given outcrop belongs; but at
present, unless continuous outcrops showing relative
superposition give the clue, we are unable to place any
given outcrop in its proper place.
180
Randolph County.
The geological formations seen at the surface in this
county are the Lower Coal Measures, including the
Conglomerate, the Chester Group and the St. Louis
Group. The line of the section cuts the northern and
eastern parts of the county, and all the outcropping
strata passed over belong to the Chester and Lower
Coal Measures.
It is in this county that the Chester has its typical
development; for comparison with what follows, Prof.
Worthen's tabular presentation is given. (Geol. Sur.
111., I, 284).
Chester Group.
1. Gray, compact, siliceous limestone No. 1 25-30 feet.
2. Shale and shaly sandstones, partially exposed ... 80-'.: '
3. Shaly limestone No. 2 15-18 "
4. Massive brown sandstone 40
5. Limestone No. 3 40-45
6. Green and blue argillaceous shales, with plates
of limestone 45-70
7. Arenaceous and argillaceous limestone No. 4 20-^0
8. Massive and shaly sandstone 15-20
9. Compact and granular gray limestone No. 5, with
intercalations of blue, green and purple shales,
about 150 "
10. Massive quartzose brown sandstone 120 "
I have, in this report, adopted the numbering of the
limestone beds as given above, though afterwards, in the
reports of the Geological Survey, in the chapters describ-
ing the geology of Johnson, Massac, Pope and Hardin
counties, the beds are differently numbered.
Whether detailed study will bear out this division into
five different successive limestone beds, each with an un-
derlying sandstone except No. 3, I am not prepared to
say. There may also be some doubt whether these sand-
stones are continuous over wide areas.

SECTION XXIX.
Strata displayed in hillside northwest of court house
at Chester, 111., from top of hill to river level (ten feet
of water in the channel).
1. Not exposed, elsewhere shown to be sandstone in
lower part 73 feet.
2. Limestone 1 foot.
3. Green, blue and purple shales 12 feet.
4. Limestone, regularly bedded 10 "
5. Limestone, irregularly bedded, partly nodular and

fossiliferous in places (Lyropora shale) 53 "
7. Compact gray limestone 27 "
8. Not exposed, elsewhere seen to be limestone mainly. . 46 "
Total thickness 264 feet.
Nos. 4 and 5, above, are the Limestone No. 3 of the
general section; No. 7, above, is the Limestone No. 4;
and No. 8, above, is probably Limestone No. 5, in which
case there is no sandstone at this place between Lime-
stones Nos. 4 and 5. To No. 6 of the section above, I
have given the name of Lyropora shale. It forms an
easily recognized horizon, in which the bryozoan Lyro-
pora, to whose stony supports, with the fenestration
between lost or broken away, the name "frog mouths"
has been popularly applied, is very characteristic. I have
not yet succeeded in ascertaining whether the Lyropora
is restricted to this shale and the underlying limestone,
but at any rate it is rare, or wanting in strata higher
in the series.
