168 GEOLOGY OF ILLINOIS. 



A mile up stream the coal is four feet above the water, and a quarter 

 of a mile further it is two feet above, and capped by 12 feet of gray 

 shale, passing into thin beds of sandstone. 



J. Gallagher's coal on Eichland creek, in sec. 33, T. 10 N., E. 4 E., is 

 capped by about 30 feet of sandy and argillaceous shales. South of this 

 on Brush creek we have shales above, with dark lead-blue shaly lime- 

 stone, containing remains of fossils, just over the coal. 



At Win. A. Eudy's, in the north half of the south-east quarter of sec. 

 14, T. 9 N., E. 3 E., the coal is 18 inches thick, with clay shales above, 

 and blue tire clay beneath. The hills here are about 50 feet high. 



At Mrs. Matthews', a quarter of a mile east, the coal is capped by 2 

 inches of dark lead blue calcareous shale. Half a mile down Eichland 

 creek it is 20 feet above the water, with 5 feet of yellow clay beneath, 

 resting on 16 feet of thin-bedded, dark gray and brown sandstone. 



In sec. 6, T. 9 X., E. 4 E., the section is — 



Ft. In. 



1. Olive clay shales 4 



2. Bituminous coal I 6 



3. Fire-clay 2 



4. Buff limestone, fracture gray 4 



The coal at this place is seen occupying the bed of a small dry branch, 

 and is easily taken out. On laud of S. Syfert's, near by, the coal is a 

 little thicker. On Mrs. Fanchei's land, in the S. E. qr. sec. 32, T. 10 

 N., E. 4 E., we have — 



Ft. In. 



1. Argillaceous shales 



2 Coal 22 



3. Fire clay 5 



4. Sandstone in thin beds, alternating rough, hard, with gray ripple marked, and thicker 



brown beds ^ 15 



I saw a very good grindstone that had been made from the last named 

 sandstone. 

 The following is a section at Lilly's mill, in sec. 1, T. 9 N., E. 3 E.: 



Ft In. 



1. Slope gentle 60 



2. Drift clay, sand and pebbles 10 



3. Ash-blue clay shale .' -. 4 



4. Calcareous shale, changing to shaly limestone to 3 



5. Coal 22 



6. Fireclay 3 



7. Hard and soft shales, shaly and thkkly -bedded gra}- and grayish-felue, very changeable 



within a short distance 20 



No. 4 at one place is separated by a two-foot bed of clay shale from 

 No. 5, and becomes a firm but thinly laminated limestone. At the 

 mouth of Long Branch in sec. 10, T. 10 N., E. 3 E., we have : 



Ft. 



1. Brown ash-clay, a few pebbles in the lower part 20 



2. Bituminous coal, the upper one foot has thin bands of clay shale— the lower is good coal 3 



3. Upper part fire clay, in middle are buff nodules of arenaceous limestone 16
