This section is interesting in that it is one of the few obtained in this 

 county presenting all the peculiar features of this bed as observed in 

 other counties. The little "bearing-in bench," No. 7, is not ordinarily- 

 distinguishable in Jefferson county, though very characteristic elsewhere. 

 At this opening, the pyrites band is quite persistent at from two to eight 

 inches below the clay, and No. 10 is not infrequently composed of pyrites, 

 in which case it is somewhat thicker than is given above. Nodules of 

 pyrites are common in Nos. 3 and 11, and cannot always be separated 

 easily. Horsebacks of fire-clay frequently come up from below, and some- 

 times cut out No. 11 wholly. The main clay parting, No. 2, thickens at 

 the expense of No. 3, and sometimes contains streaks of coal. This bank 

 is an important one, and is worked extensively to supply the neighbor- 

 hood for several miles around. On Mcln^yre's Creek, near the southern 

 line of the township, this coal is mined by Mr. Amos Hoagland, where 

 the bed is — 



1. Eoof coal 1 foot to 1 foot 6 inches. 



2. Clay 6 to 10 inches. 



3. Coal , ■ 4 feet 6 inches. 



The coal is of good quality, but the "brick coal" contains many len- 

 ticular nodules of pyrites, some of them quite large. The pyrites band 

 in the upper portion is not persistent, but a similar one, one-half inch 

 thick, is constant at from eight to ten inches from the bottom. Along 

 the line of the P. C. & St. L. Railway, this coal lies about three hundred 

 feet above the track. The sharpness of the hills renders the work of 

 constructing roads quite difficult, and no openings seem to have been 

 made. 



The limestone, thirty-five feet below the coal, is somewhat fossiliferous, 

 and portions of it are crowded with minute univalves. It is sufficiently 

 pure to be burned, and yields a good lime, even under careless treatment. 

 The Crinoidal Limestone was seen only at one locality, and that almost 

 directly on the eastern line. It is about two hundred and fifteen feet 

 below Coal No. 8, and is gray and compact. It is too impure to yield lime. 

 At nearly three hundred feet below Goal No. 8, blossom of coal was seen 

 at two localities. 



Steubenville Township. — Here, as in Cross Creek, Coal No. 8 is found only 

 in the highest hills. These are quite abrupt, and the coal is difficult of
