feet, and at Malvern it is about the same. At these localities it affords a 

 readily burning coal, which is very sulphurous. 



In Rose township it was at one time mined by the Trumbull Com- 

 pany, on whose property, near Magnolia, it is three and one-half feet 

 thick. It is now worked at a locality about two miles south-east from 

 that village, showing about three and one-half feet of very fair coal. It 

 is interesting chiefly because it overlies the compact fire-clay so exten- 

 sively used at Mineral Point and other localities along the Tuscarawas 

 Branch of the Cleveland and Pittsburgh Railroad. The only locality in 

 Rose township where this was taken out, where these examinations were 

 made, was on the farm of Mr. Wm. Beattie, about one mile south-east 

 from Magnolia. As at that time careful search was making at every 

 exposure of Coal No. 5, it is highly probable that other openings are now 

 in operation. This compact clay is very local in distribution, and deposits 

 are quite uncertain in extent, as the har^ clay often passes abruptly into 

 the plastic variety. On the Beattie farm the clay is compact, on the 

 Trumbull Company's property it is plastic, while on a farm about half a 

 mile west from the last it is again compact. The section exposed on the 

 Beattie farm is as follows :

Coal No. 4 here consists of one foot of alternating shale and coal, rest- 

 ing on two and one-half feet of fair coal. In a well sunk on the other 

 side of the hill it is three and one-half feet thick, and good throughout. 

 The fire-clay. No. 3, is quite dark near the top, but below is beautifully 

 mottled. At the outcrop a layer of large nodules of iron ore and clay, 

 two feet thick, seemed likely to cause much loss, but it ended abruptly 

 at the distance of five feet in the entry. At the time these notes were 

 made the work was going forward energetically, and Mr. Reis, the lessee, 

 had his preparations well advanced for the erection of brick-works on the 

 spot. Fifteen cubic feet of the rock make a ton, and the cost of mining 

 is seventy-five cents. The thin coal below the fire-clay is very poor in 

 quality, and is evidently local, as it was seen at no other exposure. 

 Specimens of this clay were forwarded to Dr. Wormley for analysis, with 

 the following results: 



Water 9.90 



Silica 48.90 



Alumina 39.79
