summits, but it is generally thin. Below this, Coal No. 5 is either want- 
ing or too thin to be workable; still lower, and generally near the level 
of the valleys, is Coal No. 4, which is sometimes cannel, sometimes part 
cannel and part cubical coal, and in still other localities, as at Leetonia, 
Washing‘onville, etc., is a thin but very pure bituminous coal. 
At Unity coal has been struck in a well near the saw-mill, sixty-two 
feet below the surface at Unity Center, which is about two hundred feet 
above Palestine. No facts were furnished which would serve for the 
ident fication of the coal. In section 16, Unity township, at Davis’s 
Mine, coal is worked sixty feet below the surface. It is about five feet in 
thickne-s, in two benches, the upper two feet three inches, cannel, the 
lower two feet nine inches, bituminous. From its altitude, this coal was 
supposed to belong toa diff r-nt seam from the cannel so generally worked 
in the southern townships of Mahoning county, but from the character 
of the coxl this would seem to be the mest natural inference. 
At L«etonia Coal No. 4 is quite l.rgely mined, and forms the basis of< 
an extensive iron industry in this locality. It is only from twenty- 
eight to thirty inches in thickness, but is remarkably pure, and makes 
a coke of superior quality. 
At the coal works of the Cherry Valley Tron Company, at Leetonia, 
the coal is mined by a slope, at the depth of seventy feet from the sur- 
face. Itishere twenty-eight inches in thickness, in two benches, the upper 
one eight inches thick, the lower one twenty. It is overlain by black 
and gray shale which contains a notable quantity of iron, as is usually 
the case at this horizon. One mile east of Leetonia, on the Pittsburgh, 
Fort Wayne and Chicago Railroad, a new mine has just been opened on 
Coal No..4 by Messrs. Delo, Van Fieet & Co., in which the coal appears 
to be of very good quality. It is thiity-three inches in thickness, with 
three inches of cannel on the top, and this overlain by the usual heavy 
iron shale. 
At the nail factory at Leetonia a well has been bored, nominally for 
water, but possibly for gas, or with a view to reach Coal No. 1. A care- 
ful record is being kept of this boring, which, it is said, will be carried 
down several hundred feet The results of this experiment may be of 
great importance to the localities where it is made. 
At Washingtonville Coal No. 4 lies twenty feet higher than at Lee- 
tonia. Its associated strata are:
