THE CARBONIFEROUS SYSTEM. 135 
From these facts it is apparent that Coal No. 1 does not form a contin- 
uous. sheet in the central part of the coal basin, but that it underlies a 
considerable portion of the area east of Massillon and south of Youngs- 
town is almost certain. True caution should, however, be observed in 
making expensive explorations for this coal. It is proverbially irregu- 
lar and patchy, even where best developed, along its outcrop, and borings 
for it, therefore, are always uncertain. 
One or two shafts sunk to the coal, some distance from its line of out- 
crop, and opening up prosperous mining enterprises, will stimulate in- 
vestigation, and lead ultimately to the thorough exploration of the area 
of this coal.

Coat No. 2. 
Coai seam No. 2 lies from 40 to 100 feet above No. 1. This difference 
is occasioned by inequalities in the lower coal, which was evidently more 
or less folded and disturbed previous to the deposition of the second seam. 
Usually this is a thin coal, and one that has no economic importance, but 
it is an almost constant feature in the sections of the rocks of the north- 
ern portion of the coal field, and in a few localities becomes of practical 
value.
