COAL MINES OF LAWRENCE COUNTY. 1043 
At Washington Furnace many small banks have been worked in 
the seam. Itshows here the structure represented in the following figure, 
which represents its normal composition of this region:

Its quality is fair, as has been before stated. Itis rather high in 
sulphur and also in ash, but it burns readily and lasts well in the fire. 
It is valued for steam generation wherever it is used. 
At Lawrence Furnace, Section 4, Elizabeth township, the seam has 
in like manner been long mined in a small way. Throughout this 
township and also to the southward and eastward, a massive sandstone 
separates the Kittanning coals, often coming down directly upon the 
lower seam. ‘This is shown in the following figures:

It will be seen that the upper bench is reduced from the measure 
previously shown by the deseent of the sandstone, and that the thick- 
ness of the coal is thus brought below fairly mineable proportions.
