Snow Fork is the most eastern tributary of Monday Creek. Rising east 
of Straitsville it flows south, near the east line of Ward township of 
Hocking county, and bends westward to meet Monday Creek a little 
below Bessemer. The Nelsonville seam is to be seen at intervals along 
this stream and on its western tributaries. By these tributaries a vast 
body of coal is made accessible.. The coal can be mined up the dip, and 
easy drainage secured. Ward township contains so much coal that the 
existence of it on any farm gives the farm no distinction whatever. The 
Nelsonville seam extends as a continuous sheet of coal through the whole 
township, varying in thickness from six to eleven feet. There are local. 
ities where the coal has been made thin, or been’ entirely removed by 
eroding agencies exerted during the deposition of the Coal Measures; but 
the limits of these can only be ascertained by practical tests. There are 
places along Snow Fork where I am led to think the coal is too thin to 
be of any value. Wesee the intrusive sand-rock at some points usurp- 
ing the place of the coal. Asa general rule—but a rule to which I have 
in my observations found many exceptions—the quality of the coal 
under an immediate sand-rock cover is much more likely to be contam- 
inated with bi-sulphide of iron. This was seen to be the case at some 
points on Snow Fork. |
