CHAPTER XVI. 
THE COAL SEAMS OF THE LOWER COAL MEASURES 
OF OHIO—ContTINUED. 
Tuer Hockine VALLEY CoAL FIELD. 
By EpWARD ORTON. 
The Hocking Valley coal field will be considered in this chapter 
as comprising those portions of Perry, Hocking and Athens counties 
in which the Middle Kittanning coal (Coal No. 6, of Newberry) reaches 
or exceeds 5 feet in thickness. Almost all of this territory is included 
within the drainage limits of the Hocking river, and this fact deter- — 
mines the name by which the field is known. For the sake of con- 
venience, a few small districts will be described in this chapter in which 
the coal of the Middle Kittanning seam falls below 5 feet. These 
districts embrace portions of York and Waterloo townships, Athens 
county, and portions of Starr and Washington townships, Hocking 
county. 
The field, as thus qualified, embraces the southern part of Monday 
Creek township, the south-eastern half of Salt Lick, the southernmost 
sections of Pleasant and Coal and Monroe townships, in Perry county ; 
in Hocking county, Ward, Green and Starr townships, with asmall and 
unimportant outlier in Washington township; in Athens county, 
Trimble, Dover, York and Waterloo townships. 
Some general statements as to the character and structure of this 
field are given in Chapter I, pages 102—117. 
The Hocking Valley produced in 1883, 3,270,000 tons of coal, or 
about 2 of the total production of Ohio. This statement shows that it 
far transcends in present importance any other single coal field of the 
State, being fairly comparable with all the rest combined.
