THE LOWER COAL MEASURES. 193 
The analysis of the Leetonia coal and coke has been already given, 
and can be compared with these results. 
The Clarion coal, as shown in No. 3, appears to unusual advantage. 
Aside from the high percentage of sulphur, it would seem to be a first 
class coal, but the analysis is too favorable, being probably made from 
selected samples. 
The line of facts brought to light by the several well records at 
Leetonia will be borne in mind in this connection (see pages 35 and 36). 
The Leetonia field includes the New Albany coal of Green town- 
ship, Mahoning county, where the seam reaches its best development. 
It has long been worked here for the supply of the adjoining county, 
and especially for the town of Salem. 
In the southern portion of Salem township, and also in Centre 
township, we find the Freeport coals and also the Brush Creek coal 
coming into the section. The Upper Freeport coal gave a flattering 
promise on the Shelton and Arter farms, and was opened there a number 
of years ago with great expectations. The coal was 7 feet thick on the 
outcrop, but it soon ran down to 3 feet, and was left at 23 feet a short 
distance under the hill. It averages about 4 feet in the neighborhood, 
and is still worked, though not in large mines. The Brush Creek coal 
on the Arter farm is found 38 feet above the Upper Freeport, but a 
short distance below a seam is opened only 12 to 15 feet above the Big 
Vein. Whether this is the Brush Creek coal or one of the irregular 
beds that sometimes occur at the Upper Freeport horizon, cannot be 
decided here. The series shown in this immediate vicinity is as follows:

The other elements that are due, and especially the limestones, all 
come in their places with regularity. The Upper Freeport or White 
limestone, as it is here designated, is a constant and conspicuous stratum. 
The Lower Freeport limestone is mined on a large scale in this imme-
