IRON ORES OF THE CLINTON FORMATION 57 



between the Lehigh Valley and New York Central (R. W. & O. 

 branch) railroad lines. The company was organized in 1906. The 

 work done thus far consists in the opening of a trench which begins 

 about 400 yards southwest of the station, near the railroad track, 

 and follows the line of outcrop to the east. The bed is found here 

 beneath 10 to 25 feet of soil and rock. The loose overburden 

 represented by soil and glacial materials varies from 18 inches to 

 10 feet. A general section involving the ore, made some distance 

 back from the outcrop, with a maximum of covering, is as follows:

Soil 10 



Shale 55 



Limestonie i . 5 to 2 



Ore. ■ 3 



Green shaly limestone 5 



Medina 10+ 



The ore as shown in the trench ranges from 30 to 38 inches thick, 

 the average mineable thickness being probably about 30 inches. 

 There is generally a seam of limestone i or 2 inches thick in the 

 middle of the ore, while the limestone covering the ore is from 10 

 to 18 inches thick. Eight feet above the main bed is a thin seam of 

 ore, reaching 4 inches as a maximum. The shale above the ore 

 bed is at times quite compact, but presents no difficulty to excava- 

 tion after loosening by blasting. It carries one or more layers of 

 Hmestone which appear at different horizons and are not persistent 

 for any distance, their total thickness amounting to 5 or 6 inches.
