862 GEOLOGY OF CHIO. 
Creek township, Perry county. The place of this ore is about thirty-five 
feet below the Nelsonville seam of coal. This brings it below the Lower 
Lexington coal, or Coal No. 5 of the northern series. In the vicinity of 
the Baird Furnace this lower coal is often seen, especially on the ridge 
between the furnace and Maxville. The ore is here about ten feet below 
the latter coal and at the bottom of the light colored fire clay. Sometimes 
there 1s under the ore a thin layer of fossiliferous limestone, but this is 
often wanting, and sometimes it is changed into flint. The ore in this 
region is generally oxydized on the outcrop, but, under deep and im- 
pervious cover, it retains its original quality of a carbonate. The thick: 
ness of the layer is from eight to ten inches, but it is often thinner in 
its outer margin, where the ore is decomposed and crumbling. Before 
the erection of the Baird Furnace, ores from this neighborhood had been 
taken te the Logan Charcoal Furnace and used with entire success. 
I have seen but a single analysis of the ore, from this region. It was 
such as was used in the Thomas Furnace, at Gore. It was given me by 
Gen. Thomas and has already been published by Mr. E.C. Pechin in the 
Metallurgical Review.

LT have no doubt that much of the Baird ore is better than this. North- 
east of the Baird Furnace on the land of Jacob Martzoff, in Monday Creek 
township, I found in the road an ore resting on flint which I took to be 
the continuation of the Baird seam. It is one foot thick and thirty-eight 
feet below a seam of coal supposed to be the Nelsonville seam, and also 
below'Coal No.5. It is a very superior ore as shown by the following 
analysis by Pref. Wormley:
