The calcareous shale at the top lies in numerous definite layers 
and contains considerable alumina. It lifts readily in thin layers 
at the thin clayey partings. The clay parting between this shale 
and the limestone proper leads one to identify it at once with the 
2 inch parting in the quarry at the cement works. The worth- 
less shale here above the clay parting becomes an impure lime- 
stone at the cement works. The limestone has a light blue color 
and the coal beneath is said to be 14 inches thick. The Limestone 
lies at about 1 120 feet above sea and is undoubtedly the Putnam 
Hill. 
Mr. D. L. Worstler in 1907 opened a quarry to burn lime on 
the farm of B. F. Werner 1 mile southwest of Middle Branch and 
1 mile northwest from the Worstler quarry. The elevation is 
about 1 130 above sea. No shale layer or clay parting occurs here 
as drift lies directly upon firm rock. The following section indi- 
cates the nature of the stratum in this quarry.

The upper part of the stratum of limestone has doubtless been 
eroded as the top layer shows abrasion. No. 4 is more compact 
than No. 5 which is in accord with the middle layers at the 
Cement Plant. 
No. 3 is black and porous, and not so compact as No. 4. 
The pores are filled with oil which soon greases a freshly broken 
face and yields the characteristic odor. The coal is ample for 
burning the lime and runs from 24 to 28 inches in thickness. At 
a farm house about 350 yards west of this pit a limestone was 
penetrated in a well at about 35 or 40 feet above the quarry stone. 
These limestones are clearly those at the Cement Works. 
Dip of the Strata in the Nimishillen Valley. 
It readily appears from the elevations of the limestones at the 
various outcrops that there is a dip of the strata toward the 
south. Placing the elevations together of any one stratum from
