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 1120 feet above sea and is undoubtedly the Ptitnam 

 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 1130 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 poi'ous, 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 Ninnshillen 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
