REPORT OF PROGRE8S. E. W. CLAYPOLE. 



of Limestone ridge where the road passes through or rather 

 over the Hamilton sandstone. The channel of the brook 

 can scarcely be called a gap, rising as it does to summit 

 level where the water, before it begins its journey down the 

 hill, is employed in washing the ore. 





The Hamilton fossil ore. 



This belt of iron ore runs through the township immedi- 

 ately north of the Hamilton sandstone but I am not aware 

 that any has ever been taken out along its line of outcrop, 

 which is very near the edge of the woods for the most part 

 though in some places toward the eastern end it lies w r ell 

 up in the wood. Its place may be found on the map by 

 marking the top of the Hamilton sandstone. 



Several attempts have been made to open the bed but 

 little more has been done than to prove its presence along 

 the north side of the hill. It is certainly very thin in most 

 places and the probability is that if opened it would prove 

 lean and sandy. 



The Hamilton Upper shale. 



This band of shale crosses the township parallel to the 

 Hamilton sandstone. It crops out in the side of the road 

 leading from Newport to Duncannon, about one hundred 

 yards south of Mr. Harness house, and zigzagging like the 

 sandstone crosses the township line in the fields east of the 

 lower end of the narrows. It may be seen in Centre town- 

 ship on the Newport-New Bloomfield road near the top of 

 the hill rising from Inoculate run where it is very calca- 

 reous. The characteristic fossils of the Fenestella shale 

 may be found abundantly at both these outcrops. 



The Genessee shale, (VIII.) 



The w 2<><) feet of barren, whitening shale which I have con- 

 sidered t<> represent the Gtenessee of New York may be 

 found in their proper place between the Hamilton Upper 

 shale and the Portage shale. They crop out ;it the road- 

 side immediately over the Hamilton Upper shale.
