with it. The fauna, however, is Onondaga (10) in every 

 characteristic and cannot be confused. But, because 

 of the decided lithological difference from the ordinary 

 appearance of the formation to which they belong, the 

 beds are here referred to as the Springvale sandstone. 

 This sandstone has a thickness of about 8 feet (2-44 m.) 

 and the material of which it is composed was doubtless 

 derived from the Oriskany sandstone, portions of which 

 were re-worked by the advancing Onondaga sea. The 

 Springvale sandstone is succeeded by cherty grey and 

 bluish limestones attaining a thickness of over 60 feet 

 (18-3 m.) in the vicinity of Hagersville. This mass is 

 all rather fossiliferous : at some horizons the remains of 

 corals especially occur in great abundance. 



ONEIDA QUARRIES. 



Five and three quarter miles (9-2 km.) southeast of 

 Hagersville, on Lot 49, Concession 1 of Oneida township 

 in Haldimand county, the Oneida Lime Company has sev- 

 eral interesting quarries. At several places along the 

 roadway from Hagersville (old Indian line) the cherty 

 layers of Onondaga limestone come to the very surface. 

 At Gill, 3-75 miles (6-04 km.) southeast of Hagersville 

 the road turns east at the brink of one of the terrace-like 

 outcrops of Onondaga limestone above mentioned. 



On the southern part of Lot 50, Concession I of North 

 Cayuga, the Oriskany sandstone comes to the surface 

 and has been quarried on a limited scale. 1 ue uneven 

 contact with the Silurian may be seen here while the surface 

 of the sandstone shows the effects of glaciation. The rock 

 is abundantly fossiliferous and, near the old barn at this 

 point, its surface is literally paved with Stropheodonta 

 magnified Hall. If this ledge of sandstone is followed 

 eastwards into the woods, other excellent outcrops will 

 be found and also a greater variety of fossils. 



At the cross-roads, a short distance to the east, are 

 the quarries and plant of the Oneida Lime (and S? ^d) 

 Company. Here a greater thickness of the sandstone may 

 be observed as well as a small quarry in the Silurian lime- 

 stone.
