 yards (91-5 m.) along the hill-slope above the sandstone 

 quarry. The section at this point is as follows : 



Onondaga limestone. F^et" Metres. 



4-Cherts and cherty grey limestone 

 weathering out over the hill side. The up- 

 per part contains an abundance of corals 

 chiefly of the compound type 15 4-575 



3-Arenaceous cherts weathering out in 

 the field _ -5 -153 



2-Arenaceous grey limestone which be-

Springvale sandstone.

Section at the Teitz quarry. — On the Teitz farm, 

 about two and a half miles (4 km.) west of Springvale, 

 quarrying operations have revealed a ridge of limestone 

 which lies under a very thin covering of drift. Although 

 the thickness of rock exposed here is slight, the bottom 

 layers extend downwards to about the horizon of the top 

 of the section on Mr. John Winger's place and thus form 

 almost a continuation of that section. The section is 

 as follows :

 Feet Metres. 



4 — Weathered, cherty limestone which 

 may have been slighly moved -5 -153 



3 — A semi-crystalline, grey limestone 

 filled with the smooth variety of Snathophyl- 

 Inm simcoense (Billings), and having a few 

 thin layers of chert in it 3-5 1 • 068 



2 — Semi-crystalline, grey limestone al- 

 ternating with beds of soft, shaly, bluish-grey 

 limestone. The semi-crystalline layers are 

 usually very crinoidal and contain a good
