6. Arenaceous shale. — Brick-like 

 in texture, varies in colour from 

 yellow to purple. Carries fossils 

 of gastropods, brachiopods, co- 

 rals, etc 10 inches, 25 cm. 



7. Calcareous shale. — Yellow, 

 brick-like, showing in some loca- 

 lities fossils, generally as casts 



or moulds 60 inches, 1 52 cm. 



8. Calcareous shale. — An irregular 

 bed, weathering readily to a no- 

 dular mass, although in some 

 places more compact. Few fos- 



sils. 



.36 inches, 91 cm. 



9. Calcareous shale. — Yellow, brick- 

 like, very much like No. 7. Con- 

 tains fossils, corals, bryozoans, 

 brachiopods, gastropods, etc. ,...66 inches, 168 cm. 



10 Shale. — Red, loose in texture, 

 weathering readily to a crumbling 

 mass. Interlaminated with lime- 

 stone beds about 2 inches in 

 C < thickness. Both limestone and 

 shale are quite fossiliferous, bea- 

 ring corals, bryozoa, brachio- 

 pods, gastropods, cephalopods, 

 ostracods, and trilobites 144 inches, 366 cm. 



The beds exposed in this section are believed to repre- 

 sent the Richmond and possibly the Lorraine formations 

 of the Ohio Valley. Good sections of the lowest shale 

 of the above section can be obtained in abundance. 



This lowest shale is the best of the series for the 

 collection of fossils, and is exposed at several places over 

 the mountain. One of these is to the south of the Winnipeg 

 city quarry, and just below the Manitoba quarry, near 

 their old lime kiln. Two other exposures are on the 

 prison reserve: one in the prison gravel pits in the face 

 of the hill opposite the main buildings; the other a short 

 distance to the southeast of this and in the same face of the 

 same hill.
