 bedded, grey, micaceous shales of the Lorraine are exposed, 

 with much the same strike and dip as the Quebec City 

 formation. Up the hill, above the shales, the harder shales

exposed in trenching for city improvements, and the indi- 

 cations are that the Quebec City is thrust over the Lorraine, 

 instead of the two lying side by side, as in a normal fault. 

 The Lorraine here has afforded numerous specimens 

 of Diplograptus pristis and small brachiopods of the genus 

 Dalmanella. 



Continuing along Arago street the bluff may be climbed 

 at Cote Sauvageau, where the soft shale is in marked 

 contrast to the hard limestone and shales seen at Cote a 

 Cotton and Cote d'Abraham. 



After climbing Cote Sauvageau to the point of inter- 

 section with Reservoir hill, by descending that hill 200 feet 

 (60 m.), the thin-bedded, soft, grey micaceous Lorraine 

 shales will be encountered. Certain layers in this shale 

 contain a great abundance of graptolites.
