to the cutting on the road, conglomerate A will be seen 

 in place below conglomerate B. The cutting on this 

 road gives an excellent opportunity to study the conglo- 

 merate in detail. Many of the pebbles are large, sometimes 

 more than a foot in diameter, usually more or less rectan- 

 gular and not well rounded. The interstices between the 

 larger pebbles, are filled with smaller pebbles, and there 

 is very little paste. Most of the pebbles are of limestone, 

 and many of them are fossiliferous. The fossils obtained 

 here were chiefly of Beekmantown age. Some of the 

 pebbles are themselves derived from a conglomerate, 

 and others are composed of an oolitic limestone. Besides 

 the limestone, pebbles of gneiss, quartzite, sandstone, 

 and shale may be seen in this exposure. 



LEVIS TO MONTMORENCY FALLS. 



An excellent view of Quebec may be had from the ferry 

 while crossing from Levis to Quebec. On the highest point 

 is the Citadel, while about half way down the cliff is the 

 Dufferin terrace and the Chateau Frontenac. The rocks 

 which form the cliff are limestones and hard shales of the 

 Quebec City formation (Middle Trenton). 



After leaving the Quebec Ry. Light and Power Co. railway 

 station, the St. Charles river is soon crossed by the electric 

 tramway and the route proceeds along the low land near 

 the shore until Beauport is reached. 



At Beauport (2.8 miles, or 4.5 km.) a quarry in the 

 Trenton limestone shows the strata to be thin-bedded, 

 pure, blue-black limestone with thin shaly partings 

 belonging to the middle division of the Trenton. Immed- 

 iately beyond this quarry the train leaves the main line 

 of the railroad and begins to mount the terrace. On 

 this rather steep slope a cut has been made, exposing the 

 Utica shale. This shale has a steep dip toward the river, 

 whereas the Trenton strata in the quarry are horizontal. 

 A fault which will be observed at Montmorency, passes 

 between this cut and the quarry. Reaching the edge of 

 the terrace, the railroad crosses the sloping top until it 

 approaches the Beauport-Montmorency highway, which 

 it parallels for the remainder of the distance. Numerous 

 small quarries and lime kilns to the north of the railroad, 

 show the presence of the Trenton limestone along the 

 highway, the railroad itself remains upon the Utica and
