anticline lies at the bend in the road and the beds encount- 

 ered below are a repetition of those above. The thick 

 beds of grey limestone at the foot of the elevator should 

 be noted and compared with those exposed in the cutting 

 at the top of the hill. 



From the foot of Cote du passage and Davidson street, 

 northeastward along Main street, two bands of the thin- 

 bedded Shumardia limestone can be seen extending along 

 the face of the bluff to the wooden steps. Here the 

 limestones disappear below the street level, and the axis 

 of the anticline passes to the river side of the road. Between 

 the next two buildings on the southeast, 500 feet (150 m.) 

 east of the steps a fault brings conglomerate A down nearly 

 to the bottom of the cliff, and conglomerate B to the top of 

 the bluff face. 



The B conglomerate here is mostly thin-bedded lime- 

 stone, with a little conglomerate at top and bottom. At 

 the small point just beyond these two houses another fault 

 brings conglomerate A down to the foot of the cliff, and 

 B down against A. Immediately on the point are two 

 other minor slips. 



Beyond this point, are the best exposures in the vicinity 

 of Levis. Conglomerate A, which is 15 feet (4-5 m.) 

 thick at the point where the faults occur, can be traced 

 past the lime kiln at the foot of the bluff, up into the bluff 

 face, where it dwindles to a mere two-foot bed. Above 

 it is a conspicuous layer of thin-bedded limestone, and still 

 higher the thin-bedded limestone of conglomerate B. 

 The latter bed is here quite fossiliferous and contains 

 Phyllograptus anna, Dictyonema, Shumardia granulosa 

 Lingula quebecensis and other fossils. In the middle 

 of the cliff, below conglomerate A. is more thin-bedded 

 limestone and the fossils prove it to be the Shumardia 

 limestone, here freed from the effect of the anticline and 

 without the thick beds of grey limestone that are above 

 it on Davidson street. Ten feet below this limestone 

 is a hard grey shale with Dawsonia, Phyllograptus, Dicho- 

 graptus, and brachiopods. 



By following the first street leading southward from 

 Main street at the top of the hill, conglomerate B may be 

 seen in more detail. At first sight this appears to be 

 conglomerate A, but by following it along the surface, 

 with almost every foot exposed, it is seen to run into 

 a thin-bedded limestone at the top of the bluff. Returning
