Qiirhr a,uJ its Virimf//.— The deposits at ]5eauport, near 



(.>uebec, were described l)y Sir C. Lyell in the Geological 



Transactions for l.s;!9 ; and a list of their fossils was given, 



and was compared with those of Montreal in my paper of 



1859. As exposed at the IJeauport .Alills, the I'leistoccne 

 beds consist of a thick bed of boulder-clay, on which rests 

 a thin layer of sand with Mhijnrom'Ila ^mttacea and other 

 deep-water shells. Over this is a thick bed of stratified 

 sand and gravel filled with Saxicam rugosa and TdUna. 

 Scattered Laurentian boulders here, as at Montreal and 

 elsewhere, occur in the beds with the shells. In a brook 

 near this place, and also in the rising ground behind Point 

 Levis, the deep-water bed attains to greater thickness, but 

 does not assume the aspect of a true Leda clay. Above 

 (,)uebec, however, the clays assume more importance ; and 

 between that place and Montreal are spread over all the 

 l<.w country, often attaining a great thickness, and not 

 unfrecpiently capped with Saxicava sand. At Cap a la 

 Koche the officers of the (leological Survey have found a 

 bed of stratified sand under the Leda clay. The Beauport 

 deposit is evidently somewhat exceptional in its want of 

 Leda clay, and this I suppose may have been owing to the 

 powerful currents of water which have swept around Cape 

 Diamond at the time of the elevation of the land out of
