limestones and Siluric shales but not the Gaspe- 

 Bonaventure conglomerates were upfolded and 

 remained above the reach of the waters during, 

 the deposition of the Gaspe sandstone at the north. 



Then followed at the north the upturning of 

 the successive anticlines in which both Devonic 

 limestones and Gaspe sandstones are together 

 involved, and finally the depression during the 

 Gaspe-Bonaventure stage and overwhelming of 

 the Perce anticline by the encroaching mantle of 

 congrlomerates resultinof from its own ruin. 



The Gaspe syncline, or that portion of the great 

 geosyncline which included Gaspe county, was thus 

 filled up. The last of its plications were the suc- 

 cessive waves which involve the ten thousand feet 

 of Devonic limestones and sandstones at the north, 

 and the final stage of deposition was begun with the 

 quiet submergence of the plicated area at the south 

 and closed by its reelevation into a plateau mantled 

 with the gently dipping beds of conglomerate. 



It has been the observation of some writers, 

 Suess especially, that meridional mountain sys- 

 tems are generally attended by areas of independ- 

 ent fiexure, gentle in degree, such as are indicated 

 by the so called Cincinnati dome and like areas 

 west of the Urals. To these the author cited 

 has applied the term parma. We may here direct 

 attention to the areas of early middle and late 

 Siluric rocks whose exposures are now to be seen 

 in the region north of the Gaspe geosyncline, in 

 the Island of Anticosti, the Mingan islands, along 

 the straits of Belle Isle on the Labrador and across
