shrine of Ste Anne. Looking from the higher summits of the Forillon, the 

 Perce Rock slips above the horizon and from Shiphead Hght at the tip of 

 the Cape one sees Bonaventure island stretched out full length ; beyond 

 them all the great expanse of gulf waters. 



Gaspe limestones of Logan 



Sir William's subdivision of the limestone series which has its base at 

 Cape Rosier Cove on the north and whose uppermost beds skirt the coast 

 of the Forillon from Little Gaspe to Shiphead, is here given in full in 

 ascending order as presented in his Geology of Canada [1863, p. 391].

1 Gray limestones in layers of from six to eight inches thick, which are separated 



by bands of greenish calcareo-argillaceous shale, gradually increasing in 

 amount towards the upper part. The limestone beds abound with fossils, and 

 contain, among other species, large crinoidal columns, Favosites gothlandica, 

 F. basaltica, F. cervicornis, with undetermined species of Zaphrentis, Dictyo- 

 nema and Fenestella, two undetermined species each of I-ucina and Stropho- 

 mena, with S. rhomboidalis, S. punctulifera, two or three undetermined species 

 of Orthis, Rhynchonella acutiplicata, two or three species of Orthis, Penta- 

 merus galeatus, three undetermined species of Spirifera, Athyris laevis, Atrypa 

 reticularis, Cyrtodonta orbicularis, C. lata, C. flexuosa, Modiolopsis cultrata, 

 Avicula bronni, A. naviformis, Loxonema gaspensis, L. gracilis, Bellerophon 

 laurenticus, two undetermined species of Platyceras, an undetermined Conu- 

 laria, with several undetermined species of Orthoceras, Dalmanites pleuroptyx, 

 an undetermined Phacops, Bronteus canadensis, and an undetermined species 

 of Beyrichia ............. 'jo 



2 Greenish calcareo-argillaceous shales, which are interstratified with less calcare- 



ous layers, of various shades of red. The only fossils observed, occur about 

 the middle of the deposit, and consist of jflattened stems of marine plants, 

 apparently replaced by oxid of iron ........ go 



3 Olive-green calcareo-argillaceous shales, with occasional nodules and layers of 



compact limestone ; the former from an inch to a foot in diameter, and the 

 latter from six inches to two feet thick. Some of the layers are rather arena- 

 ceous ; remains of fucoids occur at the top - - - - - - -170 



4 Gray limestones in thin beds, separated by gray calcareous shales, of Avhich there 



are more towards the bottom than the top. The whole mass is interstratified 

 with three or four bands of olive-green calcareo-argillaceous shale. About 

 fifty feet from the bottom, there is a bed of seven feet, made up of several thin 

 layers of limestone and limestone shale, and presenting a singularly wrinkled 

 structure, from which the beds above and below are free. It would appear as 

 if the layers, after their deposit, had been contorted by lateral pressure, the 

 underlying stratum remaining undisturbed, and had then been worn smooth, 

 before the deposition of the next bed. Where the inverted arches of the 

 flexures occur, some of the lower layers are occasionally wanting ; as if the 

 corrugated bed had been worn on the under as well as the upper side. The 

 corrugations are precisely in the direction of the dip, and the peculiarity is
