On the face of Mt Joli among the vertical strata we believe it 

 probable that a displacement has taken place by a downthrow which 

 has squeezed out the rocks represented by the fauna found in the 

 beds at the Limekiln. This is inferred wholly from the nature of the 

 fossils of the latter. Their place is here in the succession of the faunas, 

 but should subsequent developments tend to show that the fossils 

 there found were derived from another source, either from the rocks 

 of Cap Blanc or the limestones northward toward the Barachois, we 

 need not open the cliff to admit this mass. On the other hand, were 

 such the evidence, it would seem to be the remnant infaulted by a 

 displacement whose zone rests where now is the short beach between 

 Joli and Cap Canon. 



The displacement we have already noted in the south flank of Mt 

 Joli and shown in the rock wall is within the succession of lower 

 Siluric faunas, these fossils occurring on both sides, and we hence 

 infer it not to have been of great depth. 



On the i\Iurailles we find the clearly defined line of displacement 

 along which the Perce beds have slipped down over the Barre beds 

 inverting -their dip, and this entire mass of Barre and Perce beds 

 was evidently cut off by the longer line of faulting from the Perce 

 rock. These lines of probable displacement of the limestone masses 

 we have expressed on the map adjoining. 



Surface conditions preceding deposition of red sandstone and con- 

 glomerates. Strip off the mantle of red, almost horizontal conglom- 

 erate through which the limestone cliffs project their heads and the 

 country would present an irregular series of jagged limestone bluffs, 

 the remnants of broken and eroded folds, which the tooth of sub- 

 aerial weathering, of stream erosion and the endless gnawing of the 

 ocean, left standing. The vertical position of most of those once 

 horizontal rocks is in itself an indication of the immense proportions 

 attained by the primary folding of the strata. The presence of an 

 anticline at Perce was recognized by Logan, and without venturing 

 to go so far afield as to connect the structures here with those beyond 

 the scope of this sketch, it may be said that the simplest explanation 

 of the relation of the Perce limestones with the series as exhibited 

 from Little Gaspe to Shiphead is a great syncline beneath the sea, of
