elevation subjected to movements and warping given the Carboniferous its present undulations, thus I Mt. St Anne in Bonaventure and as its elevation is about 1200 feet one realizes not only the minimum amount of elevation but also the great thickness of this Carboniferous employed. Another fact impresses one and that is that (all Cape Cormon) all the Ordovician we see here are then folded light blue (weather may whiten much more). limestones of great thickness in the aggregate. On the other side of the Basque Peninsula the Ordo- vician beds are all floccy shales. Is it possible that these two areas were separated by a barrier in which has laid down the Lewis shales and in the other the Atlantic type of Ordovician limestones and limestones, In the one nearly all muds with a proftilic fauna in the other nearly all limestones with a sparing fauna.
