One whole pciiod of the earth's Pala?ozoic appears to be represented by no monuments in Acadia. Ulie base of the Trias cverywlicre rests uncoiifoniiably on the ui)turned licdsof tlie ("arboni- ferous, and the Pcrinian , represented in Knj^daud by the great mi;giiG:*Ian limestone and its associated beds, and in Ciermauy by the Zeehstein and the sandstones and sliales above nnd below it, is absent from our series of formations. The same gap occurs, in so far as known, throughout Eastern North America. It is only west of the Mississippi, in Kansas, and on the eastern slope of the Kocky Moun- tains, that the Permian beds have been recognised. There tiicy consist of limestones, sandstones, marls, and conglomerates, with beds of gyj)suni resting Cduforinably on the (.'arboniferous beds, and separating them from the Trias. Their fossils are closely allied to those of the Upper Coal Eormation, and very diiVerent from those of the Trias,âthe latter constituting the begiuning df the great Mrsozoic division of geological time, the former the close of the J'akrozuic. The lapse of time represented by these Permian beds, and which, though j)robably shoi'ter than the Carboniferous period, must have been of lung duration, is indicated in Acadia oidy l)y the disturbances wliich the Carboniferous beds have sufTcrcd before the deposition of those of the Trias, unless wc can regard any portion of the great series of beds which I have named the Upper Coal Formation as equivalent in time to the Permian. It may be well shortly to iiujuirc if we can bridge over this vacant space by any considerations based on the well-known systems of formations which constitute its bouiularies. We have
