More especially the thick limestones of the latter dis- tricts are not represented, and there is a greater prevalence of sandy and argillaceous deposits, often with fossil plants. Minor differences exist in the Acadian Provinces themselves. In Nova Scotia only the lower members of the system have been distinctly recognised, though there are indications of the upper members. In New Brunswick the newer portion of the Devonian seems most largely developed, and is remarkably rich in fossil plants. I shall first notice the Lower Devonian rocks of Nictaux and its vicinity in Western Nova Scotia, and then, crossing the Bay of Fundy, describe the rich plant-bearing beds iu the vicinity of St John, New Brunswick. Devonian of Nova Scotia. In Nova Scotia the rocks older than the Carboniferous system have all undergone more or less and disturbance. This, with the imperfect preservation of their fossils and their inland position, renders the working up of their details of stnicture very difficult. Large tracts of country thus remain in a state of uncertainty, their rocks being manifestly older than the Carboniferous, but yet otherwise of uncertain age. In the case of the Devonian, the only place in which it has been clearly made out as distinct from the Silurian, is the belt of hilly country extending along the south side of the Annapolis valley. Here, in the section of the Nictaux River, the first old rocks *hat are seen to emerge from beneath the New lied Sandstone of tlie low country, are fine-grained slates, which I shall describe in the sequel as Upper Silurian. Their strike is N. 30° to 60° E., and their dip to the S. E. at an angle of 72Â
