In this paper, the author, after a general description of the geological character of the country, describes the superficial deposits which he divides into—

1. The unstratified drift or boulder formation. This, the lower of the two superficial deposits, is characterised by the circumstance, that most of the materials have been derived from the rocks on which they now rest, or those in the vicinity. The fragments are angular, and altogether devoid of any regular arrangement. This unstratified drift, however, does contain boulders from distant localities, which may generally be traced. The appearances indicate that the materials have been transported from the northward, and also, to a less extent, from the southward, and, indeed, in various directions.
