Mr. Jukes-Browne, F.R.S., in a paper entitled “The Making of Torbay”, which has recently appeared in the Trans. Devon Assoc. for 1912, incidentally refers to the Raised Beaches of Torbay as follows: “The age of these beaches has been fairly well settled by the determination of the date of similar beaches in South Wales … the beaches testify to a subsidence which culminated either just before or during the epoch of maximum glaciation” (Trans. Devon Assoc. 1912, p. 726).

During a short holiday to North Wales in Whit-week, 1910, I was investigating the igneous rocks to the south of Llanfairfechan, more particularly the intrusive greenstones of the Geological Survey map. Since the publication of this map, over fifty years ago, several districts within it have been investigated in greater detail, especially as to the volcanic rocks, but much remains to be done petrographically. One of these greenstones turned out to be of exceptional interest, being of a type of rock hitherto, I believe, unrecorded in North Wales, so another visit was made to it in August, 1912.

The Dane Hill Sandstone Group, as we propose to distinguish the higher of the two series of Upper Keuper sandstones, since it is well developed in the neighbourhood of the Dane Hills at Leicester, is well exposed in a little quarry at Ashleigh House. Here the highest part of the series is seen, with thin beds of flaggy marl and calcareous White or Green Marl, overlying a series of thick-bedded, currentbedded sandstones, of white colour, loose and friable, but hardening on exposure. The section has been described by Browne (1893), but at present is exposed to show a better sequence (see next page).
