In the past there have been two main lines of approach to the glacial problems of East Anglia:—(1) Attempts to find out the number of. glacial and interglacial deposits; and(2) The direction or directions of ice-movement as shown by the constituent materials.A fresh investigation of the boulder clays has been undertaken, combining as far as possible these two points of view, with special attention (so far) to the varieties of “Chalky Boulder Clay” (see Baden-Powell, 1948, pp. 287–8).

Since the Fenland Research Committee was formed in 1932, several papers have appeared, under its auspices, describing recent research work in the Fen District. The present article is a contribution to the work of this Committee, but describes deposits which are earlier in date than those which have been dealt with so far. The marine gravels have long been known near the town of March in Cambridgeshire, and the object here is to collect what is known up to the present (1934) about this deposit and to discuss its relation to the glacial and implementiferous deposits of southern Fenland and in the neighbourhood of Cambridge. The term “March Gravel” will be used here in reference to the sands and gravels which contain marine organisms and which are found on the “islands” between Peterborough on the west and the “Bedford River”, near Manea, on the east.

The Outer Hebrides, lying off the north-west coast of Scotland, are of particular interest to the student of Pleistocene geology, on account of the grand scale on which the results of ice-action are to be seen, and because of the marine shell-beds which are to be found at the northern end of the Isle of Lewis. In the present paper no general survey ofthe glacial deposits of the Outer Hebrides will be attempted; my object is rather to drawattention to certain features of the marine fossils, as a study of the coast sections shows that a faunal sequence can be established in the Pleistocene series.

LARGE collections of material have been brought back by numerous Arctic Expeditions, and, as many writers have pointed out, much of this raised beach material proves changes of climatic and other ecological conditions during Quaternary times. Before correlation of Quaternary deposits in Spitsbergen and other Arctic lands can become at all certain, it is essential that as many detailed contributions as possible should be made to our total collection of facts.
