A Considerable length of section of the river valley-gravel has recently been laid open in the grounds of St. Edward's School, Summertown. It is only 200 or 300 yards distant from the Suvnmertown brick-pit, where the same gravel is exposed, and which is there close on the edge of the Thames valley; nevertheless, this section presents features which have not been observed there or at any other place, numerous as are the sections of the superficial gravel and sand in the neighbourhood of Oxford.
