On account of the important part which the Holderness drifts have played in connection with the theories of the glaciation of the country generally, it is proposed to place on record particulars of what is perhaps the finest artificial section in the English glacial series extant. The section has been made in a rounded hill, which is situated between the well-known Kelsey Hill and Burstwick gravel pits, and lies between the 25 ft. and 50 ft. contour lines. (Fig. 1.) In 1902 the North Eastern Railway Company commenced excavations by making a cutting across the eastern flank of the hill. Since then this cutting has been extended and deepened, and details of the beds as exposed from time to time have been carefully sketched, and in this way particulars of the structure of the entire hill have been secured. Fig. 1 illustrates the easternmost section seen, and is entirely in boulder clay. Fig. 2 represents the same face when cut back 50 yards, and shows round tongue-like masses of the shelly gravel appearing at the base of the cutting from beneath the boulder clay. Fig. 3 represents the section parallel to the former, but still further west, and shows the shelly sand and gravel taking the place of the boulder clay almost throughout the section. Four of these sketches are given on Plate XXI., and illustrate parallel sections right across the eastern flank of the hill from north to south, and about 50 yards apart. The present section (Fig. 4, ...
