MAN AND THE GLACIAL PERIOD.

A little above Hoxne, on the left side of the stream called the Gold Brook, is the Hoxne clay-pit. The clay is excavated along the slope of the shallow valley through which the brook runs. The road to Eye skirts the hill-side, having to the west the park of Sir Edward Kerrison; and to the east, between it and the stream, a narrow strip

Fig. 3.—Theoretical Section according to Prof.Preswich: 2. Surface gravels. 3. Brick, earth, and gravel, with flint implements, mammalian remains, and land and fresh-water shells. 3. Peaty bed,with wood and land and fresh-water shells. 4. Bowlder-clay. 5. Sands and gravels. 6. Chalk, probably.

Fig 4.—Section showing the Actual Facts observed: 1. Surface gravels, "trail." 2. Clay resembling "upper bowlder-clay." 3. False-bedded sands and gravel flint. 3. Brick earth, flint implements scarce, land and fresh-water shells in lower part. 5. Gravel, many flint implements found by Mr. Frere. 6'. Lower bowlder-clay and "till." 7. Peaty bed.

of land from which the clay has been dug. The old workers had commenced near the village of Hoxne, and as they gradually exhausted the clay up to the road they moved farther southward, and the point at which it is now excavated is probably at least a quarter of a
