In the valley sides around the town of Brandon, in England, "are preserved patches of brick-earth, which are valuable as affording the only workable clay in the district. Whenever these beds are well exposed they are seen to underlie the chalky boulder-clay of glacial age.
Then fire destroyed all her mediæval architecture, leaving her only Westminster Abbey to suggest the greatness of her losses. But brick-earth and fire have been as nothing in their way by the side of the evil wrought by Gog and Magog.
In that of the Neckar, for example, near Tubingen, I found the fluviatile loam or brick-earth, enclosing the usual Helices and Succineae, together with the bones of the mammoth, very distinct in colour and composition from ordinary Rhenish loess, and such as no one could confound with Alpine mud.
On March 26th, 1667, the two went in search of brick-earth, and in September articles were drawn up between them for the purpose of proceeding in the manufacture. In April, 1668, Evelyn subscribed 50,000 bricks for the building of a college for the Royal Society, in addition to L50 given previously for the same purpose.
Rigollot, in this memoir, pointed out most clearly that it was not in the vegetable soil, nor in the brick-earth with land and freshwater shells next below, but in the lower beds of coarse flint-gravel, usually 12, 20, or 25 feet below the surface, that the implements were met with, just as they had been previously stated by M. Boucher de Perthes to occur at Abbeville.
The strata of brick-earth, loam, and gravel exposed to view in artificial excavations in that spot, are precisely such as would be formed by the silting up of an old river channel. It is associated with Unio littoralis also in great numbers and with both valves united.
These river-gravel and brick-earth buried bones are rather earlier than those found in the peat and marl. The latter belonged to creatures which, though they no longer exist in England, are still found in temperate Europe beavers, bears, bison, and wolves.
Sometimes an island is formed in midstream, the current flowing for a while on both sides of it, and at length scooping out a deeper channel on one side so as to leave the other to be gradually filled up during freshets and afterwards elevated by inundation mud, or "brick-earth."

No. 3 represents an older alluvium, composed of sand and gravel, formed before the valley had been excavated to its present depth. It contains the remains of fluviatile shells of living species associated with the bones of mammalia, in part of recent, and in part of extinct species. No. 3' is a remnant of the loam or brick-earth by which No. 3 was overspread.
