been universal till the Roman era, the earlier British method being
to bruise the grain in a mortar.[28] Without the resources of
civilization it is not easy to deal with stones hard enough for
satisfactory millstones. We find that the Romans, when they came,
mostly selected for this use the Hertfordshire "pudding-stone," a
conglomerate of the Eocene period crammed with rolled flint pebbles,
sometimes also bringing over Niederendig lava from the Rhine valley,
and burr-stone from the Paris basin for their querns.

E. 7.--These tribes are described as living in cheap [[Greek:
euteleis]] dwellings, constructed of reeds or logs, yet spoken of as
subterranean.[29] Light has been thrown on this apparent contradiction
by the excavation in 1889 of the site of a British village at
Barrington in Cambridgeshire. Within a space of about sixty yards
each way, bounded by a fosse some six feet wide and four deep, were
a collection of roughly circular pits, distributed in no recognizable
system, from twelve to twenty feet in diameter and from two to four in
depth. They were excavated in the chalky soil, and from each a small
drainage channel ran for a yard or two down the gentle slope on which
the settlement stood. Obviously a superstructure of thatch and wattle
would convert these pits into quite passable wigwams, corresponding to
the description of Pytheas. This whole village was covered by
several feet of top-soil in which were found numerous interments
of Anglo-Saxon date. It had seemingly perished by fire, a layer of
incinerated matter lying at the bottom of each pit.

E. 8.--The domestic cattle of the Britons were a diminutive breed,
smaller than the existing Alderney, with abnormally developed
foreheads (whence their scientific name _Bos Longifrons_). Their
remains, the skulls especially, are found in every part of the land,
