I have, however, found neitherbeaver nor anything else in this portion of the section ; nor have Iseen remains of the beaver except in a Neolithic peat near Paringdon.At the same time, the beaver was a Pleistocene creature, and hisinfluence in altering a river-landscape was probably at that epochlittle interfered with by man. Even in later times the influence ofthe beaver should be looked for; probably many flat plains uponthe reaches of our rivers owe much of their form to the handiworkof this busy creature in the Neolithic and early historic ages. To complete the description of the river-bed, it should be addedthat the Oxford Clay beneath the gravel is curiously pitted. Thisgravel does not lie in a horizontal plane above the clay, but Allsinnumerable contiguous pits measuring about 3 feet in diameterand 1 foot in depth.

The Associated Fossils. The gravel-bed has proved richly implementiferous. The imple-ments are formed of flint taken freshly from the Chalk, or ofquartzite-pebbles of the Northern Drift, and they are remarkablefor their size, beauty, and freshness. As usual, they have a faciesof their own ; the oval type is rare, and the pointed examples arevery frequently flat or nearly so on one side, belonging to what SirJohn Evans has named the shoe-shaped type. Many of the usual mammalian remains are also found : Elephasprimigenius, Equus cabaUus, Bos prvmigemtis^
