This deposit I have hitherto been led to regard as a southerly con-
tinuation of the Lower Boulder-clay of Lancashire, Cheshire, &c.
(see my former paper, and the concluding part of this paper).
Drift-
around Nuneaton, Coventry, Kenilworth, and
Leamington.
In this area the drift-matrix consists of redistributed local shale,
clay, or marl belonging to the Triassic, Permian, or Carboniferous
formations. The stones, in addition to quartzose and other pebbles,
consist of flints, a few chalk fragments, and erratics from the Pennine
hills, Charnwood forest, HartshiU, and fragments or fossils of Jurassic
rocks. These erratics (which chieiiy came from the north and east) are
commonly imbedded in what is locally called " top clay," of a brown or
red colour, which graduates downwards into underlying marl, shale,
&c. This clay contains chalk flints (rather fitfully distributed, but
generally very little chalk debris. In one of the Kenilworth gravel-
pits the redeposited Triassic pebbles, intermixed with large angnlar
chalk flints and coal-dust, graduate downwards into a pell-mell local
boulder-loam, which is probably the equivalent of the Wolverhampton
and Stafl'ord Boulder-clay, ^t Lillington, near Leamington (in
1865), the red marl, with a few stones near its surface, was overlain
by a mass of stratified fine gravel, consisting of Triassic pebbles,
Gn/phites, &c., above which there was a considerable thickness of
obliquely laminated fine sand, surmounted by 2 feet of clay with
pebbles (see fig. 2). In 1878 no section was exposed lower down

than the fine sand. At the Stoke-Heath clay-pits, near Coventry,
the clay (which contained a large boulder, probably from Charnwood
forest) here and there graduated into gravel on the same horizon,
and contained a few (but only a few) chalk-f.-agments and chalk-
flints. Around Nuneaton the clay (with "trap " boulders) contained
many flint chips and small Triassic pebbles, but scarcely any chalk;
and the specimens of the clay I brought away with me did not
efi'crvesce with ordinary tests. Xear Ilugby railway-station (March
