we find that the chalk range subsides for an mteryal, and gives way
to a low tract covered superficially with gravel. This accumulation is
spread out westward along the valley of the Wey, and abuts against
the ridge of lower greensand which bounds the stream, and which
evidently defined its limits. In other places the gravels thin out
against the slopes of the higher ground, as underneath Crooksbury,
where their sides are occupied by it : good instances and sections may
be seen, first, in the cutting near the Mill, and on the road to Moor
Park, as also in the Pine-wood beyond Waverley : the teeth and the
tusks of elephants have been lately met with in these gravels, in extra-
ordinary abundance. The character of the accumulation about Farn-
ham is better conveyed by a woodcut illustration than by verbal de-
scription (fig. 3).
From Farnham the gravel beds pass outside the chalk range, and
not the slightest trace of them is to be found in the valley between
the escarpment of the chalk and the hne of hills south of it. At Guild-
ford the gravel passes through the break in the chalk, and is thence
spread out over the area of the Peasemarsh (fig. 4), and ends ofp with
an uniform level against the base of the hills which encircle this
valley. The remains of elephants, as well as of other animals, are
very abundant at this place. The railway-cutting from Guildford to
Godalming (fig. 5), and from Shalford to Postford (fig. 6), has given

sections of these gravel beds ; which indicate clearly their marginal
character, by the mixture of gravel and shingle with sands diagonally
arranged. The boundary-line is here also well-defined.
The condition of this part of England antecedent to the accumula-
tion of the pleistocene beds is well shown in the Peasemarsh : the
remains of trees are found beneath the gravels with elephants' teeth
and tusks ; in one instance so many bones occurred together, in the
clay which underlies the gravel, as to warrant the conclusion that an
entire skeleton was buried at that spot.
A north and south section from this marginal line of drift, as from
Guildford or Farnham to between Brighton and Rottingdean, would
