AUSTEN LAND-SURFACES BENEATH DRIFT.

stratified gravel-beds of Brook, which belong to the central valley
area, over a terrestrial surface of the same age as that of St. Helens,
tends to refer all the gravels spread over the surface of the tertiary
series to one and the same group.
Coast of France. — On the evidence that masses of peat were
brought up in trawls from parts of the sea-bed off the French coast
(Pas de Calais, Department of the Somme), — and that over the same
spots the remains of Elephas primigenius were very frequent as well
as perfect, I ventured on the opinion that these parts of the Channel
had formed part of the dry-land-surface of the period of that fauna.
Some observations by French geologists (Rozet) respecting a toiirbe
du Diluvium indicated that they had seen instances of terrestrial
surfaces beneath the gravel-drift ; none of them, however, have been
particularly indicated. It was therefore with much interest that, in
conjunction with several members of this Society, I met with such a
case in the course of a geological excursion in the spring of last year.
The place at which the section, fig. 2, was taken, is about half-way
between Dieppe and the Lighthouse of St. Marguerite. The beds
are cut off by the cliff as represented in the sketch. The portion
remaining has a slight basin-shaped arrangement, as if the vegetable
and sedimentary matter had been collected in some local depression.
The underlying beds belong to the lower Eocenes ; and above are thick
water-strewn beds of flint-gravel. Mr. D. Sharpe collected in the
deposit in question the remains of insects.

This image is in the public domain because it is a mere mechanical scan or photocopy of a public domain original, or – from the available evidence – is so similar to such a scan or photocopy that no copyright protection can be expected to arise. The original itself is in the public domain for the following reason:
Public domain

This work is in the public domain in its country of origin and other countries and areas where the copyright term is the author's life plus 70 years or fewer.


This work is in the public domain in the United States because it was published (or registered with the U.S. Copyright Office) before January 1, 1929.


This tag is designed for use where there may be a need to assert that any enhancements (eg brightness, contrast, colour-matching, sharpening) are in themselves insufficiently creative to generate a new copyright. It can be used where it is unknown whether any enhancements have been made, as well as when the enhancements are clear but insufficient. For known raw unenhanced scans you can use an appropriate {{PD-old}} tag instead. For usage, see Commons:When to use the PD-scan tag.


Note: This tag applies to scans and photocopies only. For photographs of public domain originals taken from afar, {{PD-Art}} may be applicable. See Commons:When to use the PD-Art tag.
