The tendency of the currents in the Channel opposite Brighton is to drive the shingle eastward, and encroachments of the sea were frequent and serious until the erection of a massive sea-wall, begun about 1830, 60 ft.
South of the Negro the country is arid, barren and lies in great shingle-covered terraces sloping eastward to the Atlantic; its larger part is practically uninhabitable, only the river valleys and the foot-hills of the Andes having a regular water supply.
The succession of beds in descending order is as follows: - (1) Shingle consisting of pebbles of limestone, slate and other local rocks, with fragments of stalagmite and containing a few bones and worked flints.
On the under-side, there are found attached fragments of limestone and quartz, showing that the shingle bed once extended up to it, and that it then formed the original floor.
From these structural and palaeontological evidences, geologists suppose that the formation of the cave was carried on simultaneously with the excavation of the valley; that the small streams, flowing down the upper ramifications of the valley, entered the western opening of the cave, and traversing the fissures in the limestone, escaped by the lower openings in the chief valley; and that the rounded pebbles found in the shingle bed were carried in by these streams. It would be only at times of drought that the cave was frequented by animals, a theory which explains the small quantity of animal remains in the shingle.
Thenceforth everyone who built a house was strictly charged not to cover it with reeds, rushes, stubble or straw, but only with tiles, shingle boards or lead.
Hard rock (mostly granite and crystalline schists, with red sandstone in places) appears only in the transverse glens, which are often choked with their debris in the form either of gravel-and-shingle or loose blocks of stone or both.
To the latter belong the Greenshank and Redshank, as well as the Common Sandpiper, the " Summer-Snipe " above-mentioned, a bird hardly exceeding a skylark in size, and of very general distribution throughout the British Islands, but chiefly frequenting clear streams, especially those with a gravelly or rocky bottom, and mast generally breeding on the beds of sand or shingle on their banks.

They generally breed in association, often in the closest proximity - their nests, containing three eggs at most, being made on the shingle or among herbage.
North of the Needles there springs from the mainland a great shingle bank, mostly only a few yards in breadth above water, but nearly 2 m.
Natural scalps are subject to extreme vicissitudes: an area of many acres may be destroyed by a local change of current producing a deposit of sand or shingle over the scalp, or by exposure to frost at low tide in winter, or by accumulation of decomposing vegetable matter.
The formation of the coast varies from low, shifting banks of shingle or sand to majestic cliffs, and its character in different localities has been foreshadowed in the previous consideration of the hill-systems and lowlands.
They are hemmed in and separated by snowcapped mountain peaks and ridges, which are seamed with glaciers terminating in moraines and shingle slopes at the base of the foot-hills.
ISLE OF PORTLAND, properly a peninsula of the coast of Dorsetshire, England, as a prolongation of a narrow ridge of shingle, Chesil Bank, connects it with the mainland.
