CHEVIOT HILLS
, a range forming about 35 M. of the border between See also:England and See also:Scotland
.
The boundary generally follows the See also:line of greatest See also:elevation, but as the slope is more See also:gradual southward and northward the larger See also:part of the range is in See also:Northumberland, England, and the lesser in See also:Roxburghshire, Scotland
..
The See also:axis runs from N.E. to S.W., with a northward tendency at the eastern end, where the See also:ridge culminates in the Cheviot, 2676 ft
.
Its See also:chief elevations from this point See also:south-westward fall abruptly to 2034 ft. in Windygate See also:- HILL

Hill, and then more gradually to about 7600 ft. above the pass, followed by a high road from See also:Redesdale
.
Beyond this are See also:Carter See also:Fell (18r5) and See also:Peel Fell (1964), after which two lines of lesser elevation See also:branch westward and. southward to enclose See also:Liddesdale
.
The hills are finely grouped, of conical and high-arched forms, and generally grass-covered
.
Their flanks are scored with deep narrow glens in every direction, carrying the headwaters of the Till, See also:Coquet and See also:North See also:Tyne on the south, and tributaries of the See also:Tweed on the north
.
The range is famous for a valuable breed of See also:sheep, which find abundant pasture on its smooth declivities
.
In earlier days it was the See also:scene of many episodes of border warfare, and its name is inseparably associated with the ballad of Chevy See also:Chase
.
The See also:main route into Scotland from England lies along the See also:low coastal See also:belt See also:east of the Till; the Till itself provided another, and Redesdale a third
.
There are numerous ruins of castles and " peel towers " or forts on the See also:English See also:side in this See also:district
.
See also:Geology.—The rocks entering into the See also:geological structure of the Cheviots belong to the See also:Silurian, Old Red See also:Sandstone and Carboniferous systems
.
The eldest strata, which are of Upper Silurian See also:age, See also:form inliers that have been exposed by the denudation of the younger palaeozoic rocks
.
One of these which occurs high up on the slopes of the Cheviots is drained by the Kale See also:Water and the See also:river Coquet and is covered towards the north by the Old Red Sandstone volcanic See also:series and on the south by Carboniferous strata
.
Another See also:area is traversed by the Jed Water and the Edgerston See also:Burn and is surrounded by rocks of Old Red Sandstone age
.
The strata consist of greywackes, flags and shales with seams and zones of graptolite shale which yield fossils sparingly
.
On the upturned and denuded edges of the Silurian strata a See also:great See also:pile of contemporaneous volcanic rocks of See also:Lower Old Red See also:Sand-See also:- STONE
- STONE (0. Eng. shin; the word is common to Teutonic languages, cf. Ger. Stein, Du. steen, Dan. and Swed. sten; the root is also seen in Gr. aria, pebble)
- STONE, CHARLES POMEROY (1824-1887)

stone age rests unconformably, which consists chiefly of lavas with thin partings of See also:tuff
.
A striking feature is the See also:absence of coarse sediments, thus indicating prolonged volcanic activity
.
They See also:cover an area of about 230 sq. m. in the eastern part of the Cheviots and rise to a height of 2676 ft. above the See also:sea
.
The lavas comprise dark See also:pitchstone, resembling that at See also:Kirk See also:Yetholm, and porphyritic and amygdaloidal andesites and basalts
.
This volcanic See also:platform is pierced by a See also:mass of See also:granite about 20 sq. m. in extent, which forms the highest See also:peak in the Cheviot range
.
It has been described by Dr Teall as an See also:augite-See also:biotite-granite having strong See also:affinities with the augite-bearing granitites of Laveline and Oberbruck in the See also:Vosges
.
Both the granite and the surrounding lavas are traversed by dykes and sills of intermediate and See also:acid types represented by See also:mica-porphyrites and See also:quartz-felsites
.
On their north-See also:west margin the Lower Old Red volcanic rocks are covered unconformably by the upper See also:division of that See also:system composed of red sandstones and conglomerates, which, when followed westwards, See also:rest directly on the Silurian platform
.
Towards the south and east the volcanic pile is overlaid by Carboniferous strata, thus indicating a prolonged See also:interval of denudation
.
On the See also:northern slopes of the western part of the Cheviots the representatives of the Cementstone See also:group of the Carboniferous system come to the See also:surface, where they consist of shales, See also:clays, mudstones, sandstones with cementstones and occasional' bands of marine See also:limestone
.
These are followed in normal See also:- ORDER
- ORDER (through Fr. ordre, for earlier ordene, from Lat. ordo, ordinis, rank, service, arrangement; the ultimate source is generally taken to be the root seen in Lat. oriri, rise, arise, begin; cf. " origin ")
- ORDER, HOLY
order by the Fell Sandstone group, comprising a See also:succession of sandstones with intercalations of red and See also:green clays and impure cementstone bands
.
They form the higher part of the Larriston Fells and are traceable eastwards to Peel Fell, where there is See also:evidence of successive See also:land surfaces in the form of dirt beds
.
They are succeeded by the See also:Lewis-burn See also:coal-bearing group, which represents the Scremerston coals
