PHYSICAL FEATURES AND GEOLOGY

Оглавление

There is a prevalent belief that the picturesque part of the West of England begins with Devon and ends with Cornwall, to which Somerset is merely a stepping-stone. This opinion is no doubt fostered by the impression which the tourist derives of the county through the carriage windows of the "Cornishman." But the considerations that appeal to the railway engineer are mechanical rather than aesthetic; and, unfortunately for the reputation of Somerset for scenery, the line of least resistance is the line of least interest—the dead level skirting the coast between Bristol and Taunton. As a matter of fact, there are few districts which afford such a variety of physical features as Somerset. Hill and valley, cliff and chasm, moor and seaboard, are all to be found there; and, in addition to its wealth of scenery, Somerset is rich in antiquities of different kinds; whilst it has also been the theatre of some of the most stirring events in English history.

The physical skeleton of the county may be roughly described as consisting of three parallel ranges of hills running transversely across it—the Mendips and their outliers in the N.E., the insignificant Poldens in the centre, and the Quantocks and Exmoor in the W., with the Blackdowns occupying the S.W. corner. The intervening basins are filled with a rich alluvial deposit washed down from the hills or left by the receding sea. The Mendips spread themselves across the E. end of the county in a N.W. direction from Frome to Weston-super-Mare, where they lose themselves in the Channel, to re-appear as the islets of the Steep and Flat Holms. On their S.W. side they descend into the plain with considerable abruptness; and when viewed from the lower parts of the county, present a hard sky-line, like some enormous earthwork. On the opposite side their aspect in general is far less impressive, and towards Bath they lose themselves in a confusion of elevations and declivities. The main ridge is an extended tableland, some 25 m. long, and in places 3 m. broad. It rises to its greatest heights at Blackdown (1067 ft.) and Masbury (958). Geologically, it consists of mountain limestone superimposed on old red sandstone, which here and there comes to the surface. Near Downhead there is an isolated outburst of igneous rock. The Mendips are honeycombed with caverns, the most notable being at Banwell, Harptree, and Burrington; and a large one has been recently discovered some 4 m. from Wells. At Cheddar their W. edge is broken by a remarkable gorge, in the sides of which caves also occur. The level of the tableland is indented with "swallet holes," the chief of which are the East Water Swallet and the Devil's Punch-Bowl. The Quantocks are much less extensive, though their highest summits rise to a greater altitude. Like the Mendips, they turn their steepest flank westwards, the ascent on the E. being gradual; and on this side they are cut by a number of well-timbered and delightful combes. Few caves have been discovered in them, though there is one at Holwell near Asholt. W. of the Quantocks are the Brendons and the highlands of Exmoor, the latter extending into Devon, though their highest point, Dunkery Beacon, is included in Somerset. Dunkery is 1707 ft. above the sea-level; and other conspicuous hills in this district are Lucott Hill (1516), Elworthy Barrow (1280), Selworthy Beacon (1014), and Grabbist Hill. The Quantocks, Brendons, and Exmoor consist of older rocks than the Mendips, belonging as they do to the Devonshire series of old red sandstones. Bordering the Brendons are found the red marls of the Permian series; whilst between Dunster and Williton, and along the base of the Quantocks, in the neighbourhood of Taunton Dean, as well as in some other localities, Keuper and Rhaetic beds occur. The Blackdowns in the S.W. are not quite so elevated as their neighbours; near Otterford and Chard they consist of greensand, whilst chalk appears at Combe St. Nicholas and Cricket St. Thomas. The centre of the county is alluvial, and beneath it the limestone of the Mendips sinks, coming to the surface again in the W. only at a single spot, near Cannington. Out of this central plain rise several isolated, cone-like hills, the most notable being Glastonbury Tor and Brent Knoll. These belong to the lias and lower oolite rocks. The Poldens consist of lias; and the same formation constitutes the rising ground that bounds the plain on the S. and E. of the county. The southern side of the Poldens is edged with Rhaetic beds, which also extend to High Ham. Oolite rocks occur abundantly near Bath, furnishing the famous Bath building-stone; and they likewise form the prominent eminence of Dundry. Near Frome they rest upon the mountain limestone. The same series of rocks occupies the S.E. corner of the county, extending from Milborne Port to Bruton. On the E. they are flanked with the Oxford clay, which reaches from Henstridge to Witham Friary, whilst a ridge of higher ground near Penselwood consists of greensand. Near Radstock coal is found.

The Somerset sea-coast, though destitute of ruggedness and grandeur, possesses undeniable charm, at least at its W. and E. extremities; but it lapses into unquestioned tameness where the sea washes the central flats. The waters of the Bristol Channel as far down as Minehead are discoloured; and, with the exception of a range of low cliffs near St. Andries and Watchet and a stony foreshore at Clevedon, there are no rocks worth mentioning. Brean Down and the North Hill near Minehead are the only headlands, but notwithstanding this, the watering places of Somerset are breezy and healthy. Weston-super-Mare in particular has a high reputation for salubrity, and has long been one of the most popular seaside resorts in England.

Somerset is peculiarly deficient in large rivers, for the Avon can hardly be included amongst its belongings, since it is the dividing line between the county and Gloucestershire. The Parrett is the one stream of any moment. It is a sluggish and uninteresting bit of water, rising in Dorset, entering Somerset near Crewkerne, and flowing, when it meets the tide near Bridgwater, with a wearisomely circuitous course of some 12 m. before it mixes with the Bristol Channel. The other rivers, the Frome and Chew, which join the Avon; the Axe, which rises in Wookey Hole and enters the sea near Brean Down; the Brue and Cary, which empty themselves into the estuary of the Parrett; and the Parrett's own tributaries, the Yeo, Ivel, and Tone, are unimportant. Exmoor is drained by the Exe and Barle, which, when united, flow southward into Devon.

Such, however, is the character of Somerset scenery that the absence of water in it is hardly noticed. From what has been said it will be seen that the county has much in it to arrest the attention of the traveller who can appreciate quiet beauty, and, as will appear, even more to appeal to one who is interested in his country's-past, whilst upon the affection of its sons its hold is indisputable. As one of them writes:—

"Fair winds, free way, for youth the rover;

We all must share the curse of Cain:

But bring me back when youth is over

To the old crooked shire again.

Ay, bring me back in life's declining

To the one home that's home for me,

Where in the west the sunset shining

Goes down into the Severn sea."
