to the west and the West Riding of Yorkshire, including a small area of the city of Sheffield, to the north (Fig. 1, opposite). Its greatest length from north to south is nearly 40 miles and its greatest breadth about 24 miles. The boundary which delimits the park would enclose a broadly oval shape but for the long narrow wedge reaching far into the interior from New Mills on the western margin to a point about five miles south-east of Buxton. This territory was excluded on the grounds of its predominantly industrial character; in it lie the towns of New Mills, Whaley Bridge, Chapel-en-le-Frith and Buxton, while around the last-named the landscape is seriously marred by intensive limestone quarrying and related lime-works. This feature has the effect within the Park of severing the High Peak of Derbyshire from the hill country of East Cheshire. On the south-east side for a similar reason, though without giving rise to a pronounced wedge, the Matlock and Darley Dale section of the Derwent valley was also excluded. On the south and west the towns of Wirksworth, Ashbourne, Leek and Macclesfield have all been omitted, though they lie only a little beyond the boundary.

      Incidentally, two points concerning nomenclature should be mentioned here. In the first place, the term Peak District applies to the upland area of Derbyshire as a whole. There is no single mountain or summit named The Peak. The highest part of the area is in the extreme north where the two flat-topped moors of Kinderscout and Bleak Low both reach to over 2,000 feet. The highest point of all is on Kinderscout reaching 2,088 feet. Secondly, a distinction is sometimes made between the northern and southern parts of the upland. These are known respectively as the High Peak and Low Peak but the distinction is a vague one and is not based on altitude alone.

      From the standpoint of administration the Peak National Park is managed by a central authority in the form of a Joint Planning Board consisting of 27 representatives, of whom 18 are appointed by the constituent county authorities and the county borough of Sheffield, and the remaining nine by the Minister of Housing and Local Government. The Peak Planning Board has its own technical department at Bakewell under the direction of a Planning Officer. This form of administration is the only example of the method originally envisaged for the national parks although in one or two other instances the form adopted approximates to it. On the whole in the case of The Peak it has worked successfully. Certainly, by excluding a number of urban centres situated on the fringe of the Park, general planning problems connected with the location of industry and urban growth and re-development have been considerably reduced, enabling the Planning Board to devote its attention more wholeheartedly to the special interests of the Park.

       THE ROCKS AND THEIR HISTORY

       The hills are shadows, and they flow

       From form to form, and nothing stands;

       They melt like mist, the solid lands,

       Like clouds they shape themselves and go.

      ALFRED TENNYSON: In Memoriam

      A WANDERER returning to his native village in the Peak District finds his favourite haunts unchanged. The dales and streams, cliffs, hills and moors are all just the same as they were in his youth. If, however, he has studied the rocks they tell him that this peaceful, enchanting scene is but an episode in a long and eventful story which moves so slowly that for the brief period of his lifetime it seems to have been at a standstill. His going and coming have been no more than the flicks of a fly’s wings. That story is recorded for him in the rocks of the district; in the limestone of the uplands on the south; in the grits capping the moorlands of the north and forming the ridges which girt the uplands on either side; and in the shales which underlie the fertile vales that lie between the areas occupied by these two types of rock (Fig. 2, see here).

      THE FOUNDATION ROCK

      Out in the open, beyond the bounds of the stone lily forests, lay coral reefs. These were produced by the combined activities of myriads of polyps. Superficially they resembled modern reefs but the structural details of the individual corals were strikingly different. Surrounding the forests and reefs were spacious wastes of mud formed from the shells and bodies of minute organisms which fell in a perpetual drizzle from the waters overhead. Burrowing in the mud or crawling over its surface were many worms and other creatures that fed upon the mud or caught the drizzle as it fell. These latter included lamp-shells, a type of animal that is scarce today but was then varied and numerous and played a much more important part in the economy of the sea floor. Like cockles and mussels their bodies were also enclosed in shells, often prettily shaped and ornamented. They were usually small shells but some were giants a foot or more in diameter.

      Of special interest were certain curious molluscs belonging to the far-off ancestral stock of the Pearly Nautilus which lives today in the waters of the Pacific Ocean. Like this, they had shells which were divided into a succession of chambers separated by thin partitions. One large type is known as Orthoceras because its shell was straight and not closely coiled like that of the nautilus. Provided with a battery of tentacles round its mouth and with an apparatus for jet propulsion, it preyed upon fishes and other more peaceful creatures. The Goniatites were much smaller
