On its eastern and southern sides this district is coterminous with the Upper Tamar and Fowey Districts. Its coast line lies between Tintagel Head and Padstow, but does not include any portion of the northern side of the Camel estuary outside of Padstow town. The road from Padstow to Winnard's Perch, through St. Columb Major to Blue Anchor, is the western boundary, and the Mitchell-Bodmin road from Blue Anchor to the north-western corner of the Fowey District completes the southern line. By far the greater portion of this district is occupied by Devonian rocks. From Padstow towards Port Isaac the lowermost of the series prevail. Upper Devonian overlie these as Camelford is neared. At Blisland Lower Silurian abut on the granite of the western side of the Bodmin Moors and narrow away to Wadebridge on one side, and to Bodmin on the other. From the Lower Devonian between Padstow and Fraddon two bosses of granite arise at Castle- an-Dinas ; another outcrop is exposed at St. Columb. If for botanical purposes river-basins are to be accepted as the most satisfactory of county divisions, this district of the eight into which Cornwall has been marked off for the purpose of this paper is least open to criticism. East and west it is drained by the Camel and its tribu- taries and has no other river or stream of any consequence within its boundary. The Camel itself rises in the parish of Davidstow and with its numerous feeders great and small drains the whole of the north-east. One of its branches, the Lank, drains the Bodmin Moors, start- ing from between Rough Tor and Brown Willy, not far from the origin of the Fowey. Another, the Alan, has its source between Camelford and Delabole Station and pursues an almost straight course to the parent stream, which it joins at Egloshayle. From Pentire Point to St. Tudy and from Wadebridge to Lanivet there are long stretches of low-lying ground, and it has been repeatedly remarked by botanists that the flora of these tracts is distinctly sub-maritime. In the extreme east the country rises to altitudes not reached in any other part of the county. Brown Willy, the giant of Cornwall, rises to 1,375 feet; Rough Tor, 1,296; Hawk's Tor, 1,005 ; Alex Tor, 860. In the west St. Breock Down has an elevation of 739 feet and Castle-an-Dinas 702 feet.
