2 30 BLAKENEY POINT, NORFOLK Arrived on the Long Hills, it will be noted that the covering of dunes is more mature than anywhere on the Headland itself. More species of plants have settled in, and the lichens (Cladonias) are relatively much more important in covering the ground. There are also numerous fine clumps of the polypody fern— not to be seen elsewhere on the Point. The main object of the visit to the Long Hills is to examine the southern extremity of the bank. Prior to 1911 the end ran straight out, but during the winter of 1911-12 continued tempests from the west destroyed the tip, and re-arranged the shingle as a hook pointing east. This hook is now nearly 200 feet long, and curved like a jetty (Plate XXV, lower photo). Its sudden apparition has disorganized considerably the tidal irrigation of part of the marsh to the east of the Long Hills bank, but its chief interest lies in the fact that its formation explains how the similar curved type of hooks on the Marams arose. These can be inspected on the way back to Cley. The bushes of Suceda fruticosa, now present on the crest of this new bank at its point of insertion, have been derived directly from Suasdas which flourished on the eastern slope of the old bank before the catastrophe. These, when overwhelmed, grew up through the new shingle and took root at the higher level. It is this characteristic, combined with great robustness of habit, that makes Suceda fruticosa potentially one of the most valuable of all maritime plants for purposes of coastal defence, ranking indeed with Psamma itself. The return journey to Cley will be made on foot. Leaving the Long Hills just beyond the house-boat Yankee, a line may be taken direct to the Hood across the sands, or if they are too sloppy, the fringe to the main beach may be followed. The flats on this side of the Long Hills are still for the most part bare of higher plants, except for a thin scattering of Sali-cornia annua, now rapidly spreading. The higher parts between the neap and spring high-water marks on the Long Hills side show very typical development of the blue-green alga Microcoleus, an important accretor of mud. It can be recognized by a tendency shown by the surface layers to flake off during the periods of the neaps in summer. If a specimen be examined
