LAMPLUGH : OX THE SUPPOSED RAISED BEACH AT SALTBURX. 347 
slope of the ravine of Skeltoii Beck, just within the boundary of the 
pleasure-grounds. On the flat i)art of the terrace the continuation 
of the sand was seen, up to a depth of 6 ft., again with a few shells, 
including two species of Littorina (some being of large size), Naiiea, 
Trochus, Cardiam (fragmentary), and the small land shells as before. 
Just under the fence of the gardens some large slabby stones, up to 
8 inches in diameter, occurred half-way down in the sand, along with 
some smaller stones reddened by fire, the whole being suggestive of 
an old hearth -place. In another s])ot a lenticle of subangular gravelly 
wash, up to 9 inches thick, set in between the sand and the underlying 
red boulder-clay. It contained no shells and was not like a beach- 
gravel, but resembled river-wash. 
Where the terrace narroyved toward its southern termination, the 
sand became mixed and streaked with red loam, evidently the result 
of rain-wash from the neighbouring slope of boulder-clay. A more 
clayey rain-wash covered the slope a little farther southward, where 
there was no sand, and this clay-wash (which might readily be mistaken 
for boulder-clay in place), itself contained some large periwinkle shells, 
like those in the sand. 
At the opposite or eastern side of the valley, the sections ran 
continuously along the steep slopes of the weathered cliff of drift 
behind Old Saltburn, at about the same level as on the w^estern side. 
They were all in red boulder-clay, with here and there a patch of silt 
or of clayey gravel, evidently recent slope- wash, but in three or four 
places they crossed superficial pockets of shells of Littorina and Patella, 
These shell-pockets were a foot or two wide and two or three inches 
deep, and in one place included some bits of bone. They were clearly 
artificial ' kitchen-midden ' heaps, and probably of no great antiquity. 
Heaps of limpet shells of this kind are commonly left in such situations 
in the recesses of the coast by fishermen in baiting their lines ; but I 
am not aware that the periwinkle is used in this way for bait. The 
shells noticed by Dr. Yeitch on this slope are explained by the presence 
of these pockets, which have certainly nothing to do with a raised 
beach. 
As regards the terrace with its sandy deposit west of the beck, I 
am satisfied, after seeing the sections, that this also is not a raised 
beach, although the feature at first sight suggests such origin. The 
sand has all the characteristics of a l)lown sand. In structure, texture 
and general aspect, it resembles the blown sand of adjacent slopes.
