470 MR, G. ERDTMAN: STUDIES IN THE 
Peat Moss No. 10. (Text-fig. 10.) 
Situated 60 m. N.E. of Sandwick Loch, E. of Stornoway. The thickness 
of the strata is 233 em. It consists of Carex peat, in the upper part 
resembling magnocaricetum peat (H 28), further down containing Meny- 
anthes seeds and Equisetum remains, also rhizomes of Phragmites. The 
base shows a transition to a dark, very much decayed muddy substance 
resting on rock, 
As to the diagram (text-fig. 10), sample 3 shows an unusually well-defined 
maximum of Corylus pollen : consequently this sample seems to be synchro- 
nous with the A-niveau, the frequency of alder-pollen still being rather low.

It is remarkable that in one sample (2) pine-pollen is the dominant (44 per 
cent.). Such high percentages are not met with in western Lewis. How- 
ever, this figure is not well established, for only 25 pollen-grains were 
counted. Pollen of Myriophyllum alterniforum is recorded from sample 4. 
On the seashore S. of Sandwick Loch and a little above the mean high- 
water level, there are two strips of peat, the lower (15 cm. thick) resting on 
shore-gravel and separated by 10 em. of gravel from the upper (10 em. 
thick), which is itself covered by LO em. of gravel, It cannot be doubted 
that these peat-layers have the same history as those described by Samuelsson 
(l.e. p. 244) from the bay between Rudha Shilldinish and Gob Shilldinish, 
south-east of Stornoway. From Sandwick Bay, Lewis (iii, 1907, p. 49)
