638 PROF. W. BOYD DAWKINS ON [Nov. 1902, 
VI. Tae Rance oF THE PrEL SANDSTONES AND STACK SERIES 
to tHE NortrH-East ALONG THE Coast. 
The Stack Series forms the headland to the 
north-east of Traie Fogog, and ranges as far 
as Lhooby Reeast, where the easterly trend 
of the coast brings in again the bright red 
and variegated beds below (fig. 4, D). 
The cliffs and foreshore from Lhooby Reeast, 
for 1150 feet to the north-east, are formed of 
bright red sandstone, more or less mottled 
(fig. 4, D), dipping north 20° west at an 
angle of 40°. In the little bay south of Cass 
Stroan, they are faulted against the dull red 
sandstones with breccias of Traie Fogog 
(fig. 4, C). Here their dip is 34°, north 
18° west, while that of the latter is 10°, north 
18° west, the downthrow being to the south- 
oh west. 
fae From this fault the dull red sandstones (C) 
Hi with breccias and conglomerates, in some 
places sun-cracked and mottled grey, range 
along the coast with an uniform dip north 
18° west, of 14°, as far as the fault in 
the headland, between Cass Stroan and Cain’s 
Strand. At this point the red variegated 
sandstones (D) are thrown down against OC, 
and are seen in the cliffs and foreshore of 
Cain’s Strand, as far as the fault marked on 
the foreshore by a cave. To the north-east 
of this fault the cliffs are sheared and broken, 
as far as the south-western headland of 
Whitestrand Bay, the smashing culminating 
in a fault full of crushed rock about 20 feet 
broad. Still farther north-eastward the dull 
red sandstone-strata are unbroken, and dip 
gradually underneath the bright red and 
mottled beds (D). These pass underneath 
the Stack Series (EK), which occupies the 
foreshore and forms the low cliff extending 
as far as an overthrust-fault, abruptly cutting 
them off close to the northern headland. At 
this point, the dull red sandstones of the 
lower series (C) rest upon the Stack Beds, and 
are folded, sheared, and smashed, as far as 
the southern portion of Will’s Strand. Here 
they dip under the unbroken strata, ending 
in the north-east in a stack composed of 
breccia and conglomerate, close to the great.
