10 PROF. T. G. BONNEY ON THE GEOLOGY 
dipping apparently to points between N. and N.N.W. I place the 
actual junction, which I have no doubt is a faulted one, about 200 
yards 8. of where it is drawn on the Geological map ; for I succeeded 
in tracing the slaty rock almost to this point *, and then after a few 
yards’ interval (the rock hereabouts being very imperfectly exposed) 
found an indubitable mica-schist of rather chloritic aspect. Beyond 
this, at a slight headland, is a very “‘ gnarled” greenish schist, and 
at the headland bounding the little bay chloritic schist appears 
to rise from below the mica-schist. 
Along the shore of the inlet leading to Batson, which cuts 
obliquely across the above-named beds, we have chloritic schist . 
more or less banded with mica-schist, and at last, near the inlet 
leading to Snapes Farm, these appear to be overlain by a con- 
siderable thickness of darkish mica-schist 7. 
The town of Salcombe is scattered over a headland formed of 
chloritic schist (fig. 5), of which rock many exposures will be found 
by searching; but a band of mica-schist occurs near the base, as may 
be seen in an alley not far from the ferry; and at the upper part of 
the hill is found a considerable mass of mica-schist, resembling 
that already described, and clearly overlying the chloritic schist. 
This is, in all probability, continuous with a mica-schist exposed in 
a quarry to the west of Shabicombe, on the road to Marlborough. 
From Salcombe to North Sands the coast, for the reasons given 
above, is generally difficult of access. So far as I could ascertain, 
the rocks are chloritic schist, but in one or two places I observed 
bands of mica-schist underlying the basal part of the former rock. 
In the southern flank of the hill, forming the northern boundary 
of North Sands, the chloritic schist, here pretty well banded, is 
quarried. The dip is steep, approximately to S. The same rock 
forms the headland dividing North Sands from South Sands; but by 
the roadside, low down on its southern face, we find a darkish mica- 
schist and on the shore at its base chloritic and mica-schists are 
interbedded and, I think, repeated by minor fiexures.. The general 
strike is about E. and W., but it is difficult to say whether the 
dominant dip is northwards or southwards. On the south side of 
the little bay called South Sands is a darkish mica-schist, the com- 
mencement of the great mass which forms the Bolt Head. The rock 
is greatly disturbed and “gnarled.” At first I inclined to the view 
that the whole rose up steeply from beneath the chloritic schist, but 
on repeated examination I fancied I could detect some indication 
of bedding which gave a southerly dip, and after studying spe- 
cimens with the microscope, and a review of the whole evidence, 
I think it more probable that the Bolt-Head mica-schist is only 
a repetition of the upper schist of the Salcombe hill and is thus a 
continuation of that already noticed on the eastern side of the 
estuary. The Bolt Head, so far as I could see, is a mass of darkish 
mica-schist, the general strike of which appears to be a few degrees 
* About 80 yards from a gate, opening from the shore into a field,
