FLOOD OF 1099. 121 
Perranzabuloe, now in 2¢s turn enveloped by sand 
through the violence of the Atlantic exerted on a 
low and exposed coast, is considered to have been 
built about the year 1100. Still further, I would 
observe that the occurrence of this flood so de- 
structive in its consequences in other spots,—and 
- as I have shewn, probably here likewise,—may have 
originated the idea among some, that it was in this 
comparatively modern epoch the sea enveloped the 
land between St. Michael’s Mount and the Land’s 
End, and overwhelmed the forests before spoken 
of. But, surely an invasion so remarkable in effect 
would have been preserved to us in circumstantial 
record had it happened in that era. It would ap- 
pear, that prior to the latest centuries the Church 
of Plympton St. Mary built in low ground, suffered 
very greatly by encroachment of the water of the 
neighbouring marshes, so much so indeed as to 
cause the erection of an elevated aisle on that side 
chiefly affected. For the same reason, the ancient 
Church of St. Budeaux on the banks of the Tamar 
was removed, and the present one built in its lieu. 
On the whole therefore it may be allowable to infer, 
that conjointly the flood above recorded, and the 
perpetual violence of the Atlantic, have succeeded 
in the more modern eras in restraining somewhat 
the tendency of the ocean to recede, and in effecting 
invasions on our coasts which have been preserved 
with some exaggeration in the hereditary traditions 
of succeeding ages. 
With regard indeed to the invasions committed 
on our coast, the appearance of our cliffs will at 
once testify to their amount. When itis considered, 
that, consistently with geology and even with com- 
mon reason, we are bound to admit that the hills 
and land generally on the shore originally presented 
the same smooth outline, and perfect and continued 
slopes and curvatures offered to the view by the
