side, the cliff itself, is - why, the whole cliff is composed of
the very same stone as the pebble ridge.

Now, my good friend, how did these pebbles get three hundred yards
across the lake? Hundreds of tons, some of them three feet long:
who carried them across? The old Cymry were not likely to amuse
themselves by making such a breakwater up here in No-man's-land,
two thousand feet above the sea: but somebody or something must
have carried them; for stones do not fly, nor swim either.

Shot out of a volcano? As you seem determined to have a prodigy,
it may as well be a sufficiently huge one.

Well - these stones lie altogether; and a volcano would have hardly
made so compact a shot, not being in the habit of using Eley's wire
cartridges. Our next hope of a solution lies in John Jones, who
carried up the coracle. Hail him, and ask him what is on the top
of that cliff . . . So, "Plainshe and pogshe, and another Llyn."
Very good. Now, does it not strike you that this whole cliff has a
remarkably smooth and plastered look, like a hare's run up an
earthbank? And do you not see that it is polished thus only over
the lake? that as soon as the cliff abuts on the downs right and
left, it forms pinnacles, caves, broken angular boulders? Syenite
usually does so in our damp climate, from the "weathering" effect
of frost and rain: why has it not done so over the lake? On that
part something (giants perhaps) has been scrambling up or down on a
very large scale, and so rubbed off every corner which was inclined
to come away, till the solid core of the rock was bared. And may
not those mysterious giants have had a hand in carrying the stones
across the lake? . . . Really, I am not altogether jesting. Think
