the schistus in the lower beds of sand-stone;
here a mountain of water-worn schisti, imbedded in a red earth and
consolidated, presented itself to our view. It was evident that the
schisti mountains, from whence those fragments had come, had been prior
to this secondary mass; but here is a secondary mountain equal in height
to the primary, or schisti mountains, at the basis of which we had seen
the strata superinduced on the shore. Still, however, every thing here
is formed upon the same principle, and nothing here is altered except
the scale on which the operation had been performed.

Upon the coast, we have but a specimen of the pudding-stone; most of
the fragments had their angles entire; and few of them are rounded by
attrition. Here, on the contrary, the mountain is one pudding-stone;
and most of the fragments are stones much rounded by attrition. But the
difference is only in degree, and not in kind; the stones are the same,
and the nature of the composition similar. Had we seen the mass of which
this mountain is only a relict, (having been degraded by the hands of
time), we should have found this pudding-stone at the bottom of
our sand-stone strata; could we have penetrated below this mass of
pudding-stone, we should have found our schistus which we left on the
shore at St. Helens and in the Tour burn. In Tiviotdale the vertical
schisti are covered with a bed of pudding-stone, the gravel of which had
been much worn by attrition, but the thickness of that bed is small;
here again the wearing operation has been great, and the quantity of
those materials even more than in proportion to those operations. We
returned perfectly satisfied; and Sir James Hall is to pursue this
subject farther when he shall be in those mountains shooting muir game.

We had now only one object more to pursue; this was to examine the south
side of those mountains of Lammermuir upon the sea shore, in order
to see the junction of the primary schistus with the coal strata
of Berwickshire. Mr Hall was to meet us at the Press, and we were
afterwards to go with him to Whitehall. We met accordingly; but the
weather was rainy; and we went directly to Whitehall. I had often seen
the pudding-stone in great masse; in the banks of the Whiteader, as
it comes out of the mountains, but then I had not seen its connection
neither, on the one hand, with the schisti, nor, on the other, with the
sand-stone strata. We knew that at Lammerton upon the sea coast t
