Important discoveries have been made within a short time, showing that certain animal tribes had their origin much farther back than was at first supposed. A few years ago, reptiles were believed to be the highest type of life that existed during the era of the new red sand-stone.
This creek is the most steep, rapid, and dangerous on the road, having no bridge and no properly defined crossing-place or ford, except the natural rocks about. The bottom is of red sand-stone and rocks of the same description abut from the sides of the creek, and appear to abound in the neighbourhood; and all along the plains here and there are large fragments of sand and lime-stone rocks.
M. de Carosi describes very systematically the generation of silex, calcedony, onyx, and quartz, in calcareous earth, marl, gypsum, sand-stone, and also what he terms terre glaise, ou de l'Argile. It is in this last that we find a perfect analogy with what is so frequent in this country of Scotland.
The floor, I recollect, was very uneven and strewed about with big stones, while the roof was arched over in the red sand-stone. The encroachment of the sea upon the Wirral shore has been very gradual, but regular, for many years. Within the memory of man the sea has made an inroad of nearly, if not quite, a mile from its former high-water mark.
Another assessment of $50 to enable the Superintendent to proceed to Russia and Spain and examine into the workings of the quicksilver mines there, and also a general commission to the gifted and scientific Pillageman to examine into the various component parts of quicksilver, and report if it could not be manufactured from ordinary sand-stone by steam or electricity, speedily brought the other stockholders to their senses.
The strata there, as in Berwickshire, which is their continuation to the east, are remarkably horizontal for Scotland; and they consist of alternated beds of sand-stone and marl, or argillaceous and micaceous strata. Chance, however, discovered to me what I could not have expected or foreseen.
With occasional and partial interruption, however, the sand-stone formation continues to an abrupt pass, from which the traveller descends to the county of Argyle. This pass is extremely abrupt, and is covered with glaucus, the low scrub I have noticed as common to the sand-stone formation.
Now, shall we suppose those strata of sand-stone to have been formed in their place, and to have reached no farther eastward into the sea? It is unsupposable. Or, shall we conceive that the sea, which has made such depredations in land composed of much more solid materials, had spared this, and had not wasted much more than that now pointed out by the ruins which remain?
A photograph of one of them is like one of those fossilized sea-beaches where the raindrops have left their marks, and the shellfish the grooves in which they crawled, and the wading birds the divergent lines of their foot-prints, tears, cares, griefs, once vanishing as impressions from the sand, now fixed as the vestiges in the sand-stone.
In the bottom of those rivulets the sand-stone and marly strata appear pretty much inclined, rising towards the schistus country. The two burns unite before they come to the shore; and it is about midway between this junction and the bridges which are thrown over those two hollows, that the junction is to be found.
