beauty; and nowhere is this more strikingly the case than in the province of Moray, where it leans against the granitic gneiss of the uplands, and slopes towards the sea in long plains of various fertility, deep and rich, as in the neighborhood of Elgin, or singularly bleak and unproductive, as in the farfamed “heath near Forres." Let us select the scene where

quite as conclusive as the nature of the case admits, that when they ceased to be seen there it would have been vain to have looked for them any where else. There is a cluster of turf-built cottages grouped on the southern side of the ravine; a few scattered knolls, and a long, partially wooded hollow, that seems a sort of covered way leading to the recesses of the dell, interpose between them and the nearer edge, and the hill rises behind. On a Sabbath morning, nearly sixty years ago, the inmates of this little hamlet had all gone to church, all except a herd-boy and a little girl, his sister, who were lounging beside one of the cottages; when, just as the shadow of the garden dial had fallen on the line of noon, they saw a long cavalcade ascending out of the ravine through the wooded hollow. It winded among the knolls and bushes; and, turning round the northern gable of the cottage beside which the sole spectators of the scene were stationed, began to ascend the eminence towards the south. The horses were shaggy, diminutive things, speckled dun and gray; the riders, stunted, misgrown, ugly creatures, attired in antique jerkins of plaid, long gray cloaks, and little red caps, from under which their wild, uncombed locks shot out over their cheeks and foreheads. The boy and his sister stood gazing in utter dismay and astonishment, as rider after rider, each one more uncouth and dwarfish than the one that had preceded it, passed the cottage and disappeared among the brushwood, which at that period covered the hill, until at length the entire rout, except the last rider, who lingered a few yards behind the others, had gone by. "What are ye, little mannie? and where are ye going?" inquired the boy, his curiosity getting the better of his fears and his prudence. "Not of the race of Adam," said the creature, turning for a moment in his saddle; "the People of Peace shall never more be seen in Scotland."

the Findhorn, after hurrying over ridge and shallow, amid combinations of rock and wood, wildly picturesque as any the kingdom affords, enters on the lower country, with a course less headlong, through a vast trench scooped in the pale red sandstone of the upper formation. For miles above the junction of the newer and older rocks the river has been toiling in a narrow and uneven channel, between two upright walls of hard gray gneiss, thickly traversed, in every complexity of pattern, by veins of a light red, large grained granite. The gneiss abruptly terminates, but not so the wall of precipices. A lofty front of gneiss is joined to a lofty front of sandstone, like the front walls of two adjoining houses; and the broken and uptilted strata of the softer stone show that the older and harder rocks must have invaded it from below. A little farther down the stream, the strata assume what seems, in a short extent of frontage, a horizontal position, like courses of ashlar in a building, but which, when viewed in the range, is found to incline at a low angle towards the distant sea. Here, as in many other localities, the young geologist must guard against the conclusion, that the rock is necessarily low in the geological scale which he finds resting against the gneiss. The gneiss, occupying a very different place from that on which it was originally formed, has been thrust into close neighborhood with widely separated formations. The great conglomerate base of the system rests over it in Orkney, Caithness, Ross, Cromarty, and Inverness; and there is no trace of what should be the intervening grauwacke. The upper formation of the system leans upon it here. We find the Lower Lias uptilted against it at the Hill of Eathie-the great Oolite on the eastern coast of Sutherland; and as the flints and chalk fossils of Banff and Aberdeen are found lying immediately over it in these counties,

it is probable that the denuded members of the Cretaceous group once rested upon it there. The fact that a deposit should be found lying in contact with the gneiss, furnishes no argument for the great antiquity or the fundamental character of that deposit; and it were well that the geologist who sets himself to estimate the depth of the Old Red Sandstone, or the succession of its various formations, should keep the circumstance in view. That may be in reality but a small and upper portion of the system which he finds bounded by the gneiss on its under side, and by the diluvium on its upper.

We stand on a wooded eminence, that sinks perpendicularly into the river on the left, in a mural precipice, and descends with a billowy swell into the broad, fertile plain in front, as if the uplands were breaking in one vast wave upon the low country. There is a patch of meadow on the opposite side of the stream, shaded by a group of ancient trees, gnarled and mossy, and with half their topmost branches Idead and white as the bones of a skeleton. We look down upon them from an elevation so commanding, that their uppermost twigs seem on well nigh the same level with their interlaced and twisted roots, washed bare on the bank edge by the winter floods. A colony of herons has built from time immemorial among the branches. There are trees so laden with nests that the boughs bend earthwards on every side, like the boughs of orchard trees in autumn; and the bleached and feathered masses which they bear the cradles of succeeding generations- glitter gray through the foliage in continuous groups, as if each tree bore on its single head all the wigs of the Court of Session. The solitude is busy with the occupations and enjoyments of instinct. The birds, tall and stately, stand by troops in the shallows, or wade warily, as the fish glance by, to the edge of the current, or rising, with

the slow flap of wing and sharp creak peculiar to the tribe, drop suddenly into their nests. The great forest of Darnaway stretches beyond, feathering a thousand knolls, that reflect a colder and grayer tint as they recede, and lessen, and present on the horizon a billowy line of blue. The river brawls along under pale red cliffs, wooded a-top. It is through a vast burial-yard that it has cut its way- a field of the dead so ancient, that the sepulchres of Thebes and Luxor are but of the present day in comparison resting-places for the recently departed, whose funerals are but just over. These mouldering strata are charged with remains, scattered and detached as those of a churchyard, but not less entire in their parts occipital bones, jaws, teeth, spines, scales — the dust and rubbish of a departed creation. The cliffs sink as the plain flattens, and green, sloping banks of diluvium take their place; but they again rise in the middle distance into an abrupt and lofty promontory, that, stretching like an immense rib athwart the level country, projects far into the stream, and gives an angular inflection to its course. There ascends from the apex a thin, blue column of smoke - that of a lime-kiln. That ridge and promontory are composed of the thick limestone band, which, in Moray as in Fife, separates the pale red from the pale yellow beds of the Upper Old Red Sandstone; and the flattened tracts on both sides show how much better it has resisted the denuding agencies than either the yellow strata that rests over it, or the pale red strata which it overlies.

We may

"THERE are only two different aspects," says Dr. Thomas Brown," in which matter can be viewed. consider it simply as it exists in space, or as it exists in time. As it exists in space we inquire into its composition, or, in other words, endeavor to discover what are the elementary bodies that coexist in the space which it occupies; as it exists in time, we inquire into its susceptibilities or its powers, or, in other words, endeavor to trace all the various changes which have already passed over it, or of which it may yet become the subject."

Hitherto I have very much restricted myself to the consideration of the Old Red Sandstone as it exists in space-to the consideration of it as we now find it. I shall now attempt presenting it to the reader as it existed in time—during the succeeding periods of its formation, and when its existences lived and moved as the denizens of primeval oceans. It is one thing to describe the appearance of a forsaken and des
