Ice? Yes; ice; Hrymir the frost-giant, and no one else. And if you will look at the facts, you will see how ice may have done it. Our friend John Jones’s report of plains and bogs and a lake above makes it quite possible that in the “Ice age” (Glacial Epoch, as the big-word-mongers call it) there was above that cliff a great neve, or snowfield, such as you have seen often in the Alps at the head of each glacier. Over the face of this cliff a glacier has crawled down from that neve, polishing the face of the rock in its descent: but the snow, having no large and deep outlet, has not slid down in a sufficient stream to reach the vale below, and form a glacier of the first order; and has therefore stopped short on the other side of the lake, as a glacier of the second order, which ends in an ice-cliff hanging high up on the mountain side, and kept from further progress by daily melting. If you have ever gone up the Mer de Glace to the Tacul, you saw a magnificent specimen of this sort on your right hand, just opposite the Tacul, in the Glacier de Trelaporte, which comes down from the Aiguille de Charmoz.
This explains our pebble-ridge. The stones which the glacier rubbed off the cliff beneath it it carried forward, slowly but surely, till they saw the light again in the face of the ice-cliff, and dropped out of it under the melting of the summer sun, to form a huge dam across the ravine; till, the “Ice age” past, a more genial climate succeeded, and neve and glacier melted away: but the “moraine” of stones did not, and remains to this day, as the dam which keeps up the waters of the lake.
There is my explanation. If you can find a better, do: but remember always that it must include an answer to—“How did the stones get across the lake?”
Now, reader, we have had no abstruse science here, no long words, not even a microscope or a book: and yet we, as two plain sportsmen, have gone back, or been led back by fact and common sense, into the most awful and sublime depths, into an epos of the destruction and re-creation of a former world.
This is but a single instance; I might give hundreds. This one, nevertheless, may have some effect in awakening you to the boundless world of wonders which is all around you, and make you ask yourself seriously, “What branch of Natural History shall I begin to investigate, if it be but for a few weeks, this summer?”
To which I answer, Try “the Wonders of the Shore.” There are along every sea-beach more strange things to be seen, and those to be seen easily, than in any other field of observation which you will find in these islands. And on the shore only will you have the enjoyment of finding new species, of adding your mite to the treasures of science.
For not only the English ferns, but the natural history of all our land species, are now well-nigh exhausted. Our home botanists and ornithologists are spending their time now, perforce, in verifying a few obscure species, and bemoaning themselves, like Alexander, that there are no more worlds left to conquer. For the geologist, indeed, and the entomologist, especially in the remoter districts, much remains to be done, but only at a heavy outlay of time, labour, and study; and the dilettante (and it is for dilettanti, like myself, that I principally write) must be content to tread in the tracks of greater men who have preceded him, and accept at second or third hand their foregone conclusions.
But this is most unsatisfactory; for in giving up discovery, one gives up one of the highest enjoyments of Natural History. There is a mysterious delight in the discovery of a new species, akin to that of seeing for the first time, in their native haunts, plants or animals of which one has till then only read. Some, surely, who read these pages have experienced that latter delight; and, though they might find it hard to define whence the pleasure arose, know well that it was a solid pleasure, the memory of which they would not give up for hard cash. Some, surely, can recollect, at their first sight of the Alpine Soldanella, the Rhododendron, or the black Orchis, growing upon the edge of the eternal snow, a thrill of emotion not unmixed with awe; a sense that they were, as it were, brought face to face with the creatures of another world; that Nature was independent of them, not merely they of her; that trees were not merely made to build their houses, or herbs to feed their cattle, as they looked on those wild gardens amid the wreaths of the untrodden snow, which had lifted their gay flowers to the sun year after year since the foundation of the world, taking no heed of man, and all the coil which he keeps in the valleys far below.
And even, to take a simpler instance, there are those who will excuse, or even approve of, a writer for saying that, among the memories of a month’s eventful tour, those which stand out as beacon-points, those round which all the others group themselves, are the first wolf-track by the road-side in the Kyllwald; the first sight of the blue and green Roller-birds, walking behind the plough like rooks in the tobacco-fields of Wittlich; the first ball of Olivine scraped out of the volcanic slag-heaps of the Dreisser-Weiher; the first pair of the Lesser Bustard flushed upon the downs of the Mosel-kopf; the first sight of the cloud of white Ephemeræ, fluttering in the dusk like a summer snowstorm between us and the black cliffs of the Rheinstein, while the broad Rhine beneath flashed blood-red in the blaze of the lightning and the fires of the Mausenthurm—a lurid Acheron above which seemed to hover ten thousand unburied ghosts; and last, but not least, on the lip of the vast Mosel-kopf crater—just above the point where the weight of the fiery lake has burst the side of the great slag-cup, and rushed forth between two cliffs of clink-stone across the downs, in a clanging stream of fire, damming up rivulets, and blasting its path through forests, far away toward the valley of the Moselle—the sight of an object for which was forgotten for the moment that battle-field of the Titans at our feet, and the glorious panorama, Hundsruck and Taunus, Siebengebirge and Ardennes, and all the crater peaks around; and which was—smile not, reader—our first yellow foxglove.
But what is even this to the delight of finding a new species?—of rescuing (as it seems to you) one more thought of the Divine mind from Hela, and the realms of the unknown, unclassified, uncomprehended? As it seems to you: though in reality it only seems so, in a world wherein not a sparrow falls to the ground unnoticed by our Father who is in heaven.
