HAL.—We will arrange a dinner of this kind in England, and by means of it follow the analogies of salt and fresh water fishes. But the time for our parting is almost arrived.—Let us drink a glass each of this old wine of the Danube to our next happy meeting, and go and take a last look of the Fall of Traun, whilst our carriages are preparing. [_They walk to the rock above the Fall of the Traun._] HAL.—See, the cataract is now in great beauty; the river above is coloured by the setting sun, and the glow of the rosy light on the upper stream is beautifully and wonderfully contrasted with the tints of the cataract below. Have you ever seen any thing so fine? POIET.—The lights are beautiful; but I have certainly seen a finer combination of features in the Fall of the Velino, at Terni, though that water is not clear; but, even with this defect, it is certainly the most perfect of European falls. This cascade of the Traun, though not so elevated as that of Terni, and not so large as that of Schaffhausen, yet, from its perfect clearness, and the harmony of the surrounding objects, ranks high, as to picturesque effect, amongst the waterfalls of Europe; and the wonderful transparency of its pale-green water gives it a peculiar charm in my eyes, enhanced as it is now by the light of the glowing western sky; and the tints of the quadrant iris on its spray are not brighter than those of its stream and foam. ORN.—We have now followed this water at least thirty miles, and wherever we have seen it, it has always displayed the same characters of clearness and rapidity—of green stream and white foam; and we have traced it from the snowy mountains of Styria to the plains of Upper Austria, where it serves to purify the darker Danube. How is it, that it has preserved its transparency, though so many of its tributary streams have been foul, either from the thunder storm, or from the sudden melting of snows? HAL.—The three small lakes and the two larger ones, which are in fact its reservoirs, are the cause of this. The Gründtl See furnishes its principal stream, and this lake is fed by two others—Töplitz See and Lahngen See; and the tributary streams, which unite at Aussee, from Alten Aussee and Oden See, though one is blue and the other yellow, yet combine to give a tint, which is nearly the same as that from the stream of the Gründtl See, and which the river retains throughout its course Yet I have seen even this river very foul, but only in a part of its course, below Ischel. I was once at that place, when the thunder storm of a night having washed the dust of the roads into the river, it was extremely turbid from Ischel to the Traun See. It rendered the upper part of this large lake coloured; but, notwithstanding this, the river came from the lower part of it perfectly clear, and I caught fish in it there with a fly, which, at its entrance into the lake was quite impossible.
