still remain in the holes; they and the walls of the holes are worn smooth by the long-continued chafing which they gave each other in those old days.  It took a mighty force to churn these big lumps of stone around in that vigorous way.  The neighboring country had a very different shape, at that time—­the valleys have risen up and become hills, since, and the hills have become valleys.  The boulders discovered in the pots had traveled a great distance, for there is no rock like them nearer than the distant Rhone Glacier.

For some days we were content to enjoy looking at the blue lake Lucerne and at the piled-up masses of snow-mountains that border it all around—­an enticing spectacle, this last, for there is a strange and fascinating beauty and charm about a majestic snow-peak with the sun blazing upon it or the moonlight softly enriching it—­but finally we concluded to try a bit of excursioning around on a steamboat, and a dash on foot at the Rigi.  Very well, we had a delightful trip to Fluelen, on a breezy, sunny day.  Everybody sat on the upper deck, on benches, under an awning; everybody talked, laughed, and exclaimed at the wonder scenery; in truth, a trip on that lake is almost the perfection of pleasuring.  The mountains were a never-ceasing marvel.  Sometimes they rose straight up out of the lake, and towered aloft and overshadowed our pygmy steamer with their prodigious bulk in the most impressive way.  Not snow-clad mountains, these, yet they climbed high enough toward the sky to meet the clouds and veil their foreheads in them.  They were not barren and repulsive, but clothed in green, and restful and pleasant to the eye.  And they were so almost straight-up-and-down, sometimes, that one could not imagine a man being able to keep his footing upon such a surface, yet there are paths, and the Swiss people go up and down them every day.

Sometimes one of these monster precipices had the slight inclination of the huge ship-houses in dockyards —­then high aloft, toward the sky, it took a little stronger inclination, like that of a mansard roof—­and perched on this dizzy mansard one’s eye detected little things like martin boxes, and presently perceived that these were the dwellings of peasants—­an airy place for a home, truly.  And suppose a peasant should walk in his sleep, or his child should fall out of the front yard?—­the friends would have a tedious long journey down out of those cloud-heights before they found the remains.  And yet those far-away homes looked ever so seductive, they were so remote from the troubled world, they dozed in such an atmosphere of peace and dreams—­surely no one who has learned to live up there would ever want to live on a meaner level.

We swept through the prettiest little curving arms of the lake, among these colossal green walls, enjoying new delights, always, as the stately panorama unfolded itself before us and rerolled and hid itself behind us; and now and then we had the thrilling surprise of bursting suddenly upon a tremendous white mass like the distant and dominating Jungfrau, or some kindred giant, looming head and shoulders above a tumbled waste of lesser Alps.
