We soon took to the rocks, and found them, as the charcoal-burner had promised, sufficiently stiff work. Colonel (now General) Dufour visited the Schafloch with a party of officers in 1822, and he describes[57] the path as a dangerous one, so much so that several of the gallant members of his party could not reach the cave: he uses rather large words about the precipices, and it is a matter of observation that military service on the Continent tends to induce a habit of body which is not the most suitable for doubtful climbing. The mountain seemed to be composed, in this part, of horizontal layers of crumbling shale, with a layer now and then of stone, about the thickness of an ordinary house-tile. The stone layers project from the looser masonry, and afford an excellent foot-hold; but a slip might be unpleasant. Every one who has done even a small amount of climbing has met with an abundance of places where 'a slip would be certain death,' as people are so fond of saying; but equally he has discovered that a slip is the last thing he thinks of making in such situations. Christian had told me that if I had the slightest tendency to _Schwindelkopf_, I must not go by the improvised route; but it proved that there were really no precipices at all, much less any of sufficient magnitude to turn an ordinary head dizzy. He chose these rocks as the text for a long sermon on the necessity for great caution when we should arrive at the cave, telling of an Englishman who had tried to visit it two years before, and had cut his knee so badly with his guide's axe that he had to be carried down the mountain to Gonten, and thence to the steamer for Thun, in which town he lay for many weeks in the hands of the German doctor; this last assertion being by no means incredible. Also, of a native who attempted the cave alone, and, making one false step near the top of a fall of ice, slipped down and down almost for ever, and finally landed with broken limbs on a floor of ice, where he was found, two days after, frozen stiff, but still alive.
