Expecting fully that they would not persevere beyond a few minutes longer, I called out to Tyndall to know how soon they meant to be back. 'In an hour and a half,' he replied, whether in jest or earnest, and they disappeared round a projecting corner. A sudden qualm seized me, and for a few minutes I felt extremely uncomfortable: what if the ascent should suddenly become easier, and they should go on, and reach the top without me? I thought of summoning Carrel, and pursuing them; but the worthy man sat quietly, and seemed to have had enough of it. My suspense, however, was not long: after two or three minutes the clatter, which had never entirely ceased, became louder, and their forms again appeared: they were evidently descending. In fact, Bennen had at length turned, and said to Tyndall, 'Ich denke die Zeit ist zu kurz.' I was glad that he had gone on as long as he chose, and not been turned back on my responsibility. They had found one part of this last ascent the worst of any, but the way was open thenceforward to the farthest visible point, which can be no long way below the actual top.
It was now just about mid-day, and ample time for the descent, in all probability, was before us; but we resolved not to halt for any length of time till we should reach the gap. Descending, unlike ascending, is generally not so bad as it seems; but in some places here only one can advance at a time, the other carefully holding the rope. 'Tenez fortement, Carrel, tenez,' is constantly impressed on the man who brings up the rear. 'Splendid practice for us, this,' exclaims Tyndall exultingly, as each successive difficulty is overcome. At length we reach a place whence no egress is possible; we look in vain for traces of the way we had come: it is our friend the ice-coated chimney. Bennen gets down first, in the same mysterious fashion as he got up, and assists us down; presently a shout is heard behind; Carrel is attempting to get down by himself, and has stuck fast; Bennen has to extricate him. We are now getting rapidly lower; soon the difficulties diminish; our gap appears in sight, and once more we reach the broad granite slab beside the narrow col, and breathe more freely.
