Having thus worked out a most excellent route—assuming that the eye of faith was to be depended on—we determined to put it into execution. Accordingly, on the 1st of August, 1881, we assembled in the salon of the Montenvers Hotel at 1 a.m. Burgener, unluckily, proved to be very unwell, and had to be dosed with chartreuse and brandy before he could be got under weigh. Somewhat delayed by this, it was 2 a.m. before we started. We spent the rest of the night miserably floundering amongst endless stones and moraine-choked crevasses.
