“ I am not aware that any authority has fixed the exact degree of steepness at which it becomes impossible to use the ice axe with both hands, but, whatever portion of a right angle the limit may be, Mummery very soon reached it, and commenced excavating with his right hand caves in the ice, each with an internal lateral recess by which to support his weight with his left. Slingsby and I, meanwhile possessing our souls in patience, stood in our respective steps, as on a ladder, and watched his steady progress with admiration, so far as permitted us by the falling ice dislodged by the axe. ”
