Jules Verne,
The Voyages and Adventures of Captain Hatteras…
“ The nature of the ground added much to the fatigue of the journey; North Devon was far from level; they had to cross the Tranter Mountains by almost impassable ravines, struggling against all the fury of the elements. The sledge, men, and dogs had to rest, and more than once despair seized the little band, hardened as it was to the fatigues of a polar journey. But, without their noticing it, these poor men were nearly worn out, physically and morally; they could not support such incessant fatigue for eighteen months with impunity, nor such a succession of hopes and despairs. ”
