Usage examples of "hog's back".
The cave opened out from the hillside, and beyond its mouth, half filling the deep ravine that ran below it, was a heap of earth and slag, a huge hog's back, along which ran a wheelbarrow track to reach the dump of mine tailings at its end.
Up this ice climbed de Garcia, and the task is not of the easiest, even for one of untroubled mind, for a man must step from crack to crack or needle to needle of rough ice, that stand upon the smooth surface like the bristles on a hog's back, and woe to him if one break or if he slip, for then, as he falls, very shortly the flesh will be filed from his bones by the thousands of sword-like points over which he must pass in his descent towards the snow.
Its top sharpened presently into a hog's back, then dropped steeply to deep water, where the ridge had been broken and split by the sea.
