“The interior of the cave, which here rose very high, was illuminated by torches made of pine-tree, which emitted a bright and bickering light, attended by a strong though not unpleasant odour. Their light was assisted by the red glare of a large charcoal fire, round which were seated five or six armed Highlanders, while others were indistinctly seen couched on their plaids, in the more remote recesses of the cavern.”
