They were glad enough to rest and wipe their brows as they stood by the rough block, and upon which they found they could easily climb; but there was nothing more to see than at their former visit, save that the rocks looked far more rough, both at the torrent-like entrance and the narrow opening on their right, while even from the height at which they stood it was plain to see that the circular cove was in a violent state of ebullition.
But here, close in, was the slope which ran down towards the sea--very similar in character to that by which they had ascended, only that it was, as it were, chopped off short.
