Thus left to myself I tried to follow Captain Sinclair’s advice as to the keeping up of my heart, though his talk was far from being of a cheering nature. In my young days, more particularly among the sectaries with whom I had been brought most in contact, a belief in the occasional appearance of the Prince of Darkness, and his interference in bodily form with the affairs of men, was widespread and unquestioning. Philosophers in their own quiet chambers may argue learnedly on the absurdity of such things, but in a dim-lit dungeon, cut off from the world, with the grey gloaming creeping down, and one’s own fate hanging in the balance, it becomes a very different matter. The escape, if the Captain’s story were true, appeared to border upon the miraculous. I examined the walls of the cell very carefully. They were formed of great square stones cunningly fitted together. The thin slit or window was cut through the centre of a single large block. All over, as high as the hand could reach, the face of the walls was covered with letters and legends cut by many generations of captives. The floor was composed of old foot-worn slabs, firmly cemented together. The closest search failed to show any hole or cranny where a rat could have escaped, far less a man. It is a very strange thing, my dears, to sit down in cold blood, and think that the chances are that within a few hours your pulses will have given their last throb, and your soul have sped away upon its final errand. Strange and very awesome! The man who rideth down into the press of the battle with his jaw set and his grip tight upon reign and sword-hilt cannot feel this, for the human mind is such that one emotion will ever push out another. Neither can the man who draws slow and catching breaths upon the bed of deadly sickness be said to have experience of it, for the mind weakened with disease can but submit without examining too closely that which it submits to. When, however, a young and hale man sits alone in quiet, and sees present death hanging over him, he hath such food for thought that, should he survive and live to be grey-headed, his whole life will be marked and altered by those solemn hours, as a stream is changed in its course by some rough bank against which it hath struck. Every little fault and blemish stands out clear in the presence of death, as the dust specks appear when the sunbeam shines into the darkened room. I noted them then, and I have, I trust, noted them ever since.
