A sentinel watched continually at the outside of his door; others were stationed near enough to lend assistance on a word of alarm; and his window, even if the bars could be forced, was rendered secure by the vigilance of a soldier placed beneath to protect it.

His own strength and address were therefore unavailing; the conviction vexed and mortified him, and he paced his apartment with rapid steps, till his harassed feelings were wrought up to the highest pitch of irritability.
Daylight disappeared, and the evening advanced in gloom and darkness; not a star shone in the heavens, and the moon vainly struggled with the clouds which overshadowed her.

A hollow blast, at intervals, swept across the grated window, then murmured into total silence; the waves rolled sullenly below, and occasionally the measured dash of oars from some passing boat was mingled with their melancholy cadence.

La Tour's meditations were broken by the sentinel entering with a light; and as he placed it on a wooden stand, he lingered a moment, and regarded the prisoner with peculiar attention.

He, however, took no notice of it, except to avert his face more entirely from, what he considered, a gaze of impertinent curiosity.
