But with devilish perversity, an immense fog-horn sent forth a heavy blast seaward precisely at the moments he raised his voice.

No matter how far apart or how near he planned the intervals, he was bound to coincide with the deafening horn.

At last in despair he desisted in his efforts, and the monster horn, with hoarse mockery, continued its grewsome noises at dismal intervals, until one, more stentorian than the others, caused the very tempest to hush, and Robert awoke to discover Gratz the cause of his fictitious misery, sleeping upon the cot near the foot of his bed, emitting a series of snores which had managed to communicate their odious telepathy to his slumbering consciousness.
