apart, leaving an opening as wide as a door.

"'Enter in the name of the Holy Trinity,' said the soldier, 'and
fear nothing.' The student's heart quaked, but he made the sign of
the cross, muttered his Ave Maria, and followed his mysterious guide
into a deep vault cut out of the solid rock under the tower, and
covered with Arabic inscriptions. The soldier pointed to a stone
seat hewn along one side of the vault. 'Behold,' said he, 'my couch
for three hundred years.' The bewildered student tried to force a
joke. 'By the blessed St. Anthony,' said he, 'but you must have
slept soundly, considering the hardness of your couch.'

"'On the contrary, sleep has been a stranger to these eyes;
incessant watchfulness has been my doom. Listen to my lot. I was

"'Once every hundred years, on the festival of St. John, the

and post myself upon the bridge of the Darro, where you met me,
waiting until some one shall arrive who may have power to break this
magic spell. I have hitherto mounted guard there in vain. I walk
