"It was in the church of St. Prassede. St. Prassede, the signor knows, was one of the daughters of the senator Pudens mentioned by St. Paul as sending his greetings to Timothy. The present church stands on the site of the very house once inhabited by this Christian family, and in the dark crypt under the high altar there is a walled-up doorway with the sign of the cross upon it. The crypt was originally the cellar of the ancient house, into which debouched one of the secret entrances to the Catacombs: at one extremity of the crypt is the doorway in question, now strongly built up, with the cross impressed in its superficial stucco. "For many centuries the subterranean excavations behind the crypt have been haunted by the Evil One and his coadjutors, who break forth from time to time in unearthly noises, racings, scamperings, moanings and yellings, and scarcely a man, woman or child in the vicinity but has heard them with their own veritable ears. Many special services of exorcism have been performed in the church above to meet the occasions as they might arise, but with no permanent effect. And, signor, notwithstanding the cloud of witnesses that can testify to these supernatural sounds, the city contains sceptics, and none more determined than the learned Father Xavier of the Holy Propaganda. "The day of the miracle that I am about to tell you of was a dark, wet Thursday in November, when my wife Teresina and myself attended high mass at St. Prassede, in honor of Teresina's festa.

Gasps, yellings, scamperings, and then a cessation, and again a repetition of the same unearthly sounds with increased vehemence. Sometimes they would seem to recede till they died away in the distance, and then come rushing as if a whole legion of the enemy were close at hand. From the body of the church the crypt is approached by an open passage down a wide flight of steps immediately in front of the high altar, and the walled door, as well as the whole of the crypt, can be distinctly seen from the top of the steps. When the mysterious noises were first heard most of the congregation had retreated precipitately to the doors, but some of the more pious or venturesome--among whom were Teresina and myself--had remained, and were leaning over the balusters while the padre descended with his attendants to perform the special service appointed for the occasion. The exorcism took effect, for the noises, from being very uproarious, suddenly ceased altogether, and the arch-fiend seemed pacified, if not utterly routed, until at the close of the service, a bell was rung as appointed in the office. The sound of this bell had the effect of increasing the demoniac uproar to such a degree that the padre officiating was fain to hurry through the rest of the service as best he could and beat a precipitate retreat, with the acolytes, bells
