Nothing, half a century ago, more resembled every other carriage gate than the carriage gate of Number 62 Rue Petit-Picpus. This entrance, which usually stood ajar in the most inviting fashion, permitted a view of two things, neither of which have anything very funereal about them,--a courtyard surrounded by walls hung with vines, and the face of a lounging porter. Above the wall, at the bottom of the court, tall trees were visible. When a ray of sunlight enlivened the courtyard, when a glass of wine cheered up the porter, it was difficult to pass Number 62 Little Picpus Street without carrying away a smiling impression of it. Nevertheless, it was a sombre place of which one had had a glimpse.

The threshold smiled; the house prayed and wept.

If one succeeded in passing the porter, which was not easy,-- which was even nearly impossible for every one, for there was an open sesame! which it was necessary to know,--if, the porter once passed, one entered a little vestibule on the right, on which opened a staircase shut in between two walls and so narrow that only one person could ascend it at a time, if one did not allow one's self to be alarmed by a daubing of canary yellow, with a dado of chocolate which clothed this staircase, if one ventured to ascend it, one crossed a first landing, then a second, and arrived on the first story at a corridor where the yellow wash and the chocolate-hued plinth pursued one with a peaceable persistency. Staircase and corridor were lighted by two beautiful windows. The corridor took a turn and became dark. If one doubled this cape, one arrived a few paces further on, in front of a door which was all the more mysterious because it was not fastened. If one opened it, one found one's self in a little chamber about six feet square, tiled, well-scrubbed, clean, cold, and hung with nankin paper with green flowers, at fifteen sous the roll. A white, dull light fell from a large window, with tiny panes, on the left, which usurped the whole width of the room. One gazed about, but saw no one; one listened, one heard neither a footstep nor a human murmur. The walls were bare, the chamber was not furnished; there was not even a chair.

One looked again, and beheld on the wall facing the door a quadrangular hole, about a foot square, with a grating of interlacing iron bars, black, knotted, solid, which formed squares-- I had almost said meshes--of less than an inch and a half in diagonal length. The little green flowers of the nankin paper ran in a calm and orderly manner to those iron bars, without being startled or thrown into confusion by their funereal contact. Supposing that a living being had been so wonderfully thin as to essay an entrance or an exit through the square hole, this grating would have prevented it. It did not allow the passage of the body, but it did allow the passage of the eyes; that is to say, of the mind. This seems to have occurred to them, for it had been re-enforced by a sheet of tin inserted in the wall a little in the rear, and pierced with a thousand holes more microscopic than the holes of a strainer. At the bottom of this plate, an aperture had been pierced exactly similar to the orifice of a letter box. A bit of tape attached to a bell-wire hung at the right of the grated opening.

If the tape was pulled, a bell rang, and one heard a voice very near at hand, which made one start.

"Who is there?" the voice demanded.

It was a woman's voice, a gentle voice, so gentle that it was mournful.

Here, again, there was a magical word which it was necessary to know. If one did not know it, the voice ceased, the wall became silent once more, as though the terrified obscurity of the sepulchre had been on the other side of it.

If one knew the password, the voice resumed, "Enter on the right."

One then perceived on the right, facing the window, a glass door surmounted by a frame glazed an............
