"You are a baby. Now I am off, and do you wait for me here: swear not to leave this place till my return."

"I swear it."

"Good: I am going to work for you, so hope I shall return soon."

And giving him a last wave of the hand, the adventurer went off by a side gallery.

The young man remained pensive so long as the sound of his friend's retiring footsteps reached him, then he fell back on the bed of furs, murmuring in a low voice, "He told me to wait."

We will leave Dominique plunged in those reflections which, judging from the expression of his face, must have been agreeable, and follow don Jaime on his adventurous expedition. As the vault was situated about half a league from the town, don Jaime had that distance to go underground before he found himself in Puebla. But this long walk did not appear at all to alarm him: he proceeded at a round pace along the gallery into which sufficient light penetrated by invisible interstices, for him to be able to guide himself in the countless windings he was forced to make. He walked thus for about three parts of an hour, and at length reached the foot of a staircase, consisting of fifteen steps.

The adventurer stopped a moment to draw breath, and then went up. When he reached the top of the steps, he sought for a spring, which he soon found, and pressed his finger on it. Immediately an enormous stone became detached from the wall, moved noiselessly on invisible hinges, and displayed a wide passage. Don Jaime stepped out and thrust back the stone, which immediately resumed its first position in so perfect a manner, that it was impossible, even with the most earnest attention, to perceive the slightest crack or solution of continuity in the wall.

Don Jaime looked searchingly round him: he was alone. The spot where he was was a chapel of the cathedral of Puebla. The secret door through which the adventurer had passed opened on a corner of this chapel, and was concealed by a confessional. These precautions were carefully taken, and there was no risk of a discovery. Don Jaime left the church and found himself on the Plaza Mayor. It was about midday, the hour of the siesta, and the square was almost deserted. The adventurer pulled the hood over his eyes, hid his hands in his cuffs, and with his head hanging on his chest, and with a calm and contemplative step he crossed the square and entered one of the streets that ran from it.

Oliver thus reached the gate of a pretty house, standing in its own grounds, and which seemed to rise from the centre of a bouquet of orange and pomegranate trees. As this gate was only on the hasp, the adventurer pushed it, went in and closed the gate again after him. He then found himself on the sanded walk that led to the door of the house, which was raised by a few steps, and covered by a large verandah in the Mexican fashion. Oliver looked suspiciously around him, but the garden was deserted. He advanced; but instead of proceeding toward the house he struck into a sidewalk, and after a few turns found himself facing a door apparently belonging to the offices.

On reaching this spot Oliver took a silver whistle hanging round his neck by a thin gold chain, raised it to his lips, and produced a sweet and peculiarly modulated sound. Almost immediately a similar whistle was heard from the interior, the door opened, and a man appeared. The adventurer made him a Masonic sign, to which the other replied, and followed him into the house. Without speaking, this man guided him through several apartments till he reached a door which he opened to let the adventurer pass through, while he remained behind.
