Emile was a bold fellow, endowed with a large share of coolness and energy. His mind was made up in a moment, and mentally thanking the individual, whoever he was, who was sparing him the long and fatiguing labour which he did not know how to bring to a successful termination, he quickly placed himself in concealment in a corner of the gallery, placed his lantern on the ground near him, taking care to cover it with his hat, so that its light might not be perceived. Seizing a pistol in each hand, to be ready for anything, he waited with his eyes fixed on the stone, which, owing to the numerous fissures in the walls of the gallery, he could easily distinguish—a prey to a strange emotion, which caused his heart to beat violently, and his blood to rush to his brain.

His watching was not long. Scarcely had he concealed himself before the stone was detached and rolled on the ground, and a man, holding in his hand a carbine, the barrel of which was still smoking, quickly entered the cavern.

The man leant forward towards the aperture, appeared to listen for a few seconds, and then stood up, murmuring loud enough for the young man to hear him.

"They come, but too late; the tiger has now escaped."

And skilfully aiding himself with the barrel of the carbine, as with a lever, he rapidly replaced the stone in its previous position.

"Search, search, perros malditos," said the unknown, with an ironical sneer, "I do not fear you now."

And with the greatest coolness he proceeded to reload his gun; but the painter did not give him time to do so. Rushing from his concealment, and removing the hat which covered his lantern, he stood face to face with the unknown, and, presenting his pistols:

"Who are you? What do you want?" he demanded. The unknown made a movement of surprise and flight, stepped back apace, and letting fall his gun:

"Eh! What is this?" cried he; "Am I, then, betrayed?"

"Betrayed!" repeated the Frenchman, prudently placing his foot on the carbine; "The expression seems to me rather strange from your mouth, Señor; especially after the manner in which you have introduced yourself here."
