The sentinel exchanged a few whispered words with Montbar, who seemed, by fulfilling the duties of leader, desirous of leaving Morgan entirely to his thoughts. Then, as his watch was probably not over, the bandit climbed the oak again, and was soon so completely blended with the body of the tree that those he had left might have looked for him in vain in that aerial bastion. The glade became narrower as they neared the entrance to the grotto. Montbar reached it first, and from a hiding-place known to him he took a flint, a steel, some tinder, matches, and a torch. The sparks flew, the tinder caught fire, the match cast a quivering bluish flame, to which succeeded the crackling, resinous flames of the torch. Three or four paths were then visible. Montbar took one without hesitation. The path sank, winding into the earth, and turned back upon itself, as if the young men were retracing their steps underground, along the path that had brought them. It was evident that they were following the windings of an ancient quarry, probably the one from which were built, nineteen hundred years earlier, the three Roman towns which are now mere villages, and Cæsar’s camp which overlooked them. At intervals this subterraneous path was cut entirely across by a deep ditch, impassable except with the aid of a plank, that could, with a kick, be precipitated into the hollow beneath. Also, from place to place, breastworks could still be seen, behind which men could intrench themselves and fire without exposing their persons to the sight or fire of the enemy. Finally, at five hundred yards from the entrance, a barricade of the height of a man presented a final obstacle to those who sought to enter a circular space in which ten or a dozen men were now seated or lying around, some reading, others playing cards. Neither the readers nor the players moved at the noise made by the new-comers, or at the gleam of their light playing upon the walls of the quarry, so certain were they that none but friends could reach this spot, guarded as it was. For the rest, the scene of this encampment was extremely picturesque; wax candles were burning in profusion (the Companions of Jehu were too aristocratic to make use of any other light) and cast their reflection upon stands of arms of all kinds, among which double-barrelled muskets and pistols held first place. Foils and masks were hanging here and there upon the walls; several musical instruments were lying about, and a few mirrors in gilt frames proclaimed the fact that dress was a pastime by no means unappreciated by the strange inhabitants of that subterranean dwelling. They all seemed as tranquil as though the news which had drawn Morgan from Amélie’s arms was unknown to them, or considered of no importance.
