After more than an hour's ride among the mountains, they came to a lake formed by the damming up of a river by a tremendous stream of lava which had flowed from the side of a lofty volcanic mountain. The lake was of some extent, and its borders were in places fringed by trees, while the shallower parts were full of reeds, bulrushes, and aquatic plants. Marcelline now took a hawk from one of the falconers, and a heron shortly afterwards rising from the reeds, she quickly unhooded the hawk, and cast it off. On perceiving its danger, the heron flew swiftly upwards, followed with equal swiftness by the hawk, and to such a height did they soar, that they looked like specks, and eventually almost vanished from sight. When they reappeared, the hawk was uppermost, and soon stooped upon her prey, and ere another minute the heron fell dead within a few yards of Marcelline. A bittern was next roused, but the party were prevented from continuing the sport by the appearance of a troop of horsemen coming from the direction of the chateau. No doubt could be entertained that this troop, which consisted of a dozen men and a captain, were in pursuit of the Constable. There was no time for deliberation, but Marcelline was equal to the emergency. “Ride on with the prince,” she said to her brother. “Let the Seigneur Pomperant go with me. They will take him for the Constable. We can make our way across the mountains to the Château de Lallières. If you can baffle pursuit, you will find us there.” To this bold proposition D'Herment at once agreed, and the courageous damsel, calling upon Pomperant to follow her, dashed up the rugged side of the mountain. At the same moment, D'Herment, followed by Bourbon and the falconers, galloped off along a road which skirted the banks of the lake. The movements of the parties were of course descried by Captain Florae, the leader of the troop. As had been foreseen by Marcelline, he mistook Pomperaût for Bourbon, and started in pursuit with a couple of men, despatching the rest of the troop after the other fugitives, While mounting the hill, Marcelline and her companion remained in sight of their pursuers, but soon after gaining the summit they were lost to view. On reaching the same point, Florae found that they were descending a precipitous road into the valley on the opposite side of the mountain, and, notwithstanding the danger of the course, he unhesitatingly followed with his men, and reached the valley in safety. The chase continued for more than a league along a narrow defile, when all at once Marcelline and her companion stopped, and, on seeing this, Florae pressed on more vigorously than ever.
