Then comes the narrative of two Frenchmen who with incredible effort journeyed one hundred and fifty leagues, being on the road eighteen nights "without eating anything considerable," and were at last so near their liberty as to see a town belonging to the king of Portugal, making them forget their fatigues, when they were unhappily retaken, hurried back to their master, loaded with irons, and condemned to double labor. As they were studying a second escape, they were relieved by death, that constant friend of the slave. This narrative is followed by that of two other Frenchmen, who commenced their escape on the 2d of October, 1693, "having no other guide than the North Star to direct their course." And here ensues that succession of trials which is the lot of the fugitive slave, all of which is told at length. There was peril in leaving the city and passing the outer guards; but when this was done, then came the desert, with its rocks and precipices, where they met "some tigers and many lions," making it hideous with their roaring; but worse than tiger or lion was the fiery thirst that pursued them; and worse than all was man, for it was from him that they feared most. They, too, found themselves in sight of the liberty they had sought with such pain, when, like their predecessors, they were retaken and hurried back. Asked why they had fled, they answered, "For the sake of liberty, and we are guilty of no other crime." Burdened with heavy chains, they were again put to work, with the threat of being burned alive, if they attempted the like again. But notwithstanding all this terrible experience and the menace of death by the flames, they made another attempt, "preferring," says the Catholic father, "all perils and hardships before the insupportable burden of their captivity." Again they failed, and were carried back to fearful torment, when at last they were ransomed by the mission in the name of the French monarch.[86] [86] Busnot, History of the Reign of Muley Ismael, p. 184.
