The walls of these dungeons are as thick as some bed-chambers at home are wide--fifteen feet. We saw the damp, dismal cells in which two of Dumas' heroes passed their confinement--heroes of "Monte Cristo." It was here that the brave Abbe wrote a book with his own blood, with a pen made of a piece of iron hoop, and by the light of a lamp made out of shreds of cloth soaked in grease obtained from his food; and then dug through the thick wall with some trifling instrument which he wrought himself out of a stray piece of iron or table cutlery and freed Dantes from his chains. It was a pity that so many weeks of dreary labor should have come to naught at last. They showed us the noisome cell where the celebrated "Iron Mask"--that ill-starred brother of a hardhearted king of France--was confined for a season before he was sent to hide the strange mystery of his life from the curious in the dungeons of Ste. Marguerite. The place had a far greater interest for us than it could have had if we had known beyond all question who the Iron Mask was, and what his history had been, and why this most unusual punishment had been meted out to him. Mystery! That was the charm. That speechless tongue, those prisoned features, that heart so freighted with unspoken troubles, and that breast so oppressed with its piteous secret had been here. These dank walls had known the man whose dolorous story is a sealed book forever! There was fascination in the spot. CHAPTER XII. We have come five hundred miles by rail through the heart of France. What a bewitching land it is! What a garden! Surely the leagues of bright green lawns are swept and brushed and watered every day and their grasses trimmed by the barber. Surely the hedges are shaped and measured and their symmetry preserved by the most architectural of gardeners. Surely the long straight rows of stately poplars that divide the beautiful landscape like the squares of a checker-board are set with line and plummet, and their uniform height determined with a spirit level. Surely the straight, smooth, pure white turnpikes are jack-planed and sandpapered every day. How else are these marvels of symmetry, cleanliness, and order attained? It is wonderful. There are no unsightly stone walls and never a fence of any kind. There is no dirt, no decay, no rubbish anywhere--nothing that even hints at untidiness --nothing that ever suggests neglect. All is orderly and beautiful--every thing is charming to the eye. We had such glimpses of the Rhone gliding along between its grassy banks; of cosy cottages buried in flowers and shrubbery; of quaint old red-tiled villages with mossy medieval cathedrals looming out of their midst; of wooded hills with ivy-grown towers and turrets of feudal castles projecting above the foliage; such glimpses of Paradise, it seemed to us, such visions of fabled fairyland!
