Armand, and the devoted friends who were helping him in his difficult enterprise, were all from the first of the opinion that there was no hope of rescuing or carrying off Sister Theresa by force or stratagem from the side of the little town. Wherefore these bold spirits, with one accord, determined to take the bull by the horns. They would make a way to the convent at the most seemingly inaccessible point; like General Lamarque, at the storming of Capri, they would conquer Nature. The cliff at the end of the island, a sheer block of granite, afforded even less hold than the rock of Capri. So it seemed at least to Montriveau, who had taken part in that incredible exploit, while the nuns in his eyes were much more redoubtable than Sir Hudson Lowe. To raise a hubbub over carrying off the Duchess would cover them with confusion. They might as well set siege to the town and convent, like pirates, and leave not a single soul to tell of their victory. So for them their expedition wore but two aspects. There should be a conflagration and a feat of arms that should dismay all Europe, while the motives of the crime remained unknown; or, on the other hand, a mysterious, aerial descent which should persuade the nuns that the Devil himself had paid them a visit. They had decided upon the latter course in the secret council held before they left Paris, and subsequently everything had been done to insure the success of an expedition which promised some real excitement to jaded spirits weary of Paris and its pleasures. An extremely light pirogue, made at Marseilles on a Malayan model, enabled them to cross the reef, until the rocks rose from out of the water. Then two cables of iron wire were fastened several feet apart between one rock and another. These wire ropes slanted upwards and downwards in opposite directions, so that baskets of iron wire could travel to and fro along them; and in this manner the rocks were covered with a system of baskets and wire-cables, not unlike the filaments which a certain species of spider weaves about a tree. The Chinese, an essentially imitative people, were the first to take a lesson from the work of instinct. Fragile as these bridges were, they were always ready for use; high waves and the caprices of the sea could not throw them out of working order; the ropes hung just sufficiently slack, so as to present to the breakers that particular curve discovered by Cachin, the immortal creator of the harbour at Cherbourg. Against this cunningly devised line the angry surge is powerless; the law of that curve was a secret wrested from Nature by that faculty of observation in which nearly all human genius consists.
