"Then pardon me, madame, because you force me to it. I am going to dance with you an infernal waltz, a riotous polka." "A polka with me! You dare!" "Come, madame, since you insist upon it we must. Keep time to the air. Tra, la, la, la." And joining the act to the words, the merry sailor passed the arm that was free around the bony waist of Sister Prudence, and carried her with him, singing his refrain and whirling her around with such rapidity that, at the end of a few seconds, bewildered, dizzy, and suffocated, she could only gasp the syllables: "Ah, help--help--you--wretch! He--takes--my--breath! Help--help!" And soon overcome by the rapid whirling, Sister Prudence felt her strength failing. The captain saw her about to faint on his arms, and only had time to lay her gently on the grass. "Ho!" at this moment cried Sans-Plume on the other side of the wall, as he threw over the knotted rope to the captain. "The devil, it is high time!" said the captain, rushing after the rope, for the lights and the persons who carried them were no more than fifty steps distant. Armed with pitchforks and guns, they approached the mother superior, who had recovered sufficiently to point over the wall as she said: "There he is getting away!" One of the men, armed with a gun, guided by her gesture, saw the captain, who, thanks to his agility as a sailor, had just gained the crest of the wall. The man fired his gun, but missed his aim. "You! You!" cried he to another man armed like himself. "There he is on the top of the wall reaching for the branches of that tree,--fire!" The second shot was fired just at the moment when Captain Horace, astride one of the branches projecting over the garden, was approaching the trunk of the tree, by means of which he meant to descend on the outside. Scarcely had the second shot been fired, when Horace made a sudden leap, stopped a moment, and then disappeared in the thick foliage of the trees. "Run! run outside!" cried Sister Prudence, still panting for breath. "There is still time to catch them!" The orders of the mother superior were executed, but when they arrived on the boulevard outside, Dolores, the captain, and Sans-Plume had disappeared. They found nothing but the hammock, which was lying a few steps from the spy, who, enveloped in his bag, dolefully uttering smothered groans at the bottom of the ditch. CHAPTER IV. Eight days after the abduction of Dolores Salcedo by Captain Horace, Abbé Ledoux, in bed, received the visit of his physician.
