Gerard seized the oak chest, and with almost superhuman energy dragged it to the window: a moment ago he could not have moved it. Standing on the chest and looking down, he saw figures at the tower foot. They were so indistinct, they looked like one huge form. He waved his bonnet to them with trembling hand: then he undid the silk rapidly but carefully, and made one end fast to his knife and lowered it till it ceased to draw. Then he counted a hundred. Then pulled the silk carefully up: it came up a little heavier. At last he came to a large knot, and by that knot a stout whipcord was attached to the silk. What could this mean? While he was puzzling himself Margaret's voice came up to him, low but clear. “Draw up, Gerard, till you see liberty.” At the word Gerard drew the whipcord line up, and drew and drew till he came to another knot, and found a cord of some thickness take the place of the whipcord. He had no sooner begun to draw this up, than he found that he had now a heavy weight to deal with. Then the truth suddenly flashed on him, and he went to work and pulled and pulled till the perspiration rolled down him: the weight got heavier and heavier, and at last he was well-nigh exhausted: looking down, he saw in the moonlight a sight that revived him: it was as it were a great snake coming up to him out of the deep shadow cast by the tower. He gave a shout of joy, and a score more wild pulls, and lo! a stout new rope touched his hand: he hauled and hauled, and dragged the end into his prison, and instantly passed it through both handles of the chest in succession, and knotted it firmly; then sat for a moment to recover his breath and collect his courage. The first thing was to make sure that the chest was sound, and capable of resisting his weight poised in mid-air. He jumped with all his force upon it. At the third jump the whole side burst open, and out scuttled the contents, a host of parchments. After the first start and misgiving this gave him, Gerard comprehended that the chest had not burst, but opened: he had doubtless jumped upon some secret spring. Still it shook in some degree his confidence in the chest's powers of resistance; so he gave it an ally: he took the iron bar and fastened it with the small rope across the large rope, and across the window. He now mounted the chest, and from the chest put his foot through the window, and sat half in and half out, with one hand on that part of the rope which was inside. In the silent night he heard his own heart beat.
