But at last I caught it, and slipping back into the room, pull’d it after me, yard upon yard. My heart went loud and fast. There was nothing to fasten it to but an iron staple in the door, that meant losing the width of my cell, some six feet. This, however, must be risk’d, and I made the end fast, lower’d the other out of window again, and climbing to a sitting posture on the window sill, thrust out my legs over the gulf. Thankful was I that darkness had fallen before this, and hidden the giddy depths below me. I gripp’d the rope and push’d myself inch by inch through the window, and out over the ledge. For a moment I dangled, without courage to move a hand. Then, wreathing my legs round the rope, I loosed my left hand, and caught with it again some six inches lower. And so, down I went. Minute follow’d minute, and left me still descending, six inches at a time, and looking neither above nor below, but always at the grey wall that seem’d sliding up in front of me. The first dizziness was over, but a horrible aching of the arms had taken the place of it. ’Twas growing intolerable, when suddenly my legs, that sought to close round the rope, found space only. I had come to the end. I look’d down. A yard below my feet the beam of the gallows gleam’d palely out of the darkness. Here was my chance. I let my hands slip down the last foot or so of rope, hung for a moment, then dropp’d for the beam. My feet miss’d it, as I intended they should; but I flung both arms out and caught it, bringing myself up with a jerk. While yet I hung clawing, I heard a footstep coming through the gateway between the two wards. Here was a fix. With all speed and silence I drew myself up to the beam, found a hold with one knee upon it, got astride, and lay down at length, flattening my body down against the timber. Yet all the while I felt sure I must have been heard. The footsteps drew nearer, and pass’d almost under the gallows. ’Twas an officer, for, as he pass’d, he called out— “Sergeant Downs! Sergeant Downs!” A voice from the guardroom in the barbican answer’d him through the darkness. “Why is not the watch set?” “In a minute, sir: it wants a minute to six.” “I thought the Colonel order’d it at half past five?” In the silence that follow’d, the barbican clock began to strike, and half a dozen troopers tumbled out from the guardroom, some laughing, some grumbling at the coldness of the night. The officer return’d to the inner ward as they dispersed to their posts: and soon there was silence again, save for the _tramp-tramp_ of a sentry crossing and recrossing the pavement below me.
