Our next step was to draw the rope wholly into the dormitory and fasten its wet end to the bass viol.  On the top of this, it will be remembered, there were two S-shaped openings which we had cut to make it serviceable as a sound board.  These Joe had now covered over with the broken skin of the drum, to make the box water tight.  We pushed it through the tunnel, and I let it down into the moat, very slowly, so that it might not strike the wall and draw the sentry’s attention.  When the rope was paid out to its full length I wrapped a coil of bast about my shoulders, and, having suspended from my neck a short plank from the head of the bed, I bade the men in a whisper to remember the further plan we had arranged, and made my way down the rope—­a feat that offered no difficulty to a seaman even so little practiced as I.

Coming safely to our musical raft, I was not long in discovering it to be a very cranky thing, so that I had to keep my hold of the rope in order to maintain my balance.  But in a short time I was able to defeat the raft’s attempts to turn turtle, and then, kneeling on it, still gripping the rope, I looked anxiously for signs that the attention of the sentry on the battlements had been awakened.  But I heard his footsteps approach and recede at the same measured pace; ’twas clear he suspected nothing; and without more delay I began to work the raft towards the far side of the moat, using the short plank I had brought with me as a paddle.  So that no sound of splashing might rise to betray us, at every stroke I dug the paddle into the mud, which, as I had suspected, came to within a little of the surface; indeed, the depth of water was barely sufficient to float the raft, with my weight on it.

A most unsavory odor resulted from the stirring of the mud; but a greater inconvenience was the tendency of the raft to lurch.  Holding on to the rope with one hand, I instinctively pulled upon it to maintain my equilibrium when I felt myself toppling, with the result that the raft moved backward, and I had to begin my punting again.  Fortunately, the width of the moat was little more than thrice the length of my crazy craft, in spite of whose instability I succeeded in reaching the opposite side.

Here, however, I found that my difficulties were by no means over.  The water was low in the moat, and the bank, perfectly free from vegetation, rose almost vertically to a height of six or eight feet.  On a moonlit night I must have been seen if the sentry had glanced in my direction; dark as it was, I feared it was not so dark but that my moving shape might be descried.  I waited:  not hearing the sentry’s footsteps, I began to fear the worst; but finding after a time that no alarm had been given, and that all was still about me, I first fastened the coil of bast I had brought on my shoulders to the end of the rope where it was knotted about the raft, and then began to clamber up the bank, somewhat incommoded by having to keep a hold of the bast with one hand.
