We had one advantage that I have not mentioned, and it was this. We were of course locked in, but there was a bolt on the door, so that we could secure ourselves on the inside from any sudden interruption; and by keeping the door fastened, there would be time to hide the saw and brush away the dust before any one who came was admitted.
My position was facing the little round window of the cabin as Mr Frewen made the first start toward obtaining our freedom; and as the saw began to bite at the wood with a sound like that which would be made by a gnawing mouse, I stood gazing out at the beauty of the grand tropic night. It was very dark, but it was a transparent darkness, with the sky within reach of my vision thickly spangled with stars, which were so brightly reflected in the calm sea through which we were gliding gently, that there were moments when I could hardly tell where the sky ended and the sea began.
Then faintly and steadily rasp, rasp, rasp went the saw, with so little noise that it did not seem likely that any one out in the saloon would hear it; and though at the first cut or two my heart began to beat with dread, a few minutes later it was throbbing with exultation.
For every gnaw of that little keen-toothed instrument sent a thrill of hope through me; and I did not stop to consider what we were to do, or what were our probabilities of success when we reached the saloon, for it seemed to me then that the rest would come. And on it went, gnaw, gnaw, gnaw at the soft grain of the pine-wood board, very slowly, but very surely, I knew; and I was just going to whisper to Mr Frewen, and ask him whether he would like me to take a turn, when the sawing stopped.
“Only for a few minutes’ breath,” he whispered.
“Shall I take a turn?”
“When we cut the bottom one. I am taller and stronger, and can get at this better than you.”
Then he began again, and I gazed through the cabin-window, and listened both to his working on the thick board, and for any sound which might indicate that a sentry had taken alarm.
But all was silent; and comforting myself with the belief that if the noise was heard it might be taken for the gnawing of a rat, I listened and watched the stars.
At last I was in such a state of nervous excitement that I was on the point of begging my companion, to let me take a turn, when from being so intensely hot I suddenly turned speechless and cold. For it suddenly occurred to me that the stars were blotted out, and that the night was blacker.
