Today at last I have spotted a way out. There is a medium sized crack down the side of the rock, and it could be made large enough to be an exit from this awful underwater prison with a mere jackknife! Unfortunately, I was deprived of all weapons upon arrival, but young Mickey still has a small dagger in his pocket. I begin to cut. Hopefully in a few days I will be able to get us both out of this dreadful pinch.
