"[in the tunnel] There's no earthly way of knowing which direction we are going. There's no knowing where we're rowing, or which way the river's flowing. Is it raining? Is it snowing? Is a hurricane a-blowing? BLAH! Not a speck of light is showing, so the danger must be growing. Are the fires of hell a-glowing? Is the grisly reaper mowing?! YES! The danger must be growing, for the rowers keep on rowing... And they're certainly not showing... ANY SIGNS THAT THEY ARE SLOWING!!!"
