boat seemed to be perfectly still. We could see water rushing past us. Far off, in Mike's Casino, the band was playing "Did Your Mother Come From Ireland?" I stopped being sad and got sentimental. That song always makes me sentimental. "It isn't dangerous," Fatty admitted. "But I just remembered that the Portuguese Man-Of-War has batteries of stingers that it uses to catch fish. They can hurt a man sometimes, too. And in anything this big—Of course, we're inside a boat and it can't get at us." "You hope. Something tells me that I won't be home at eleven tonight. And if that's just supposed to be an air-filled bladder, what are those black things floating in it? Eyes?" "They sure look like eyes. Feel like eyes."

Beyond the water, there was a kind of gray haze that was transparent enough for me to see the lights of Mike's Casino where they were still playing "Did Your Mother Come From Ireland?" This gray haze went all the way around, covering the mast and the gaff tops. When we
