I’ve been robbed of sense. I’ve been made without resource. I have become inflexible in a flux. When I was on the Good Ship Lollipop, I was held there by wind and sea. When I was on the raft, there was nobody there but me. On this rock I’m fast. Held. I can’t do more than hold on. And wait. Or plunge like a diver to the ocean floor where it is as dark as a fish’s gut and there’s nowhere to go but up. But do I have an alternative, yes. I can beg a lift can’t I? cling on to the coattails of a bird or a fish. If dogs are the friends of man, what are a sailor’s friends? Porpoises. They love us. Like to like they say, though when has a porpoise killed a man, and we have killed so many and for curiosity, not even for food’s or killing’s sake. A porpoise will take me to my love.
