It began in the swimming pool at Glen Ellen. Between swims it was our wont to come out and lie in the sand and let our skins breathe the warm air and soak in the sunshine. Roscoe was a yachtsman. I had followed the sea a bit. It was inevitable that we should talk about boats. We talked about small boats, and the seaworthiness of small boats. We instanced Captain Slocum and his three years’ voyage around the world in the Spray. We asserted that we were not afraid to go around the world in a small boat, say forty feet long. We asserted furthermore that we would like to do it. We asserted finally that there was nothing in this world we’d like better than a chance to do it. “Let us do it,” we said . . . in fun. Then I asked Charmian privily if she’d really care to do it, and she said that it was too good to be true. The next time we breathed our skins in the sand by the swimming pool I said to Roscoe, “Let us do it.” I was in earnest, and so was he, for he said: “When shall we start?”
