So they motored to Santa Monica and spent the afternoon on the sands, watching the bathers and admiring the graceful outlines of the big yacht lying at anchor a half mile from the shore. The boat was something of a mystery to everybody. It was named the "Arabella" and had come from Hawaii via San Francisco; but what it was doing here and who the owner might be were questions no one seemed able to answer. Rumor had it that a Japanese prince had come in it to inspect the coast line, but newspaper reporters were forbidden to scale the side and no satisfaction was given their eager questioning by the bluff old captain who commanded the craft.
