"We might have such ships by then." Paul tried to sound judicial. "Say the Year Eighteen or Nineteen. Yes, a coastal exploration might be better than trying to cross the continent. Not a circumnavigation though, at first."
Dunin's big face blossomed in a grin. "Only about thirty-six thousand miles by the old map made from the air. Open water at north and south poles, plenty of it. Could do it in less than a year."
"More like fifty thousand, allowing for deflections, tacking, pull of currents we don't know. Storms, flat calms, contrary winds, repairs, expeditions ashore for provisions. You pull your horns in just a bit, my girl. Do you remember a desert plateau the map shows in the southern hemisphere? Solid cliff rising out of the sea for over seven hundred miles, and on top of it roasting sand all the way across the continent—and that plateau is only a small part of the coastal desolation down there. From the equator to the 30th parallel I don't think you'd have a chance to go ashore—and nothing to help you if you did."
Dunin still grinned. "Just sail past it."
"Yes—well out to sea, with the equatorial sun at work on you. Very few islands in that region, some of them bare rock." And he thought: If I might go myself...! I am fifty now, in Earth years, a young fifty....
He knew also that Dorothy would not prevent him. She would not go herself: she would remain at Adelphi, faithful to the daily things, undramatic labors and loyalties that make civilization something more than a vision. She was a young thirty-eight, though she had already borne five children. If he went away, she would mind the watch fires on the beaches, as she had done nine years ago; she would work in the school, the house, the gardens, stand by Christopher Wright during the depressions that sometimes overcame him. She would grow old waiting. Therefore, Paul knew, he would never leave her. "The explorations will come in good time, Dunin," he said. "You'll have 150 years to watch and take part. I think you'll live to see the other continent too, and the great islands in the southwest. In the meantime—there's so much exploring to be done right here!" He watched the water too, aware of Dorothy's face turned to him, sober and appraising. "You know, Dunin—that island we visited today—that could hold a community of a thousand between its two little hills. And I'm remembering the one forty miles north of us. Argo II was swept ashore there: get Doc to tell you that story sometime. I was sick for a week and laid up in one of the limestone caves while the others repaired the raft. A round island less than five miles across. We might sail there next trip."
"The other continent," Dunin murmured, and she watched the rising blue-green mound of Adelphi in the south. "The islands of the southwest...."
Dorothy leaned against the hand-hewn rail, looking northeast, saying lightly, "There he is...." The stone figure in the coastal range grew visible as the channel current pressed them a little too far eastward. The vast features were not clear; one could find the line of shoulder. "And Sears said, 'He looks west of the sun.' Was it long ago you told me that, Paul?"
"In a way it was.... Penny for 'em, Dorothy?"
"Oh——" Her brown face crinkled in the way he hoped for. "I was climbing down off philosophy with my usual bump—wondering what hell the twins have been raising while we're away. Brodaa's patience with them passes belief. With her own three sets of twins she's had practice. I wish Pak could have had children. Twenty-nine—late middle age for her people.... Helen's going to make a better med student than ever I was—don't you think, Paul? Seems like more than just a kid's enthusiasm."
