the white clouds scudding by overhead. Abby came walking down the beach towards him, tanned a deep brown from head to foot, dressed as the Polynesians had dressed before Captain Cook had discovered them. "You're every bit as beautiful as the women described in the old tales of the South Sea Islands," Nat said as she sat down beside him. "And you're as big a flatterer as any sailor who ever told those stories," she answered, although she was pleased by his admiration.

"But I'm afraid we must," Nat said slowly, "And soon, too. We don't dare stay too long in one place." From the islands, Nat and Abby drifted on from century to century, usually stopping in post-war periods when both governments and populations were preoccupied with constructive social
