On Friday Mr. Karner appeared, with a man and his wife, whose name Yetta never troubled herself to remember, and they all went off for a week-end cruise. Most of the time the older people played bridge. Yetta made friends with the sea and a gray-haired old sailor from the Azores, who could speak nothing but Portuguese. Once while at anchor he helped her catch a fish. She would have enjoyed the cruise more if they had let her eat in the forecastle with the crew. She liked Mrs. Karner very much when they were alone together, but it was unpleasant to see her with these others. In time the color returned to Yetta's cheeks, and hearing that Mabel had torn up her resignation, she went back to Washington Square and to work. Except for such crises, Yetta followed rigorously the course of reading which Walter had mapped out for her. The afternoons and evenings belonged to the work of the League, to the very busy life of the real world. The mornings belonged to Walter. Her first thought was always of him. While the coffee was heating, she attended to his mail. After breakfast, with his prospectus spread out before her, she settled herself in one of his chairs and took up one of his books. Following his suggestion she made copious notes, and, when a book was finished, she wrote a thousand words or so on the main ideas she had gained from it. She carefully saved all these notes. When he returned he would see how thoroughly she had followed his directions. On the other side of the world from Yetta, Longman was leading a rough, exciting tent-life among dangerously fanatic natives. It would have been hard to imagine two more sharply contrasting environments. He never dreamed of the loving devotion which was being offered him, so many thousand miles away. He did not suspect how his occasional letters, in reply to her weekly ones, fanned this flame. He was wholly occupied in racing against time and difficulties to complete his work. The expedition was not having an easy time of it. The ruins about which they were digging were regarded by the natives with superstitious veneration. The little group of scientists had only a score of unreliable soldiers for defence, so the real men--Le Marquis d'Hauteville, _Chef de l'expédition_, a wiry, gray-haired veteran of the Algerian Wars; Delanoue, a dandified-looking Parisian, who had carved his name as an explorer in all sorts of outlandish places; Vibert, the photographer, and Walter--had their hands full. They were the rampart, behind which the half-dozen querulous, rather old-maidish specialists measured skulls, gathered fragments of pottery, took rubbings of inscriptions, and collected folk-lore.
