She was aroused from these reflections by a distant glimpse, through the trees, of Mr. Robert Worthington. He was standing quite alone on the edge of the park, his hands in his pockets, staring at the White House. Cynthia half rose, and then sat down and looked at him again. He wore a light gray, loose-fitting suit and a straw hat, and she could not but acknowledge that there was something stalwart and clean and altogether appealing in him. She wondered, indeed, why he now failed to appeal to Miss Duncan, and she began to doubt the sincerity of that young lady's statements. Bob certainly was not romantic, but he was a man--or would be very soon. Cynthia sat still, although her impulse was to go away. She scarcely analyzed her feeling of wishing to avoid him. It may not be well, indeed, to analyze them on paper too closely. She had an instinct that only pain could come from frequent meetings, and she knew now what but a week ago was a surmise, that he belonged to the world of which she had been dreaming--Mrs. Duncan's world. Again, there was that mysterious barrier between them of which she had seen so many evidences. And yet she sat still on her bench and looked at him. Presently he turned, slowly, as if her eyes had compelled his. She sat still--it was too late, then. In less than a minute he was standing beside her, looking down at her with a smile that had in it a touch of reproach. "How do you do, Mr. Worthington?" said Cynthia, quietly. "Mr. Worthington!" he cried, "you haven't called me that before. We are not children any more," she said. "What difference does that make?" "A great deal," said Cynthia, not caring to define it. "Cynthia," said Mr. Worthington, sitting down on the beach and facing her, "do you think you've treated me just right?" "Of course I do," she said, "or I should have treated you differently." Bob ignored such quibbling. "Why did you run away from that baseball game in Brampton? And why couldn't you have answered my letter yesterday, if it were only a line? And why have you avoided me here in Washington?" It is very difficult to answer for another questions which one cannot answer for one's self. "I haven't avoided you," said Cynthia. "I've been looking for you all over town this morning," said Bob, with pardonable exaggeration, "and I believe that idiot Somers has, too." "Then why should you call him an idiot?" Cynthia flashed. Bob laughed. "How you do catch a fellow up!" said he; admiringly. "We both found out you'd gone out for a walk alone." "How did you find it out?" "Well," said Bob, hesitating, "we asked the colored doorkeeper." "Mr. Worthington," said Cynthia, with an indignation that made him quail, "do you think it right to ask a doorkeeper to spy on my movements?" "I'm sorry, Cynthia," he gasped, "I--I didn't think of it that way--and he won't tell. Desperate cases require desperate remedies, you know." But Cynthia was not appeased.
