She had taken out her handkerchief and now composed herself with difficulty while Jerry's ruffled dignity in silence preened at its feathers. She watched him furtively, I'm sure, between dabs with her handkerchief and at last stopped laughing, got up and offered him her hand. "I've made you angry," she said. "I'm sorry." He found that he had taken her hand and was looking at it. The words he used in describing it were these: "It was small, soft and warm, Roger, and seemed alive with vitality, but it was timid, too, like a young thrush just fallen from its nest." So far as I could discover, he didn't seem to know what to do with her hand, and before he decided anything she had withdrawn it abruptly and was turning away. "I'm going now," she said calmly. "But I've enjoyed being here, awfully. It was very nice of you not to--to throw me over the wall." "I wouldn't have, really," he protested. "But you might have had me arrested, which would have been worse." She opened her tin box. "It's your butterfly, of course. You can have it, if you like." "Oh, I wouldn't take it for anything. Besides, that's no good." "No good?" "No, common. I've got loads of 'em." Her nose wrinkled and then she smiled. "Oh, well, I'll keep it as a souvenir of our acquaintance. Good-by, Jerry." She smiled. "Good-by, Una. I'm sorry--" he paused. "For what?" "If I was cross--" "But you weren't. I shouldn't have laughed." "I think I like you better when you laugh than when--when you're 'bottled up'." "But I mustn't laugh at _you_. I didn't mean to. I just--couldn't help. You've forgiven me, haven't you?" "Of course." She had taken up her hat and now walked away upstream. Jerry followed. "Will you really come next year?" he asked. "I--I should like to show you my specimens." "Next year! Next year is a long way off. You know, I don't belong here. I'm only visiting." "Oh!" She clambered down into the bed of the stream toward the iron railing. Two of the bars, as he could now see, were bent inward at the bottom. When she reached the railing she turned and flashed a smile up at him. "You'd better tell Roger about the broken fence." "Why?" She thrust her net and tin box through the bars and then slipped quickly through the opening. "Why?" he repeated. She stood upright and laughed. "I might come in again." Jerry, I think, must have stood looking down at her wistfully. I cannot believe that the psychology of sex made any matter here. Youth merely responded wordlessly to youth. Had she been a boy it would have been the same. But the girl was clever. "I think I will," she said gayly. "It looks very pretty from out here." "I--I can't invite you," said Jerry. "I should like to, but I--I can't." "I could come without being invited," she laughed. "But you wouldn't, would you?" "I might. I didn't hurt you, did I?" "No," he laughed. "Then I don't see what harm it would do. I'm coming." No reply. "I'm coming tomorrow."
