"Rudiments. Of course I couldn't, for example, discourse with authority upon the heteropterous mictidae or tell you in what genus or genera the prothorax and femora are digitate; or whether climatic and polymorphic forms of certain diurnal lepidoptera occur within certain boreal limits. I have only a vague and superficial knowledge of any science, you see." "I see," he said gravely. She leaned forward thoughtfully, her pretty hands loosely interlaced upon her knee. "Now," she said, "tell me about this danger that such a girl as I must guard against." "There is no danger," he said slowly. "But they told me----" "Let them tell you what it is, then." "No; you tell me?" "I can't." "Why?" "Because--I simply can't." "Are you ashamed to?" "Perhaps--" He lifted his boxed sketching-kit by the strap, swung it, then set it carefully upon the ground: "Perhaps it is because I am ashamed to admit that there could be any danger to any woman in this world of men." She looked at him so seriously that he straightened up and began to laugh. But she did not forget anything he had said, and she began her questions at once: "Why should you not walk with me?" "I'll take that back," he said, still laughing; "there is every reason why I should walk with you." "Oh!... But you said----" "All I meant was not for you, but for the ordinary sort of girl. Now, the ordinary, every-day, garden girl does not concern you----" "Yes, she does! Why am I not like her?" "Don't attempt to be----" "_Am_ I different--very different?" "Superbly different!" The flush came to his face with the impulsive words. She considered him in silence, then: "Should I have been offended because you came into the Park to find me? And why did you? Do you find me interesting?" "So interesting," he said, "that I don't know what I shall do when you go away." Another pause; she was deeply absorbed with her own thoughts. He watched her, the color still in his face, and in his eyes a growing fascination. "I'm not out," she said, resting her chin on one gloved hand, "so we're not likely to meet at any of those jolly things you go to. What do you think we'd better do?--because they've all warned me against doing just what you and I have done." "Speaking without knowing each other?" he asked guiltily. "Yes.... But I did it first to you. Still, when I tell them about it, they won't let you come to visit me. I tried it once. I was in a car, and such an attractive man looked at me as though he wanted to speak, and so when I got out of the car he got out, and I thought he seemed rather timid, so I asked him where Tiffany's was. I really didn't know, either. So we had such a jolly walk together up Fifth Avenue, and when I said good-by he was so anxious to see me again, and I told him where I lived. But--do you know?--when I explained about it at home they acted so strangely, and they never would tell me whether or not he ever came." "Then you intend to tell them all about--_us_?"
