By now they were rattling through the modern town of Heidelberg, the plain walls of which looked bare after the lawless pomp of carving and form on the old castle; they had not even the bizarre, affected grace of the architecture then decking American countrysides. But Margaret thought how homelike and honest the houses looked; staunch and trusty, like the German. Butler, just then, was praising American buggies, from which he made a general transition to the customs of society. "In America, is it not," says he, "the young ladies drive alone with young men?" "Yes, very often. But not with you?" "Oh, no, _mein fraulein_, this is the first time I am alone with a young lady!" She had called herself old for so long that there was a distinct pleasure in being "a young lady" to him, and she had not time to remember it partook of the nature of deceit, because he sent a wave of confusion over her by continuing: "In America, also, one would propose marriage to a lady, herself, before to her father?" "It is our custom," agreed Margaret, "but"--with her prim teacher's air--"your custom is far more decorous." His face fell, then promptly brightened. "Perhaps it would be best to speak to both, so near the same time one can. But this is another thing you must explain me. How is it most preferable to the lady, that one shall write or shall come--" "Oh, write," said Margaret quickly. How silly of her to suddenly feel so frightened; she wished that she were in a room and not in a carriage with him; involuntarily she shrank back into her own corner, and she found that she was playing with the soiled and frayed edges of a tear in the cloth of the side-curtain and watching her pearl-colored fingers. Those gloves she had put on new, that day. How reckless! But she had not the resolution to desist. His voice dragged a little, "Ah, yes, if she would refuse, but if--_not_?" "In any case," said she. "Look!" he exclaimed, "at the sunset. Ah, is it not lovely?" Of a sudden they were looking, not at the sunset, but into each other's eyes; and all about them was that wonderful, transfiguring glow, and it seemed as if there were nothing in the whole world that he had not said. "Is it to the right, Herr Captain?" asked the driver, turning on his seat to divide a benign and semi-intoxicated smile between them. Then it was hardly a moment until the yellow stucco of the pension jumped at their eyes, around a corner; and there were the clergyman's widow and the teacher at the door. They fell upon the carriage in a clamor of explanation and sympathy; they were at her side when he bowed over her hand and kissed it, saying, "_Aufwiedersehen_."
