"I sat next the most romantic-looking boy I ever saw. No, my dear, no occasion for excitement; he must be years younger than I am; but the most beautiful person you ever saw—hollow-cheeked, broad-browed like that picture you adore so of Father Damien, oh perhaps I'm thinking of an illustration of Rossetti; and he can talk, too, I promise you. He's an experimental chemist in some great manufacturing company, which at this age—"

In the next letter it appeared that he wasn't really years younger—hardly a year; in fact, nothing to speak of. Letitia began to write a good deal about the scientific point of view—its stimulating quality—its powers of observation—its justice—"almost as just as you are, Nan."

Nan waited for each letter as if it were the next installment of a serial. She had seen Letitia through a good many such affairs, and she knew that before long her friend would stage a quarrel. It was a good way, Letty said, of finding out how much he cared; although, as a matter of fact, Nan noticed that she never precipitated it until she was sure the unfortunate man in question cared enough to be at a disadvantage.

But in Roger's case, when she had said sadly, "I'm afraid, Mr. Rossiter, that this means our friendship is ended," he had answered without a word of pleading, "Yes, I'm quite sure it does."

Letitia, a little startled, had asked, "What? You wish it too?"

"No," he had said; "but the fact that you do ends it automatically."

She had some difficulty in extricating herself from her own ultimatum. Naturally, her respect for him increased.

"I'm almost glad you are not here, Nan," she wrote. "He is so honest he could not help loving your honesty. I feel as if together, somehow, you would both find me out."

She inclosed a little photograph of him to show Nan what a splendid-looking person he was; but it was not his beauty she dwelt upon, but his straight, keen eyes and the fine firmness of his mouth—not the determination of the self-conscious bulldog, which so many people assume in a photograph, but just a nice steely fixity of purpose. Yes, Nan, far away in China, with plenty of leisure for reflection, found that for the first time she envied her friend.
