"Hanged if I know who to write to," he mused. "I never had the habit. I suppose it's done regularly—in society."

"I haven't had a letter in a week," he said. "You see, what I get mostly is bills. Aunt Caroline attends to those. But here's a letter I got last week; we could begin on that, I suppose."

"No, indeed; never bothered about it."

Mary looked disturbed; her sense of order was really offended.

"I think that was very wrong," she observed.
