"Why, I forgot all about it," she said. "I was meaner than you anyhow." And she kissed her.

Amy put her arms around Margery before she could speak. "It's all right, Margery; forgive me, too," she whispered.

And so, at peace with all the world and each other, the Happy Thought Club, that had so narrowly escaped destruction, sallied forth to eat ice-cream.


[CHAPTER IV.]

THE MYSTERIOUS TENANT.

The opening of the post-office was a great success. Amy, who was the first to go into office as postmistress, had a busy time for the three days of her term. Every member of the H. T. C. wrote the other four one letter a day with praiseworthy regularity, so there were twenty letters daily for the postmistress of Blissylvania to handle, not to mention packages and papers, and the invisible city of Blissylvania did more mail business than many of Uncle Sam's offices in far-off country places. There was a slight falling off in mail on the second day of Trix's term, which followed Amy's, for Jack found so much and such regular correspondence exhausting to mind and body, and was first to complain that he had nothing to say. It was even found, when the ladies compared notes on the fifth day after the office opened, that he had basely written one letter, and copied it three times—Miss Isabel requiring a different style of composition—but they had agreed to feign ignorance of this action, charitably excusing it on the ground of boys' well-known deficiencies.

There was difficulty about Margery's address. She insisted that the whole title and address must be used, but Jack declared it was expecting too much of any one to write on the small space of the back of their letters, which for economy's sake were so folded as to serve instead of envelopes: "Lady Griselda, At the Castle of the Lonely Lake, Blissylvania, New York," which was what Margery desired.

They compromised, following Miss Isabel's suggestion, on "Lady Griselda of the Castle, Blissylvania, New York," because, as Miss Isabel pointed out, there could be no mistake, there being but one Lady Griselda and one castle.
