Then they heard the welcome thud of horses’ hoofs and the clink of harness and buckles as Ted appeared.

“Oh, Ted! here’s a letter we want you to post, please,” cried Mollie, “and here’s a penny for the stamp; and, Ted, don’t tell anyone at home about this, please—because—because it’s a secret, and if a reply comes, Ted——”

“Hello! what’s the game?” asked Ted, suspiciously.

“No ‘game’ at all,” said Eileen, indignantly. “It’s a business letter.”

“It’s not a boy you’re writing to on the sly, is it?” asked Ted, with a wink.

“No, we don’t write to boys,” snapped Eileen. “It’s a very important letter, Ted, and there’s nothing wrong about it. It’s—it’s for a good cause.”

“Oh! a charity affair?” said Ted. “Righto, give’s it here. I’ll post him for you all right.”

“Oh! and, Ted, a reply might come, addressed to the Misses Hudson——”

“Mrs. Hudson—your Mother?”

“No, to the Miss Hudsons—us—you know. I suppose it will be M-i-s-s-e-s, so we want you to keep it back, and give it into my hands,” said Mollie.
