he piece of
paper into Bob's hand.

"All right," he said. "Here's Markham and Boggs' place. You said you were
in this store yesterday, Betty."

"So I was. Come on, Bobby," cried the other girl, hopping out of the car.
"I suppose we shall have to go to the manager or the superintendent or
somebody. Dear me! if we don't find my locket I don't know what I shall
do."

When Betty and Bobby came out of the store, much disappointed, they found
Bob grinning--as Bobby declared--"like a Cheshire cat."

"But never mind the cat," continued Bobby. "What is the matter with that
boy? For boys will laugh at the most serious things. And this is serious,
my poor, dear Betty."

"Indeed it is," agreed her friend, and so they crossed the walk to the
grinning Bob Henderson who had the scrap of newspaper Betty had given him
in his hand.

"Say," he drawled, "who did you say this aunt of Ida Bellethorne is?"

"Mrs. Staples says she is a concert singer--a prima donna," replied Betty.

"She's a prima donna all right," chuckled Bob. "Where now? Oh! To Stone's

"This string of items you handed me is torn out of the sporting page. All
the paragraphs refer to racing matters. That particular one deals with Mr.
Bolter's black mare, Ida Bellethorne. Cliffdale is the place he was
shipping her to far her health."

"Never!" cried Bobby.

"Oh, Bob! Is that so?" gasped Betty.

Bob burst into open laughter. "That's a good one on you and on your
friend, Ida," he declared. "If she has gone to meet her aunt up in New
York State she'll meet a horse instead. How's that for a joke?"

Betty Gordon shook her head without smiling. "I don't see the joke at
all," she said. "Poor Ida! She will be sadly disappointed. And she has
lost her position here with Mrs. Staples. We could see that Mrs. Staples
was angry because she went away."

"Why," cried Bobby, likewise sympathetic, "I think it is horrid--actually
horrid! You needn't laugh, Bob Henderson."

"Shucks!" returned the boy. "I can
