very red. She
looked angry, and stamped her foot. Then she burst into a giggle, and
slid the paper back out of sight again.

She came back to her friend with a mixture of emotions expressed on her
countenance. "What do you suppose?" she demanded.

"Suppose about what?" asked Wyn.

"What do you suppose Dave wrote on that paper?"

"I give it up. Something that didn't concern us, as I told you."

"You're wrong," cried Frank, divided between wrath and amusement. "And
it's just the very _meanest_ thing!"

"Why, you excite my curiosity," admitted Wyn.

"That's what he did it for," declared Frankie.

"_What_ did he write?" cried Wyn. "Out with it."

"He wrote: 'I bet an ice-cream treat all around that your curiosity will
not permit you to leave this alone.' Now! could anything be meaner?"

"Ha, ha!" chuckled Wyn.

"Don't you see? We can't claim the treat without giving ourselves away?

straightaway dash, while Frank was second and Grace Hedges third in the
same race. The people who had come up from Denton cheered the girls
enthusiastically. When the parents who had been so afraid for their
daughters' safety saw how well able the girls were to take care of
themselves, their anxiety was allayed.

After these swimming contests there was an interval of two hours for
refreshments. A caterer had prepared tables of sandwiches and cold
drinks, as well as ice cream and cake, on one of the bigger docks
belonging to Braisely Park. In fact, it was Dr. Shelton's dock.

The catboat races were to follow the intermission and Wyn found that the
Jarley _Coquette_ had been entered. She ran over to the dock from
which the "cats" were to start for the line, and as she approached the
spot she heard loud voices and saw a lit
