"For some reasons of his own," answered Ned mischievously.

As the good things were spread before them the eyes of the lads lighted appreciatively, and all helped themselves gratefully.

It was a jolly party, untouched by the air of mystery that was supposed to surround the place.

"Why, where is Master Stacy?" asked Ruth Brayton in surprise, after they had been eating a few moments.

"Chunky? That's so, where is he?" demanded Walter, glancing over the railing into the auditorium below.

No one seemed to know.

"He's prowling around the place somewhere," said Ned. "But what surprises me is that he doesn't scent the food and come running. It's not like him to hang back when there is anything good to eat."

"Call him," suggested Margaret.

"I will. O-h-h Chunky!"

There was no reply.
