"I'd like to see anybody stop that girl," growled Joe.

"She's as reckless as she can be," said Neale.

"Aw, say!" exclaimed Wib, as they called young Ketchell, "is the roof really unsafe?"

"We don't know," Neale said, in a worried tone. Then suddenly there was a sharp crack from inside the snow castle.

"Crickey! it's coming down!" exclaimed Wilbur.

"What was that, Neale?" demanded Joe Eldred.

"That pillar's gone!" exclaimed Neale O'Neil, pointing to one of the wooden supports by which the roof of planks and snow was partly upheld.

On the tail of his declaration there was another crash and a second support, farther down the hall, was splintered.

"The roof's coming down, Trix! Come back! come back!" shrieked Agnes.

Trix was at the far end. She had turned swiftly and they could see her face. The wooden supports giving way between her and the exit frightened the reckless girl immeasurably.
