"It's getting so noisy in there, I'm 'fraid they won't even hear wild Indians," ventured Jimmie Brown at the top of his voice.

"Hush," cautioned Billy, "don't talk too loud. Music-boxes and wind and waves and talking girls sometimes keep still at the same time."

"Oh, look," exclaimed the twins, "what's coming?"

"Frenchy and Bud and Buzz and Tony and their little 'dopted sister Samone," Billy declared, as he began motioning for the new-comers to creep quietly to the fort.

'Phonse took the hint, and soon he and his wondering followers were peering through the evergreen walls.

"What's going to happen?" demanded 'Phonse, with a grin.

"Well," explained Billy, "it's a game, only the girls don't know they're in it. That's a fort, and we're Indians. I'm Minnavavana, the chief, and the rest of you are my braves. You want to play, of course. Samone don't count, though, she's only a papoose."

"But where are your tomahawks, and what's going to happen, I say?" persisted 'Phonse, as he and his brothers crowded around Billy.

"Look," said Jimmie Brown, showing the LeBrinn children a firecracker. "These Indians have guns. Can't you give him a gun, Billy? My pocket's full of matches."
