“Don’t tell what we suspect about the dynamiters,” whispered Eddie.

“Of course not!” answered Dee. Presently he turned to the boys. “He says for the whole Wireless Club to pile into Frank’s car tomorrow and come out to Knox for the day.”

“Good work,” said Bill. “I will see if I can get hold of Fat and Skinny. I will telephone so I can talk to Mrs. Bascom if Fatty is out.”

Together they trailed down to the telephone and found that Fatty was just finishing supper. Skinny was there, and both boys were delighted to go.

“What about lunch?” asked Fatty. “Hadn’t we better take along something to eat?”

“Yes, we will have to, because there is no hotel there. Better each one take his own lunch,” suggested Bill.

“That’s a good idea,” said Fatty in a relieved voice. “Then nobody needs to bother about anybody else. What time do we start?”

“Early,” said Bill. “You will have to stir yourself, and we will meet you on the corner of Burnett at six. Don’t be late.”

“All right, I’ll be there, and so will Skinny; and we will each bring our lunch.”

Each boy had a bulging pocket, where his lunch reposed. But Fatty’s pockets did not bulge more than Fatty’s own self made them. Fatty was standing on the corner waiting for them. His back was nearly covered by a large, roomy knapsack that bulged.
