A careful search was made of the rooms. They stamped on the floors, rapped on the walls with pistol butts, ripped up the silken covers and the thick mattresses, but found nothing. The men finally stopped their search, and gathered in a group around the massive table. Beany, sitting on the edge of the table, jounced up and down and thought that he had never seen a piece of furniture quite so solid. He took out a penknife and tried to whittle the edge but the keen blade scarcely made an impression on the ironwood seasoned for ages. Porky, watching his brother, listened to the conversation.
“Somewhere down here there is a hiding place for papers or money, or perhaps both,” said one of the officers, a keen-faced, thoughtful man, studying the room as he could see it in the flickering light of the two candles which, now burned down to the merest stubs, afforded a dim, uncertain light.
“We have given it a pretty thorough combing over,” said another officer, frowning.
“I can’t help it,” stubbornly answered the other. “It is in just such places as this where valuable secrets are often hidden.”
“What about the dynamite?” demanded some one else. “It does not seem as though they would hide anything of any value to themselves in a spot that they were willing to blow up.”
“A bomb that size would not have wrecked this room. Did you notice the thickness of the walls?”
The talk went on while Beany whittled and pried away industriously at the table edge. He found a crack in the wood and pried his knife blade into that. The blade entered in a tantalizing manner, slipped smoothly along, then struck metal. Beany pushed. Porky, who was watching, came closer and peered down the crack. Beany pushed harder, pushed as hard as he could, and suddenly felt himself flung off the table as the big top flew up and hurled him aside.
Powerful springs had opened the two heavy slabs of oak that formed the table. Two pieces now stood open like a pair of doors and within lay a long, flat box which completely filled the space. The box was of iron, heavily barred and padlocked. Four soldiers pried it from its place and, escorted by the whole party, it was carried to General Pershing, still working at his desk.
Once more the boys had unearthed a mystery.
