"But I tell you that I heard him in here early in the afternoon, and the darkey told me his team was in the stable. Now, how could he have gotten the glycerine or cartridges out of here while six of us have been on duty all the time?"

And from the tone of Newcombe's voice it was easy to understand that he was very angry with these colleagues of his for doubting his ability to watch three boys.

"Are you certain it was Bob whom you heard?" asked the first speaker. "He may have left some one here, and been at Hoxie's before you arrived."

"I am certain there was some one here," said Newcombe, speaking less decidedly than before, "and I would be willing to bet everything I own that it was Bob Hubbard."

"Betting is a very bad way to settle disputes, Mr. Newcombe," said Bob, laughingly, shouting so that every one outside could hear his voice, "and I would advise you to give it up in the future; but in this particular case you would win the money."

"There! What did I tell you?" cried the detective to his visitors; and it is very probable that just at that moment he looked upon Bob as a true friend.

"Yes, Bob is there," said the man, reluctantly; "but Jim and Dick were at the well."

"Here's Dick!" shouted that young gentleman; "and when you two want to hold an animated conversation about either one of us, try not to start it at night, nor so near the door of a sleeping-room as to disturb those who may need a little rest."

"And here is Jim!" shouted that young moonlighter. "So now that you know we are here, where Brother Newcombe has been watching for the last dozen hours, suppose the whole posse of you drive back to Bradford, where you belong."

For a moment there was a profound silence outside, as if this last astute detective was too much surprised to be able to speak, and then Mr. Newcombe burst into an uncontrollable fit of triumphant laughter. He knew that it was impossible for any number of boys to fool him, and very likely he almost pitied his brother-detective for being so simple.
