On the board was a large poster, the ink on which was scarcely dry. At the top, in enormous black letters, they read:

$1000 REWARD

Underneath, in slightly smaller type, came the following:

The above reward will be paid for information leading to the arrest of the person or persons who broke into Tower Mansion and stole from a safe in the library jewels and securities, as follows—

Then came a list of the jewels and negotiable bonds that had been taken from Tower Mansion, the jewels being fully described and the numbers of the bonds being given. It was announced that the reward was offered by Hurd Applegate.

"Why, that must mean that the charge against Mr. Robinson has been dropped!" exclaimed Joe.

"It looks like it. Let's go and see if we can't find Slim."

All about them people were commenting on the size of the reward, and there were many expressions of envy for the person who should be fortunate enough to solve the mystery.

"A thousand dollars!" said Frank, as they made their way out of the post office. "That's a lot of money, Joe."

"I'll say it is."
