You have professed to be Union people," continued Frank, settling himself back in his seat, and coolly crossing his legs, "and have been treated as such; you have, however, attempted to betray us, by communicating such of our plans and movements as you could learn to the rebels.

But you have been discovered at last.

You, gentlemen, will please consider yourselves my prisoners.

Miss Phillips, have the kindness to produce that mail-bag, and the signal-book you took from the captain.

If you refuse, I shall be obliged to take you on board the ship, as a prisoner." The girl saw that there was no alternative, and she pulled from under the sofa, where Frank sat, the mail-bag, which appeared to be well filled with letters, and dispatched a servant to her room after the signal-book, which was to have been sent across the river with the mail.
After Frank had relieved the lieutenant of his weapons, he called two of his men into the house, and, after delivering the prisoners into their charge, returned to the vessel.
That evening the captain examined the mail, and found several letters which showed, beyond a doubt, that their prisoners were connected with the rebel army; and they were, accordingly, sent to the Admiral, on the first steamer that went up the river.
About two weeks afterward, the captain of the Ticonderoga received orders to proceed with his vessel to Helena, and take command of an expedition which was preparing to start down the Yazoo Pass.
