"It is Mr. Halliburn!" was the whispered exclamation of Win.

"Hush! Don't speak, sir," said Deck, as he proceeded to remove the straps which bound him, aided by the guide.

"Not a sound, sir!" continued the young officer. "You are safe, and so is Miss Morgan, and also the treasure-chest. Not a word!"

Win assisted him to sit up on the sofa, and then went into the other front room with Deck. The latter warned her as he had the man not to speak, and then asked the guide who she was, while both of them began at once to remove her bonds.

"Mrs. Halliburn," replied Win, who assisted her to rise as soon as she was liberated.

"Now, Win, if you wish to go and find your horse, I can spare you, though I should like very well to have you remain longer."

"I want to see this thing through," answered Milton. "I have seen you pile up all the incidents of this affair, like those in a novel; and now I want to see you pull out the pin in the last chapter, and let everything down in a heap. I suppose Grace is safe with your men to guard her."

"I will vouch for her safety. I am going to pull out the pin now," added Deck, as he beckoned the bugler to follow him to the front or east piazza.

He ordered him to sound the "Advance," and the command was promptly obeyed. The ringing notes of the startling call sounded clearly in the silence of the retired locality, and it could have been heard at least half a mile. Life Knox's force came first, and Deck directed the sergeant to surround the house, and shoot down any guerilla that attempted to escape. The bugle sounded the second call, and Corporal Tilford and his dozen men appeared in front of the mansion. The sergeant continued to station the men till all of them were in position.

The marauders flocked to the windows, and found half a dozen carbines pointed at each opening. It checked their enthusiasm at once. At the staircase those who proposed to descend found as many pieces aimed at them. It looked just then as though Lieutenant Lyon had bagged the twenty-two guerillas in the upper story of the mansion.
