We all know about your operations here." Bishop made no reply, but turned to walk on, when Frank rose to his feet, and exclaimed: "Hold on, here! you are not going through this room with that candle.
Go back instantly where you belong, and don't show your face in here again." Bishop saw that Frank was in earnest, and, without saying a word, he turned and walked into his quarters.
Frank had a twofold object in talking to him as he did.

He wanted to let him know that his fellow-prisoners all knew what he had done, and he wished, also, to deter him from coming into that room again, as he had determined to make another attempt at escape that very night.

The traitor had no sooner disappeared than Frank descended the stairs that led down into the hall, at the foot of which there were two guards posted.
"Hallo, Yank!" said one of them, as Frank came down, "I reckon as how you had better travel right back up sta'rs agin, 'cause it's agin orders to 'low you fellers to come down here a'ter dark." "I know it is," answered Frank; "but it is so awful hot up stairs that I can't stand it.

You'll let me stay down here long enough to cool off a little, won't you ?" "Wal," answered the guard, who really seemed to be a kind-hearted fellow, "I reckon as how you mought stay here a minit; but you mustn't stay no longer." "All right," answered Frank; and he seated himself on the lower step, and talked with the guards until he was informed that it was high time he was "travelin' back up sta'rs." "Very well," answered Frank, rising to his feet, and stretching himself, "I'll go, if you want me to." And he _did_ go.

With one bound he dashed by the astonished guards, and, before they could fire a shot, he had disappeared in the darkness.
His escape had been accomplished much easier than he had anticipated.
He had expected at least a shot from the guards, and, perhaps, a struggle with them; for, when he left his quarters, he had determined to escape, or die in the attempt.
