"This much at least I beg you to tell us, if you hold it square with duty. Was it from within or from without that we were struck? We may desire to try again, and it is well to know friend from foe."

Captain Cottrell laughed at the bold question. He reflected a moment, then made reply.

"You've preached me a sermon on honour, and I'll pay for it with a word of advice. A man's worst foes shall be they of his own household. There's a seed to sow in your heart, Mr. Stark! But since you will have it, then take it. At least I trust that it may serve to break up a little family party of Seven which I hear about. It will be better for all concerned that you respect the prison regulations henceforth. Now, gentlemen, I wish you a very good day."

In darkness and indignation they departed before this cynical speech. Stark and Burnham were for disbelieving it utterly; Commodore Miller, more cautious and more experienced, deemed the assertion not one to ignore without serious reflections.

"'Tis a patent lie," declared Stark. "I marvel that you cannot see it, sir. He actually dared to declare his object in uttering it. He wishes to separate the Seven and scatter them finally. What more certain way of so doing than by making each distrust the rest?"

"We shall only doubt each other, however, if we believe him," said William Burnham.

"Yet I will not say offhand that he lied," answered the Commodore.

Thus the cloud worked to bitterness from the outset. Four of the Seven, their hearts fouled by racial prejudice, swore that Cuffee was the culprit; while the Commodore supported poor Sam, and Stark staked his own honesty and honour upon the negro's. Acrimonious conversations passed among them, and it seemed that Commandant Cottrell had fully effected his purpose; but then came the awful weather, and certain necessary relaxations called for by its severity, now drew the old friends together again in hope of escape.

The cold had long reduced all exercise in the open, and through the greater part of every day the prisoners collected by thousands in the chambers immediately beneath the roof of each main building. Here, through the windows, a wide survey of the surrounding country offered, and Stark and his friends often noted the visible contours of the land, and realised to some extent the accuracy of Lovey Lee's maps. They learned also of a matter more interesting and nearer at hand. The boxes upon the inner wall were empty, for one soldier had already perished of frost-bite on sentry-go, and two others were at the door of death. To stand in the open air for half an hour was a proceeding so dangerous that the inner wall now remained unguarded save by its automatic protection of bells and wires.

Upon the occasion of the blizzard, while yet nature waited in frozen silence and the north grew black at midday, six of the Seven, taking their lives in their hands, made a second effort to escape. David Leverett alone had no share in the enterprise, for he was sick of a chill and kept his bed in the hospital. Burnham and Stark demurred whether they might in honour repeat their attempt without him, but Commodore Miller decided that the greatest good to the greatest number must determine their action. They were all sailors, and failing the apparatus of a wire ladder, employed in their first experiment, they designed a living ladder that could be quickly built up of their own persons. The manoeuvre was not difficult, and they practised it out of sight of the sentries until each man well knew his place and part in it.
