This is the lost chamber, the secret of which had perished for well nigh a generation, till kindly fortune made it known to us.

All men think that the chamber lay in the portion of Chad that was destroyed in the late wars.

None dream it still exists.

But here it is, and Bertram has made out little by little exactly where it lies, and I will tell it thee.
"This portion at the lower and darker end is jammed in betwixt the ceiled roof of the great gun room and that attic chamber where the dry roots are stored away in the winter months before the frost binds them into the ground.

None enter that attic in the summertide save rats and mice, and though there may be many passing to and fro in the gun room, no sound from here can penetrate there; for we have tried times and again, when there has been none by to hear, if we can make each other hear sounds from either place.
