"Foot? No," he replied. "Fool that I was not to have thought of it before. Look at the knife!"

The steel was deeply embedded in the floor.

I descended from the farmer's shoulders, and stood by while the colonel directed a man to remove the thick deposit of dust that everywhere covered the floor of the tunnel. This done, a square of wood with a rusted iron ring in its centre was laid bare.

"'Tis evident we must go down ere we go up!" remarked Firestone, with a laugh. "Now—pull together!"

Accordingly, the big farmer and another strong yeoman tugged at the ring, but the next instant they were sent crashing into the stone wall of the tunnel, which alone saved them from falling backwards, with the rusted iron held firmly in their hands.

"It has broken off short we must be careful lest we are unable to make use of what is left in the ring," cautioned the colonel, and directing the men to secure a better grip of the fragment of iron that still remained in the slab by means of a strip of cloth, while others used their weapons as levers, the barrier between us and freedom was removed.

Another short flight of steps, followed by a passage less than twenty feet in length and lower than the one we had just traversed, terminating in a spiral staircase.

At the top of these steps was a massive stone slab, balanced on a heavy iron pivot, while two strong bolts kept it in position, so that it could not be moved, save from the side on which we were.

Remembering that extreme caution was necessary, we carefully withdrew the bolts, and slowly pushed the stone, Without a sound, the whole slab turned easily on its pivot, and, to my great surprise, I found that we were looking into a building, while my astonishment was even greater when I discovered it was none other than Chalton Church!

Many a time had I noticed a large tomb in one corner of the church, with a brass showing the effigy of a knight with his legs crossed at the knees and his feet resting on a lion, while I had often tried to decipher the almost illegible writing, "Ci gist..." But up to that very moment I had not the faintest idea, nor had anyone else in or around Chalton, I feel certain, that the tomb was in reality not a tomb, but the egress from a secret tunnel from Ashley Castle.
