They could see men upon the sloping roofs, gradually sloping from a central ridge, men like great flies, nailing tanned hides over the beams. The sound of tapping hammers reached them from the work which should be protective of Greek fire and burning tar from above.

And against the light green of the meadow-lands, and the darker olive of the thick forest trees, the many colours of pennons, the glint of sunlight upon arms, gave the animation of the scene an added quality of picturesqueness. How "decorative" it all was! how vivid and complete a picture! And yet how stern and sinister in meaning.

"Bella premunt hostilia,

Da robur, fer auxilium."

The soldiers were silent as they leaned out over the pent-house. Huber crossed himself, for the chapel bell began to toll down below in the fortress.

The squires left the works and descended to the bailey. Huber remained on the wall. From where he stood he could see all over the castle. Such of the garrison as were not on guard or employed in active preparation straggled slowly over the grass towards the chapel door. Some of the serfs followed, the man-at-arms could easily distinguish their characteristic dress.

He turned curiously pale beneath his bronze. Then his eyes turned towards the noble tower Outfangthef, and presently fixed themselves on a low iron door, between two buttresses, which was nearly below the level of the yard, and must be reached by a few old mildewed steps.

His eyes remained fixed upon the archway of the door, and his face became full of a great gloom and horror.

The sentinels passed and re-passed him as he stared down below with set pale features. At length he turned and entered one of the hoards. The angle of the side hid him from view of the men upon the walls.

There Huber knelt down and prayed for the serf who had saved his life on Wilfrith Mere, and now lay deep down behind that iron door.
