The Green Chapel

Then spurred he Gringolet, and betook himself along the path by the side of a wood, and rode over a rough hill into the valley. And he lingered there some time, and a wild place he thought it, for he saw no resting-place, but only high hills on both sides, and rough, rugged rocks and huge boulders, and the hill shadows seemed desolating to him. Then he drew up his horse, and it seemed wondrous strange to him that he saw not the Green Chapel on any side. At length a little way off he caught sight of a round hillock by the side of a brook, and there was a ford across the brook, and the water therein bubbled as though it were boiling. The knight caught up the reins and came to the hill, alighted, and tied up the reins to the rugged branch of a tree. Then he went to the hill and walked round about it, debating within himself what place it might be. It had a hole at the end and on either side, and it was overgrown with tufts of grass and was all round and hollow within. He thought it naught but an old cave or a crevice. Within and about it there seemed to be a spell. 'Ah lord,' quoth the gentle knight, 'Is this the green chapel?'
