The Blue Knight, feeling sorry for the poor witless fellow, labored earnestly with him, giving him long explanations, telling him the same things again and again, and showing him better ways of doing his work with the horses and about the stalls.

And Klaus Klodrian, as the day wore on, really began to show a little comprehension. He laughed so heartily over it all, that it seemed as if his wide mouth really did stretch from ear to ear.

As for the Blue Knight, he became so absorbed in trying to teach Klaus, that the long summer day was neither tiresome nor unhappy. Twice during the day had he seen the Princess and the Green Knight walking together in the castle garden. They talked and laughed, and seemed, he thought, to have become exceedingly good friends. So also thought the Duke, and he remarked upon it to the Wise One who, in his evening walk, came past the castle.

"Ah, but this Green Knight is a magnificent fellow," said the Duke. "And he is very talented. He will gain the Princess. They are already excellent friends, and I am greatly prejudiced in his favor. He is really charming! You should have heard the good stories he told to-day when we were dining. Yes, he will certainly gain the Princess."

KLAUS BROUGHT FORTH HIS ONLY TREASURE.

"To-day he is sailing with the wind," said the Wise One. "Let us see him to-morrow when the wind is against him."

The sun had gone down and darkness had spread itself all around, but the castle was brilliantly illuminated, and from its windows the light streamed out, while soft strains of music floated through the halls and into the summer air. There was a ball at the castle.

Thoughts of the lovely Princess had been present with the Blue Knight all the day long, no matter how intently he was laboring with Klaus; so when evening came he sought to get just a glimpse of her through the castle window.
