A blush, a frown, a smile, chased one another across her face, but the smile remained.

"I am afraid you are as foolish as you are brave, Mr. Darcy," she said; "but I shall need an extra equerry, and if you would care to enter my service permanently, the place is at your disposal."

I fell again on my knee, mumbling my acknowledgments, for indeed I had not dared to look for so much.

There was a knock at the door, and Von Bieberstein entered.

"I have offered Mr. Darcy the position of equerry in my service," began the Princess, "and he has consented to fill it. Will you see that the necessary uniforms——"

"Of green and tan," I said, softly.

"What?" ejaculated Von Bieberstein.

"I ought perhaps to have said blue and gold," I answered, as I bowed my way from the room.

Von Bieberstein looked after me anxiously, but there was a smile on the Princess's face.

Such was the way in which I became equerry to a Princess in Green and Tan.
