Great minds generally think in company, and often hit upon the same invention at the same moment, so perhaps all four girls had an equal share in the brain-wave. They communicated it cautiously to companions, and as it "caught on" they sounded Mrs. Best, and finding her favorably disposed to the scheme, begged her to intercede for them with Miss Burd. The head-mistress was wonderfully gracious about the matter, gave full permission for the dance, promised to be present herself, and allowed the invitation to be extended to any mistresses and seniors who would care to join the party. It was quite a long time since the hostel had had any particularly exciting doings, so that the girls flung themselves into their preparation with much enthusiasm. Those who were lucky enough already to possess fancy costumes, or who were able to borrow them, of course scored, and the rest set to work to manufacture anything that came to hand. It was to be in the nature of an impromptu affair, but a few days' notice was given, and the girls were able to devote a Saturday to the all-absorbing problem. Ingred, home for the week-end, enlisted the help of Mother and Quenrede, and turned the bungalow almost upside down in her quest for suitable accessories. She thought of a number of characters she would have liked to impersonate, but was always balked by the lack of some vital article of dress.

"It's no use!" she lamented. "I can't be 'Joan of Arc' without a suit of armor, or 'Queen Elizabeth' when I haven't a flowered velvet robe! I'm so tired of all the old things! It's too stale to twist some roses in my hair for 'Summer,' and I've been a gipsy so often that everybody knows my red handkerchief and gilt beads. I'd as soon be a Red Indian squaw!"

"And why shouldn't you be?" asked Quenrede. "It's a remarkably pretty costume."

"Oh, I dare say, if I could beg, borrow, or steal it!"

"You've no need to do either, my dear. I've had a brain-wave, and we'll fix it up for you at home. Yes, I mean it! Allow me to introduce myself: 'Miss Quenrede Saxon, Court Costumier. The very latest theatrical productions.' I'll make you look so that your own mother will hardly know you!"

"I'd like to puzzle them!" rejoiced Ingred. "Miss Burd said she should have a parade, and hinted something about a prize. They always give points to whoever has the best disguise. Masks are barred, but we may paint our faces. I think I shall be rather choice as a squaw!"

"You ought to have me with you as your 'brave'!" chuckled Hereward.

"It's a 'Ladies Only' dance, so you can't be invited, my boy! There won't be a solitary masculine individual present—even the gardener will have gone home."

"You bet folks will peep in!"

"No, they won't. The premises are strictly private."
