"There!" exclaimed Miss South as Julia had finished, "I have an idea; come with me."

It was late and the pupils had all gone to bed, and Concetta, hearing unwonted steps going to the upper story, pushed her door open a little, and was surprised to see the strange procession winding upwards.

It took its way to the end room in the attic, and when she had lit the gas Miss South asked Anstiss to help her lift out a chest from a corner of the closet. Selecting a small key from her ring and opening the trunk, she began to unfold one or two garments.

"Oh, how beautiful! But who could have worn it?" exclaimed Julia, as a velvet gown trimmed with ermine and with a long train unfolded itself before them.

"Ah, but this is lovelier!" she added, as a dove-colored brocade with pattern outlined in pink was shown, intended evidently to be worn with the pink satin petticoat that accompanied it. Further delving into the trunk brought out pointed shoes, elaborate head-dresses, and other fantastic things.

"Did your grandmother ever wear these clothes?" asked Anstiss in surprise. "I should hardly think that they were of the style even of her day."

"Oh, these things are intended for costume parties," returned Miss South. "My grandmother described some of the occasions when she first wore them abroad. She took the greatest care of them, and every spring she herself supervised her maid when she shook them and did them up again in camphor. Strangely enough I have been so busy the past year that I had forgotten about these particular things. There are two complete costumes. One of them is entirely in the period of the Festival, and the other needs so little alteration that you and Pamela, Julia, will be completely equipped, with almost no thought in the matter."

"But why won't you go yourself?"

"I have quite made up my mind about that; for the present, at least, I have no desire for gayety."

It was really amazing that these two costumes should have been found so perfectly to meet all the requirements of the Festival. Julia, of course, could have had a costume especially designed for her by a costumer, but as she had said, in talking it over with Brenda, she was by no means in the mood for this, and she would have stayed home rather than waste the time in this way.
