"I see no harm in your telling Mrs. Eland," Ruth agreed. "Perhaps Mrs. Eland would go to see her, if it would do the poor thing any good."

"Why do you say 'poor thing' about Miss Pepperill, Ruthie?" demanded Dot, the inquisitive. "Has she lost all her money?"

"Goodness me! no, child," replied the oldest Corner House girl; nor did she explain why she had said "poor thing" in referring to the sick teacher. But everybody was saying the same; they did not expect her to live.

The substitute teacher who took Miss Pepperill's place in school had possibly been warned against Sammy Pinkney; for that embryo pirate found, at the end of the first day of such substitution, that he was no better off than he had been under Miss Pepperill's régime.

Tess was very serious these days. She was troubled about the teacher who was ill (for it was the child's nature to love whether she was loved in return or no), her lessons had to be kept up to the mark, and, in addition, there was her part as Swiftwing.

She knew her steps and her songs and her speeches, perfectly. But upon the Saturday morning when the dances were rehearsed, Tess found that there was more to the part than she had at first supposed.

There was to be a tableau in which—at the back of the stage—Swiftwing in glistening raiment, was the central figure. A light scaffolding was built behind a gaudy lace "drop" and to the steps of this scaffolding, from the wings on either side of the stage, the birds and butterflies flew in their brilliant costumes to group themselves back of the gauze of the painted drop.

Tess was a bit terrified when she was first taken into the flies, for Swiftwing first of all was to come floating down from above to hover over and finally to rest upon a great carnation.

Of course, Tess saw that she was to stand quite securely upon the very top step of the scaffolding. A strong wire was attached to her belt at the back so that she could not possibly fall.

Below, and on either side of Tess, was a smaller girl, each costumed as a butterfly. These were tossed up to their stations by the strong arms of stage-hands. They could not be held by wires as Tess was, for their wings were made to vibrate slowly all through the scene.
