Hazel said she would. Miss Elting also lay gazing up at the sky, following with her eyes the flight of the birds, many of which, high in the air, were soaring toward the east to meet the coming of the day.

Harriet picked up a boulder on her way to the Slide, and, reaching there, sent it spinning with the wrist movement peculiar to bowlers. The boulder skipped some rods out into the pond far below them before it sank under the water and disappeared, leaving a white trail in its wake.

"I can do that," declared Tommy Thompson.

Janus unwound himself from his blanket and stood with his hands in pockets, observing the jolly party.

"Don't lean over too far forward when you throw," warned Harriet.

"You jutht watch me. I'm going to make thith one thkip clear acroth the pond. Here it goeth. Oh, what a lovely Thlide!"

In her excitement, Tommy leaped to the end of the slippery course, jumping up and down. In her left hand she held another round stone ready to send it after the previous throw before the latter should have reached the pond. Margery was standing at hand ready to send hers down.

"Look out!" warned Harriet, who saw the danger of Grace's position. "Get back instantly!" Both she and Jane started on a run, fearing the result of Tommy's imprudence. But they were too late.

Tommy Thompson's feet slipped from under her. With a scream she plunged head first to the Slide, starting down it on her stomach.

"Catch her!" screamed Jane.
