"How strange!" pondered Harriet.

"A number of scientific men, passing through this section years afterward, unraveled the mystery. They say that the lime formation of the rocks, through which the water seeps into the lake, has poisoned the water. But you cannot make an Indian believe that."

"Ith thith a fairy thtory, or a really-truly thtory?" demanded Tommy.

"It is only a legend, Tommy," was Miss Elting's smiling reply.

"It has been a most interesting story," nodded Harriet. "I love Indian folklore."

"Girls, it is time for you to turn in," reminded Miss Elting.

"I don't like such stories before going to bed," objected Margery. "I know I shall have the nightmare. Oh!"

"We will roll you over if you do," answered Jane. "There's nobody but ourselves to hear you, either, so you may yell all you please, and——"

"No!" protested Tommy. "If Buthter yellth I'll yell, too, and wake up all the retht of you."

"Then you'll be attended to then and there," Jane warned her.
