IN THE OLD BEAR DEN

"Girls! Oh, girls!" shrieked Grace. "Walter is lost!"

She might have been foolish enough to try to draw in her pony; but Rhoda, riding close beside her, snatched the reins out of Grace's hand.

"More likely he thinks we are lost!" Rhoda exclaimed so that Grace, at least, heard her. Then she shouted to the others: "This way! This way!"

"Wha-at wa-ay?" demanded Bess Harley. "I—I'm going every-which-way, right now!"

But, in a very few minutes, it appeared that this sudden tempest was nothing to make fun over.

They stood there, the four ponies huddled together, in a whirl of dust and flying debris.

"Shout for him!" commanded Rhoda. "Don't cry, Grace. Walter is quite smart enough to look out for himself."

"Don't be a baby, dear," Nan said, leaning forward to pat Grace's arm. "He will be all right. And so shall we."
