"No!"—"No!" broke in both girls indignantly, while Ruth, looking as if she would like to box Thure's ears, declared:
"We girls can keep a secret just as well as you boys can, and you know it; for, haven't we saved you from many a licking by not telling your dads what you had been up to? But if this is the way you are going to treat us, we'll fix you next time," and she shook her head threateningly.
"Besides," supplemented Iola triumphantly, "we know most of the secret already. It's about a Cave of Gold and a map and—"
"Oh, Christmas! You couldn't keep nothing from the girls!" and the face Thure turned to Bud showed his disgust.

"And now," concluded Thure excitedly, when the last of the wonderful tale had been told, "Bud and I must both start for the mines just as soon as we can get ready; and get father and Rex and Dill and Uncle Frank and Hammer Jones to help us find this Cave of Gold; and when we have found it—"
