Grace thrust her bare arms through the sheet of water pouring from above, groping for the rocks behind.

Sharp screams, at first loud and piercing, an instant later muffled and seeming far away, brought Elfreda to her feet. Grace was nowhere to be seen.

"Help! Grace has gone in!" shouted Elfreda, plunging into the cold water.

CHAPTER XX

CONCLUSION

Hippy heard. Hi, farther away, heard. Both ran through the bushes.
Anne, Nora, and Emma sped to the stream.

Hippy and Elfreda were searching the bottom of the stream, which was not more than three feet deep. Hi stopped them and asked Elfreda to tell what she knew.

"Both hands were thrust through the fall like this," and Elfreda thrust her own hands through the sheet of water. "I was looking at the map when I heard her scream. Looking up, she had disappeared."

Lang nodded and plunged through the waterfall. Those on the outside heard a shot, followed almost instantly by a second one. At the sound Elfreda and Hippy plunged through the fall. Near the base of the fall was no wall of rock behind the water. Instead, a tunnel-like cave led into the mountain. Elfreda gasped and Hippy looked in amazement. Grace lay on the floor of the cave and Hi Lang had a man flown and was beating him, while a little girl was trying to aid the man by striking Hi over the head and shoulders with a stick.

Wingate snatched the stick from her. The child shrank back, and
Hi, realizing that he was going too far, ceased beating the man.
