A shot, followed by a howl from Woo Smith, caused the two men to redouble their efforts. Hippy finished dressing first and ran out, rifle in hand, just as the guide came running up.

“Me savvy tlouble. Plenty men come ’long.”

“How many?” interjected Tom.

“Sees.”

“Six, eh? We ought to be able to handle them,” answered Hippy.

“There probably are more than six. What shall we do?” questioned Grace.

“All hands get inside the cave. From there we can watch the lake, and at the same time be fairly well protected,” directed Hippy.

Acting upon a hail from Tom that he was ready, the Overlanders hastened into the cave, where Woo was questioned in detail as to what he had observed. Having obtained all the information that the guide had to give, Hippy and Tom crept out, and lay secreted in the bushes in front of the cave to guard against surprises.

They had been there but a short time when Lieutenant Wingate discovered a man on the rocks about a hundred yards to the right of them. At almost the same instant Tom Gray nudged his companion.

“Two men are over in our camp,” he whispered.
