At this question the native shrugged his shoulders and looked perplexed.

"I mean this man," went on the youth, and, taking the native by the hand, led him into the hut and up to the map on the wall. Instantly the face of Soko brightened.

"Yes, Soko know," he said. "Dat man come, so many time here——" He held up three fingers. "Look in ground, dig, not can find much, no. Go back to Sobago, so." And he made a dejected face, at which Roger and Phil had to laugh.

"He means Mr. Porter didn't locate the treasure," said the senator's son.

"Is that man in Sobago now?" went on Dave, paying no attention to his chum's remark.

"Yes, him at big town, Nanpi!"

"Good I Then I would like to get to Nanpi just as soon as I can," cried Dave, enthusiastically. "Will you take me there? I can pay you well," he added, for he still had his money belt and cash with him.

"Yes, can take to Nanpi," answered the native.

After that he explained that he and his companions had come to the island to hunt for some rare birds and for turtles. They were quite willing to return to Sobago Island immediately, if paid for so doing. A bargain was struck, and it was decided that the voyage should be begun in the morning. In the meantime all hands were to catch some fish and cook them, and also gather in a supply of other eatables. The natives had a number of hollow reeds with them, and these were filled with fresh water, just previous to setting out. It was calculated that, weather permitting, the distance would be covered in three days.

"These fellows know how to handle their big canoes very well," explained Captain Marshall. "They go out hundreds of miles, and sometimes weather the worst of storms. Occasionally, of course, they get swept away, but not often. They sail altogether by the sun and stars, and can strike almost as straight a course as if they were using a compass."
