“Just wait, Hal,” put in George, grimly. “Just wait. It’s coming to him!” The boys slept well the remainder of the night and, owing to the break in their rest, did not awaken early. The sun shone hot when Ken rolled out; a creamy mist was dissolving over the curve of the mountain-range; parrots were screeching in the near-by trees. After breakfast Ken set about packing the boat as it had been done the day before. “I think we’ll do well to leave the trunk in the boat after this, unless we find a place where we want to make a permanent camp for a while,” said Ken. Before departing he carefully looked over the ground to see that nothing was left, and espied a heavy fish-line which George had baited, set, and forgotten. “Hey, George, pull up your trot-line. It looks pretty much stretched to me. Maybe you’ve got a fish.” Ken happened to be busy at the boat when George started to take in the line. An exclamation from Pepe, George’s yell, and a loud splash made Ken jump up in double-quick time. Hal also came running. George was staggering on the bank, leaning back hard on the heavy line. A long, angry swirl in the pool told of a powerful fish. It was likely to pull George in. “Let go the line!” yelled Ken. But George was not letting go of any fish-lines. He yelled for Pepe, and went down on his knees before Pepe got to him. Both then pulled on the line. The fish, or whatever it was at the other end, gave a mighty jerk that almost dragged the two off the bank. “Play him, play him!” shouted Ken. “You’ve got plenty of line. Give him some.” Hal now added his weight and strength, and the three of them, unmindful of Ken’s advice, hauled back with might and main. The line parted and they sprawled on the grass. “What a sockdologer!” exclaimed Hal. “I had that hook baited with a big piece of duck meat,” said George. “We must have been hooked to a crocodile. Things are happening to us.” “Yes, so I’ve noticed,” replied Ken, dryly. “But if you fellows hadn’t pulled so hard you might have landed that thing, whatever it was. All aboard now. We must be on the move--we don’t know what we have before us.” When they got into the boat Ken took the oars, much to Pepe’s surprise. It was necessary to explain to him that Ken would handle the boat in swift water. They shoved off, and Ken sent one regretful glance up the river, at the shady aisle between the green banks, at the white rapids, and the great colored dome of the mountain. He almost hesitated, for he desired to see more of that jungle-covered mountain. But something already warned Ken to lose no time in the trip down the Santa Rosa. There did not seem to be any reason for hurry, yet he felt it necessary. But he asked Pepe many questions and kept George busy interpreting names of trees and flowers and wild creatures.
