Pepe slipped out of the boat and began to wade ashore. When the iguana raised itself on short, stumpy legs George shot at it, and missed, as usual. But he effectually frightened the reptile, which started to climb the bank with much nimbleness. Pepe began to run, brandishing his long _machete_. George plunged into the water in hot pursuit, and then Hal yielded to the call of the chase. Pepe reached the iguana before it got up the bank, aimed a mighty blow with his _machete_, and would surely have cut the reptile in two pieces if the blade had not caught on an overhanging branch. Then Pepe fell up the bank and barely grasped the tail of the iguana. Pepe hauled back, and Pepe was powerful. The frantic creature dug its feet in the clay-bank and held on for dear life. But Pepe was too strong. He jerked the iguana down and flung it square upon George, who had begun to climb the bank. George uttered an awful yell, as if he expected to be torn asunder, and rolled down, with the reptile on top of him. Ken saw that it was as badly frightened as George. But Hal did not see this. And he happened to have gained a little sand-bar below the bank, in which direction the iguana started with wonderful celerity. Then Hal made a jump that Ken believed was a record. Remarkably awkward as that iguana was, he could surely cover ground with his stumpy legs. Again he dashed up the bank. Pepe got close enough once more, and again he swung the _machete_. The blow cut off a piece of the long tail, but the only effect this produced was to make the iguana run all the faster. It disappeared over the bank, with Pepe scrambling close behind. Then followed a tremendous crashing in the dry thickets, after which the iguana could be heard rattling and tearing away through the jungle. Pepe returned to the boat with the crestfallen boys, and he was much concerned over the failure to catch the big lizard, which he said made fine eating. “What next?” asked George, ruefully, and at that the boys all laughed. “The fun is we don’t have any idea what’s coming off,” said Hal. “Boys, if you brave hunters had thought to throw a little salt on that lizard’s tail you might have caught him,” added Ken. Presently Pepe espied another iguana in the forks of a tree, and he rowed ashore. This lizard was only a small one, not over two feet in length, but he created some excitement among the boys. George wanted him to eat, and Hal wanted the skin for a specimen, and Ken wanted to see what the lizard looked like close at hand. So they all clamored for Pepe to use caution and to be quick. When Pepe started up the tree the iguana came down on the other side, quick as a squirrel. Then they had a race round the trunk until Pepe ended it with a well-directed blow from his _machete_. Hal began to skin the iguana. “Ken, I’m going to have trouble preserving specimens in this hot place,” he said. “Salt and alum will do the trick. Remember what old Hiram used to say,” replied Ken.
