"A lot of good it'll do the old robber," growled Dick.
"He wants to know what it is," said Bulala.
"Tell him it's a bottle with something good to drink in it," snapped Doc. "Here, I'll show him how to get it out—looky, old tar-baby," and Doc stepped forward and removed the cap from the pen point. "Tell him," he explained to Bulala, "to put the shiny end in his mouth and then pull up this little lever here—that'll squirt the nice drink into his tummy."
Galla Galla did as Bulala directed. A peculiar expression overspread his evil face and then he commenced to spit, to the great astonishment not only of himself but of the assembled warriors, for Galla Galla was undeniably spitting blue. The effect upon him was astonishing and rather terrifying. He leaped about like a mad man, emitting strange noises which were interspersed with remarks that the boys were positive were not at all nice; but the remarkable part of the performance was that he vented all his rage upon Bulala, striking and kicking the poor fellow unmercifully.
"Tell him it won't hurt him," yelled Dick, fearful now of the results of Doc's joke. "Tell him white men drink it to make them strong," and when Bulala had succeeded in transmitting this information to Galla Galla the chief immediately calmed down and apparently was well pleased, though for a long time, thereafter, he continued to spit blue.
The boys had now emptied their pockets, but each clung to his knife, attempting to hide it from the eyes of the greedy Galla Galla. The attempt was vain; a filthy, pinkish palm was extended toward Doc who needed no one to interpret the cannibal's demands into gimme, gimme, gimme! It was then that an idea came to Doc that was little short of inspiration. His eyes snapped and sparkled.
"Why not?" he demanded aloud.
"Why not what?" asked Dick.
"Watch me!" cried Doc.
