But Jack and Mark were not much interested in the oil hunter's affairs. Only Jack remarked that he thought the fat man had been foolish to arm the Aleuts, or allow them to be armed. The Indians had evidently quite gone off their heads.
"They believe that we are spirits of the air," Professor Henderson told his friends. "That we are evil spirits. And I guess that Washington flying down upon them as he did will clinch that belief in their minds."
"Did you ever hear of anything like it before in all your days, Professor?" cried Jack. "Why, we can all jump like deer. I never saw anything like it."
Before the professor could reply there came a shout from the direction of the oil man's derrick. The two Aleuts, with their driver, had been working only a few moments at the auger. But perhaps the tool, so far down in the earth, had been ready to bite into the gas-chamber. There was a rumble from beneath that suggested to all that another 'quake was at hand. Then the Indians and the fat man started away from the derrick on the run.
The auger and piping shot out of the hole like stones driven by a catapult. Following the broken tools was a column of gas, gravel, water and mud that rose two hundred feet in the air. The earth trembled, and squawking like frightened geese, the Aleuts took to the tall timber, following the trail of their more fortunate comrades who had gotten away before. And they were not alone in their fright. The white men were likewise amazed and troubled by the marvelous geyser. It was as though the oil man had bored down to the regions infernal.
CHAPTER XIII
NATURE GONE MAD
The fat man came panting to the group surrounding Professor Henderson, just as fast as he could move his feet. And never before had the boys, or the professor, or Andy, or the black man beheld such an apparently heavy man get over the ground at such speed.
"A very mysterious thing," the professor was saying again—and he did not mean the roaring, spouting geyser that was shooting gas and debris a couple of hundred feet into the air.
Nor did he have time then to explain what seemed so mysterious to him. The descending debris threatened them all, and although they retired in a more dignified way than had the Indians from the vicinity of the spouting monster, they were all more or less disturbed by this new phenomenon.
