"Static electricity--always some form of electricity," said Asher grinning at the astonished oil baron. "Conductor coils here," he continued as he tapped the sealed cylinder, "are charged much as a flash-lamp battery. The charged conductors attract the static electricity of the air, and, in a manner similar to the action of the power generator, increase power. There is a slight difference: by turning quick power on my static gun, I can cause the charge to knock down and merely electrocute, as I knocked the half-melted tube from the table." "I can understand that, a little," Johns sighed profoundly. "It's the same juice that causes a gasoline truck to catch fire if you don't have a ground chain on it somewhere. But, just the same, I claim it's remarkable." "Not half as remarkable as what I expect to find two miles down when I descend to-morrow." Asher had a dreamy look in his eyes. "I wonder: new ways to get petroleum wealth ... a strange people...." * * * * * "Men,"--Asher, a tight-fitting asbestos composition suit covering him from foot to neck, spoke tersely--"when you get me on bottom, stop every bit of machinery, and don't dare pull up until I give the signal. If I'm down there the entire day, all right. But"--he smiled, trying to make light of the danger--"if I don't signal within thirty-six hours, pull up anyhow." From the bull-wheels of the drilling rig Asher spooled out some of the air-hose cable through which air blown over ice would be pumped into the Miner; then when the long steel cylinder was over the hole and ready, he turned to the company officials and government scientists and engineers around him in the boarded-up derrick. "Possibly I can get a survey in an hour. Perhaps I'll have to come back to the surface and make adjustments to my equipment. That remains to be seen.... Now, let's get low." He adjusted a helmet over his head. It looked much like the helmet worn by a sea diver, except that it had no connecting hose for air. The windows in the helmet, which contained pressure lights, worked on the same principle as the disintegrating rays of the Miner. When Asher turned the ratchet that set the little pressure machine into motion, a violet tinged green ray of great lighting power shot out and increased, by weight of air, or atmosphere beneath the earth, the power of one tiny spark a million times. Without ceremony or farewell, Asher crawled inside his tube. The door was closed and he fastened it from inside. For a moment, wild panic assailed him. But he fought it off, becoming again less the feeling human and more the cold calculator of advanced science. The light from outside, coming in through the windows of the Miner, was shut off. The long steel cage clanked against the sides of the special casing in the well, and Blaine Asher was on his trip into a lower world never before visited by man.
