Seating himself in an upholstered chair, he prepared for quick and decisive action. With one hand he pulled down the “Helicopter” lever, and, through the “Electro-visional,” saw a huge, “Electro re-tempered” steel solid corkscrew-like device with a “screw” fifty feet deep in the groove, shoot into the air. Setting its regulator at “Half-speed,” he touched a button and began to ascend slowly. When the “Altitude Indicator” registered “1000 Feet,” he turned “full speed” into the helicopter device and finished with a rush. At “20,000 Feet” he shut the helicopter down to “Maintenance of Altitude” speed, pulled a lever which released a huge propeller from its underneath pocket, and set it going at full speed “In Reverse,” yanked the lever back at “21,500 Feet,” and came to a full stop at “22,000 Feet” with the underneath propeller roaring noisily but harmlessly in its enclosed pocket. Turning to the “Electro-visional” dial, he threw the clutch into the “3670 Mile” circuit, picked out the faint outline of the higher peak of Mt. McKinley, and stuck a needle-point into it. This he connected, by means of a delicate copper wire, with “Local”--which he knew was permanently connected in a similar manner with the gigantic dynamo at Niagara Falls--set the regulator of his “Electric-flash” at “.017 Seconds,” pushed a button which shut off the helicopter, yanked back the lever which collapsed it into its overhead pocket; and, as he heard the heavy copper plates bang shut over all, he closed his eyes and touched the final button. Then, in spite of all precautions, he was nearly blinded by the vivid lightning that enveloped the entire machine; and, notwithstanding the intricate system of “Shock Absorbers,” he thought for a moment that he had been yanked in two as he was shot through space at the rate of 186,000 miles per second. And then, as if it was a reflex of the original yank, came the answering “tug” of the rear propeller as it automatically shot out of its pocket going full speed “In Reverse.” Opening his eyes with nerves taut for the crucial moment, he reached for the “Plane-wing” lever with one hand, and glanced at the “Speedometer” for the indication of the moment when it would be safe, and necessary, that he throw-out his biplane-wings of “Electro re-tempered” steel with a “spread” of one hundred and fifty feet. Then, suddenly, the dual peaks of Mt. McKinley appeared directly in front of his “Electro-visional”; and, throwing caution to the winds, he yanked down the “Plane-wing” lever, and heard the rattle and bang of the adjustments, and saw that the apparatus was withstanding a severer test than it was guaranteed for.
