But still he kept on. Something drove him inexorably forward. For he was an engineer--and an American.
His next task was to fill the boiler. This he had to do by bringing water, two pails at a time from the spring. It took him three days.
Thus, after eleven days of heart-breaking lonely toil in that grimy dungeon, hampered for lack of tools, working with rotten materials, naked and sweaty, grimed, spent, profane, exhausted, everything was ready for the experiment--the strangest, surely, in the annals of the human race.
He lighted up the furnace with dry wood, then stoked it full of coal. After an hour and a half his heart thrilled with mingled fear and exultation at sight of the steam, first white, then blue and thin, that began to hiss from the leaks in the long pipe.
“No way to estimate pressure, or anything,” remarked he. “It's bull luck whether I go to hell or not!” And he stood back from the blinding glare of the furnace. With his naked arm he wiped the sweat from his streaming forehead.
“Bull luck!” repeated he. “But by the Almighty, I'll send that Morse, or bust!”

THE MOVING LIGHTS
Panting with exhaustion and excitement, Stern made his way back to the engine-room. It was a strangely critical moment when he seized the corroded throttle-wheel to start the dynamo. The wheel stuck, and would not budge.

Groaning, the wheel gave way. It turned. The engineer hauled again.
