“They saw the blowout on the surface, blowing muck and spray forty feet into the air when it first holed through. They went as close as they dared to the rising bubbles then and were right on the spot when Fighting Jack came by. Rose right up into the air, they said, and they had him almost as soon as he fell back. Unconscious and undamaged and when he came to he was cursing even before he opened his eyes. Now back to the job, men, we have twelve feet more to go today.”

As soon as the rhythm of the work had resumed, Captain Washington turned to Drigg and put out his hand in a firm and muscular handshake. “It is Mr. Drigg, isn’t it? The marquis’s private secretary?”

“Yes, sir, and Secretary of the Board as well.”

“You have caught us at a busy moment, Mr. Drigg, and I hope you were not alarmed. There are certain inherent difficulties in tunneling but, as you have seen, they are not insurmountable if the correct precautions are taken. There is a trough in the ocean bottom above us at this spot, I doubt if more than five feet of sand separate us from the water. A blowout is always a possibility. But prompt plugging and the use of the Gowan stabilizer quickly sealed the opening.”

“I’m afraid it is all beyond me,” said Drigg.

“Not at all. Simple mechanics.” There was a glint of true enthusiasm in Captain Washington’s eye as he explained. “Since the sand is water-soaked above us the compressed air we use to hold back the weight of the water blew an opening right through to the sea bottom. The wooden barricade sealed the opening temporarily while the Gowan stabilizer could be brought up. Those drills are hollow and as soon as they were driven home liquid nitrogen was pumped through them. This fluid has a temperature of 345.5 degrees below zero and it instantly freezes everything around it. The pipe you see there pumped in a slurry of mud and water which froze solid and plugged the opening. We shall keep it frozen while we tunnel past this dangerous area and seal it off with the castiron sections of tunnel wall. All’s well that ends well—and so it has.”

“It has indeed, and for your head ganger as well. How fortunate the boat was nearby.”

Washington looked at the other keenly before answering. “Not chance at all as I am sure you know. I do believe the last letter from the directors drawing my attention to the wasteful expense of maintaining the boat at this station was over your signature?”

“It was, sir, but it appeared there only as the drafter of the letter. I have no responsibility in these matters being just the vehicle of the directors’ wishes. But with your permission I shall give a complete report of what I have seen today and will stress how a man’s life was saved because of your foresight.”

“Just good engineering, Mr. Drigg.”

“Foresight, sir, I insist. Where you put a man’s life ahead of money. I shall say just that and the matter will be laid to rest once and for all.”

Washington seemed slightly embarrassed at the warmth in Drigg’s voice and he quickly sought to change the subject.

“I have kept you waiting too long. It must have been a matter of some importance that has brought you personally all this distance.”

“A communication, if you please.” Drigg unlocked the portfolio and took out the single envelope it contained. Washington raised his eyebrows slightly at the sight of the golden crest, then swiftly broke the seal and read the letter.

“Are you aware of the contents of this letter?” asked Washington, drawing the folded sheet of paper back and forth between his fingers.

“Only that the marquis wrote it himself and instructed me to facilitate in every way your return to London on a matter of some importance. We will be leaving at once.”

“Must we? The first through connection on an up train is at nine and it won’t arrive until the small hours.”

“On the contrary,” Drigg said, smiling. “A special run of The Flying Cornishman has been arranged for your convenience and should be now waiting.”

“It is that urgent then?”

“The utmost, his lordship impressed that upon me most strongly.”

“All right then, I will have to change…”

“Permit me to interrupt. I believe instructions were also sent to the head porter of your hotel and a packed bag will be awaiting aboard the train.”

Washington nodded acceptance; the decision had been made. He turned about and raised his voice over the growing din. “Bullhead. You will be head ganger here until Fighting Jack returns. Keep the work moving.”

There was no more to be done. Washington led the way back through the shield to the electric locomotive which he commandeered for the return trip. They took it as far as the bulkhead and arrived just in time to meet Fighting Jack emerging from the air-lock door.

“Damn me if I want to do that again,” he bellowed, his clothes still dripping wet, bruises on his head and shoulders where he had been dragged through the ocean bottom. “Like a cork in a bung I was, stuck and thought it me last moments. Then up like a shot and everything getting black and the next I know I’m looking up’t‘sky and at the faces of some ugly sinners and wondering if I were’t’heaven or the other place.”

“You were born to be hanged,” said Washington calmly. “Back to the face now and see they work the shift out without slackening.”

“I’ll do that and feed any man who shirks into a blowout and up the way I went.”

He turned and stamped off while they entered the air lock and found seats.

“Should he be working . .?” Drigg ventured after long minutes of silence.

“He shouldn’t—but I cannot stop him. These navvies have a way of life different from ours and we must respect it. If he’s hurt, or has the bends, he would never admit it and the only way to get him to a hospital would be to bash him over the head and he would never forgive me. I have seen these men, on a dare, jump over the open mouth of a ventilation tunnel ten feet wide and a hundred feet deep. I have seen three men in a row fail and fall to their deaths and the fourth man, laughing, succeed. Then he and all the others there go out and drink beer until they can no longer walk in memory of their dead buddies. And no one regretting or worrying about a thing. A hard and brutal life you might say, but, by God, it makes men.”

As though ashamed of this emotional outburst, Washington kept his counsel for the rest of the trip out of the tunnel, until they reached the platform in Penzance. It was dark now with the last bars of red fading from the clouds in the west. Lights were winking on all over the expanse of tracks as the yardboys went about refilling the switch beacons with paraffin and lighting their wicks. The crowds were gone, the station silent, while the solitary form of the Dreadnought bulked even larger than life with its newly polished golden cladding catching and holding the red and green of the switch lights. There were only two carriages attached, the Saloon Car and Monarch of the Glens, the private coach used only by the marquis or other members of the board of directors: The porter for this car, an elderly white-haired man named Walker, formerly the butler of one of the Board members, now retired to this sinecure in his advancing years, was waiting at the steps to the car.

“Your bath is drawn, sir, and your clothing laid out.”

“Capital—but I must have a drink first. Join me if you will, Mr. Drigg, it has been a long and hot day with more than enough excitement for a month.”

“A pleasure.”

The gaudily uniformed boy was on the door to the Saloon Car, smiling as he drew it open for him. Washington stopped short when he saw him. “Should not this infant be in bed? Goodness knows we can open the door ourselves on this special trip.”

The child’s face fell and his lower lip showed a tendency to wobble before Drigg spoke. “They are volunteers all, Captain Washington, Billy here along with the rest. They want to go, you must understand that.”
