“I have not been sure,” he was saying, “and I have told no one. I have been working on it for weeks, and I cannot make sure. Watch out for Knowlton. I suspect him. He knows the secrets of a score of our refuges. He carries the lives of hundreds of us in his hands, and I think he is a traitor. It’s more a feeling on my part than anything else. But I thought I marked a change in him a short while back. There is the danger that he has sold us out, or is going to sell us out. I am almost sure of it. I wouldn’t whisper my suspicions to a soul, but, somehow, I don’t think I’ll leave Chicago alive. Keep your eye on Knowlton. Trap him. Find out. I don’t know anything more. It is only an intuition, and so far I have failed to find the slightest clew.” We were just stepping out upon the sidewalk. “Remember,” Hartman concluded earnestly. “Keep your eyes upon Knowlton.”
And Hartman was right. Before a month went by Knowlton paid for his treason with his life. He was formally executed by the comrades in Milwaukee.
All was quiet on the streets—too quiet. Chicago lay dead. There was no roar and rumble of traffic. There were not even cabs on the streets. The surface cars and the elevated were not running. Only occasionally, on the sidewalks, were there stray pedestrians, and these pedestrians did not loiter. They went their ways with great haste and definiteness, withal there was a curious indecision in their movements, as though they expected the buildings to topple over on them or the sidewalks to sink under their feet or fly up in the air. A few gamins, however, were around, in their eyes a suppressed eagerness in anticipation of wonderful and exciting things to happen.
From somewhere, far to the south, the dull sound of an explosion came to our ears. That was all. Then quiet again, though the gamins had startled and listened, like young deer, at the sound. The doorways to all the buildings were closed; the shutters to the shops were up. But there were many police and watchmen in evidence, and now and again automobile patrols of the Mercenaries slipped swiftly past.
Hartman and I agreed that it was useless to report ourselves to the local chiefs of the secret service. Our failure so to report would be excused, we knew, in the light of subsequent events. So we headed for the great labor-ghetto on the South Side in the hope of getting in contact with some of the comrades. Too late! We knew it. But we could not stand still and do nothing in those ghastly, silent streets. Where was Ernest? I was wondering. What was happening in the cities of the labor castes and Mercenaries? In the fortresses?
As if in answer, a great screaming roar went up, dim with distance, punctuated with detonation after detonation.
“It’s the fortresses,” Hartman said. “God pity those three regiments!”
At a crossing we noticed, in the direction of the stockyards, a gigantic pillar of smoke. At the next crossing several similar smoke pillars were rising skyward in the direction of the West Side. Over the city of the Mercenaries we saw a great captive war-balloon that burst even as we looked at it, and fell in flaming wreckage toward the earth. There was no clew to that tragedy of the air. We could not determine whether the balloon had been manned by comrades or enemies. A vague sound came to our ears, like the bubbling of a gigantic caldron a long way off, and Hartman said it was machine-guns and automatic rifles.
And still we walked in immediate quietude. Nothing was happening where we were. The police and the automobile patrols went by, and once half a dozen fire-engines, returning evidently from some conflagration. A question was called to the fireman by an officer in an automobile, and we heard one shout in reply: “No water! They’ve blown up the mains!”
“We’ve smashed the water supply,” Hartman cried excitedly to me. “If we can do all this in a premature, isolated, abortive attempt, what can’t we do in a concerted, ripened effort all over the land?”
