Loaded down with Delgonian weapons, they hurried back the way they had come. Much to Kinnison's relief he found that his forebodings had been groundless; the batteries were still there, still absorbing myriawatt hour after myriawatt hour from the Delgonian generators. Staring fixedly at the innocuous-looking containers, he frowned in thought.

"Better we insulate those leads a little heavier and put the cans back in our armor," he suggested finally. "They'll charge just as well in place, and it doesn't stand to reason that this drain of power can go on for the rest of the night without somebody noticing it. And when that happens those Overlords are bound to take plenty of steps—the nature of none of which we can even guess at."

"We must have power enough now so that we can all fly away from any possible trouble," Worsel suggested.

"But that's just exactly what we are not going to do!" Kinnison declared, with finality. "Now that we've found a good charger, we aren't going to leave it until our accumulators are chocka-block. It's coming in faster than full draft will take it out, and we're going to get a full charge if we have to stand off all the vermin of Delgon to do it."

Far longer than Kinnison had thought possible they were unmolested, but finally a couple of Delgonian engineers came to investigate the unprecedented shortage in the output of their completely automatic generators. At the entrance they were stopped, for no ordinary tools could force the barricade VanBuskirk had erected behind that portal. With leveled weapons the patrolmen stood, awaiting the expected attack. But none developed. Hour by hour the long night wore away, uneventfully. At daybreak, however, a storming party appeared and massive battering-rams were brought into play.

As the dull, heavy concussions reverberated throughout the building the patrolmen each picked up two of the weapons piled before them and Kinnison addressed the Velantian.

"Drag a couple of those metal benches across that corner and coil up behind them," he directed. "They'll be enough to ground any stray charges. If they can't see you they won't know you're here, so probably nothing much will come your way direct."

The Velantian demurred, declaring that he would not hide while his two companions were fighting his battle.

But Kinnison silenced him fiercely. "Don't be a fool!" the Lensman snapped. "One of these beams would fry you to a crisp in ten seconds, whereas the defensive fields of our armor could neutralize a thousand of them, from now on. Do as I say, and do it quick, or I'll beam you unconscious and toss you in there myself!"
