"I offer you your lives," Kram said almost nonchalantly.

"As a man of my intellect—" Xenthl declared after a breath-take of hesitation, "I require whatever attempt at proof you may have for your childish statements. Guard!"


Within moments, the rifle was in the hands of one of Xenthl's marksmen, and, sighting with a headquarters electrono-telescope, the soldier from Sirius drew a bead on the drifting cruiser hulls, and pressed the curved trigger at Xenthl's order.

In a visiplate, Xenthl himself witnessed an incredible white flash as first one of the space-cruiser hulls was blown to atoms, and then in rapid succession, the second, third, fourth, and fifth.


The first space-cruiser hull was blown to atoms....


"You will observe," Kram said, "that only one hull was hit. But all were destroyed. A little chain-reaction gadget I developed last week—" A gasp at Kram's elbow; but Kram had not finished—"You have observed also," he continued matter-of-factly, "that with one blast of only a rifle, to say nothing of the cannon I have also developed, a myriad of targets may at once be destroyed. Your G-ray," Kram adopted a tone dripping with respect, "is capable, after all, of destroying but one target at a time."
