to determine if there was any sign that our craft had been sighted in descent. Evidently, the population of the vicinity was so small that our plans were successful. Our patrols reported only one small group of Earthlings in the immediate area. Deciding to test the new weapons on this gathering, we disembarked a force of a dozen warriors, all disguised as Earthlings and with myself as commander and Baren Darl as our technical advisor. "We must keep our senses alert for Sam Spade, Superman and the Lone Ranger," Baren Darl said nervously, peering around among the strange exotic trees and other vegetation that grows on Earth. I was somewhat surprised at his tone and obvious unease. "Who?" I asked. "What?" "Three Terran warriors of amazing ability and viciousness," he told me. "I have been gathering reports of their activities from the radio for some time. They seem to have clairvoyant minds; one or the other of them almost invariably appears on the scene of violence." I said impatiently, "Without doubt, our weapons would mean the end of these warriors." I did not share his belief that any Earthling warriors might be our equals or superiors, but to remain on the cautious side, I immediately ordered that the Elect-no be switched on. This weapon, one of the several designed for the Earth campaign, as your Omnipotence is undoubtedly aware, is so constructed as to prevent the use of any internal combustion engine within a dozen miles of the Elect-no. In this case, no aircraft, nor landcraft, utilizing internal combustion, could enter our zone. Baren Darl seemed somewhat relieved at this precaution, but his attitude to a certain extent began to affect the rest of us. To prepare for any eventuality, I had the Fission-Suppressor activated. This, of course, automatically made it impossible for nuclear fission to take place within a hundred miles of our ship. That measure pleased Baren Darl exceedingly in view of the fact that the Earth nations seemed to be spending practically all of their military appropriations on their so-called A-Bombs and H-Bombs. According to the radio emanations our Luna base had picked up, the Earthlings were interested in little else in a military way, except possibly bacteriological weapons, and, of course, we were prepared to deal them a strong blow along that line
