The Confederate Worlds awoke to their danger at last. Was it too late? They sought in their museums and in the old archives of their early histories for plans of death-dealing devices that their own ancient, blood-thirsty ancestors had used. They discarded their foolish dreams of peace and selected the ideas for the most terrible weapons that they could find; and they began to manufacture these with lightning rapidity. Meanwhile, the inhabitants were conscripted, and the use of the weapons explained to them; and they were soon ready to be sent out against the invaders. The Twelve Confederate Worlds did not make the terrible mistake of under-rating their antagonists.
A GREAT force of invaders had surrounded Eelee, one of the largest cities on Titan, and were slowly forcing the weary defenders back. The invaders fought with swift, death-dealing weapons, while the defenders had only sticks and stones to oppose them. Was it any wonder that the dispirited inhabitants of Titan were being forced back on every hand?
The city of Eelee was full of weary, trembling fugitives who had fled before the invaders from the surrounding open country. The morale of the defenders was breaking. Time after time they tried to fight through the slowly tightening ring of those terrible two-legged invaders. The defenders were slaughtered in their thousands. They were driven back from every nook and cranny until they met in the center of their city. This could hardly be called their last stand: they were merely waiting their turn to be butchered. In one solid, compact mass they cowered in the public square in the center of the city. The only protection at their backs was a solidly built public building, Eelee's central station for wirelesstransmission of matter. Would help never come?
There came a shout of encouragement from the main wide entrance to the wireless transmission of matter building, and a solid line, some thirty deep. of fully armed Jovians from the four Confederate Worlds of Jupiter leapt out to attack. A wide avenue was immediately opened in the tightly packed mass of Eelee's cowering populace, and the Jovians leapt through and spread out fanwise in front of the defenseless inhabitants.
Each of the Jovians in the front lines carried on his back a small tank that sprayed out a hundred feet in advance a chemical, which ignited everything it touched and burnt with a hot, livid flame. Those behind them carried stubby metal tubes, which would bark with short, thunderous reports, and which left ruin and death in the ranks of the invaders.
Help had come in the blackest moment. Similar scenes were taking place in all of the larger cities on Titan.
Back, back they drove the invaders. The Twelve Confederate Worlds (now there were only nine, and two of those threatened with momentary extinction) hurled their conscripted forces across the void so swiftly and in such numbers that the invaders were startled. Reluctant to give ground that they had previously gained, the two-legged warriors contested desperately each inch of their retreat. From every direction they were met by the defenders, who were armed with weapons as good as their own.
Could these be the despised, peace-loving inhabitants of the solar system whom they had meant to destroy so as to have undisputed possession of the entire solar system? They could hardly believe it, for the once peaceful Jovians fought with a ferocity that was terrible.
Whenever the invaders stopped and tried to stand their ground, the defenders swarmed up; the chemicals sprayed fires upon the two-legged in-
