There was something beside this conflict that Burl and Saya should have noticed, but they were instantly intent. The other thing was quite unparalleled. There had been nothing else like it on this planet in many hundreds of years. It moved slowly above the plateau as if examining it. It was half a dozen miles away and perhaps a mile higher when Burl and Saya prepared to intervene professionally on behalf of the dogs. Then it swerved and moved directly toward them. It moved swiftly. But it was silent, and they did not know at all. Burl leaped in with a lance-thrust at the tough integument where an armored leg joined the body. He missed, and the monster whirled. Then Saya flashed her cloak before the beetle, so that it seemed a larger and nearer antagonist. As the creature whirled again, Burl thrust once more and a hind-leg crumpled. Instantly the thing limped crazily. A beetle does not use its legs like four-legged creatures. It moves the two end legs on one side with the center leg on the other, so that always it is braced on an adjustable tripod. But it cannot adjust readily to crippling. A dog snatched at a spiny lower leg and crunched and darted away. The expressionless, machine-like horror uttered a formless, deep-bass cry and was spurred to all possible ferocity. The fight became a thing of furious movement and uproar, with Burl striking once at a multiple eye so the pain would deflect it from a charge on Saya, and Saya again deflecting it with her cloak and once breathlessly trying to strike it with her shorter spear. Then the beetle sank to the ground, all three legs on one side crippled. The remaining three thrust and thrust and struggled terribly and suddenly it was on its back, still striking its gigantic jaws frantically in the hope of murder. But Burl stabbed home between two armor-plates where a ganglion was almost exposed. A thrust killed it instantly. Burl and Saya smiled at each other. There was a monstrous sound of splintering trees. They whirled. The dogs pricked up their ears. One of them barked defiantly. * * * * * Something huge--truly huge!--settled to the ground a bare hundred yards away. It was metal, and there were ports, and it was utterly beyond experience, because, of course, there had been no spaceship landings on this planet in forty-odd human generations. But as Burl and Saya stared blankly at it, a port opened, and men came out, and they waved hopefully to the two barbarically attired figures who had been seen fighting a monster with the help of dogs. Which meant some sort of civilization. The dogs confirmed it. They sniffed. These, also, were men. And Burl and his tribe had this smell, and were friends. So the dogs trotted forward with the self-confident cordiality of dogs on excellent terms with men--and there was no question of friendship. None at all. The men came forward joyously to talk to Burl and Saya.
