But there was no sign. Then the rockets bellowed, and the ship slowed its forward motion, hovered momentarily, and settled to solidity outside the framework of the grid. The grid was small, as Calhoun reasoned. But it reached interminably toward the sky.

The rockets cut off. Slender as the flames had been, they'd melted and bored thin drill-holes deep into the soil. Molten rock boiled and bubbled down below. But there seemed no other sound. There was no other motion. There was absolute stillness all around. But when Calhoun switched on the outside microphones a faint, sweet melange of high-pitched chirpings came from tiny creatures hidden under the vegetation of the mountainsides.

Calhoun put a blaster in his pocket and stood up.

"We'll see what it looks like outside," he said with a certain grimness. "I don't quite believe what the vision screens show."

Minutes later he stepped down to the ground from the Med Ship's exit port. The ship had landed perhaps a hundred feet from what once had been a wooden building. In it, ore from the mines was concentrated and the useless tailings carried away by a conveyer belt to make a monstrous pile of broken stone. But there was no longer a building.

Next to it there had been a structure containing an ore-crusher. The massive machinery could still be seen, but the structure was in fragments. Next to that, again, had been the shaft-head shelters of the mine. They also were shattered practically to matchsticks.

The look of the ground about the building sites was simply and purely impossible. It was a mass of hoofprints. Cattle by thousands and tens of thousands had trampled everything. Cattle had burst in the wooden sides of the buildings. Cattle had piled themselves up against the beams upholding roofs until the buildings collapsed.

Then cattle had gone plunging over the wrecked buildings until there was nothing left but indescribable chaos. Many, many cattle had died in the crush. There were heaps of dead beasts about the metal girders which were the foundation of the landing-grid. The air was tainted by the smell of carrion.

The settlement had been destroyed, positively by stampeded cattle in tens or hundreds of thousands charging blindly through and over and upon it. Senselessly, they'd trampled each other to horrible shapelessness. The mine shaft was not choked, because enormously strong timbers had fallen across and blocked it. But everything else was pure destruction.

Calhoun said evenly, "Clever! Very clever! You can't blame men when beasts stampede. We should accept the evidence that some monstrous herd, making its way through a mountain pass, somehow went crazy and bolted for the plains. This settlement got in the way and it was too bad for the settlement! Everything's explained, except the ship that went to Weald.
