"Right!" said Lockley at last. "I'll check with Vale and on out of the park, and then we'll put it all together and wrap it up and take it home."

Sattell agreed. Lockley, rather absurdly, felt uncomfortable because he was going to have to talk to Vale. He had nothing against the man, but Vale was, in a way, his rival although Jill didn't know of his folly and Vale could hardly guess it.

He signed off to Sattell and swung the base line instrument to make a similar check with Vale. It was now ten minutes after nine. He aligned the instrument accurately, flipped the switch, and began to say as patiently as before, "Calling Vale. Calling Vale. Lockley calling Vale. Over."

He turned the control for reception. Vale's voice came instantly, scratchy and hoarse and frantic.

"Lockley! Listen to me! There's no time to tell me anything. I've got to tell you. Something came down out of the sky here nearly an hour ago. It landed in Boulder Lake, and at the last instant there was a terrific explosion and a monstrous wave swept up the shores of the lake. The thing that came down vanished under water. I saw it, Lockley!"

Lockley blinked. "Wha-a-at?"

"A thing came down out of the sky!" panted Vale. "It landed in the lake with a terrific explosion. It went under. Then it came up to the surface minutes later. It floated. It stuck things up and out of itself, pipes or wires. Then it moved around the lake and came in to the shore. A thing like a hatch opened and ... creatures got out of it. Not men!"

Lockley blinked again. "Look here—"

"Dammit, listen!" said Vale shrilly, "I'm telling you what I've seen. Things out of the sky. Creatures that aren't men. They landed and set up something on the shore. I don't know what it is. Do you understand? The thing is down there in the lake now. Floating. I can see it!"

Lockley swallowed. He couldn't believe this immediately. He knew nothing of radar reports or the seismograph record. He'd seen a barely balanced rock roll down the mountainside below him, and he'd heard a growling bass rumble behind the horizon, but things like that didn't add up to a conclusion like this! His first conviction was that Vale was out of his head.
