Harker handed him the rope. "Get around the other side of the canyon. Clear across, see?" He helped McLaren on with his pack. "Stand by with the rope to pull me up. And keep to the bare rocks." McLaren went off. He limped badly, his face twisted with pain. Harker swore. The cloud was so close that now he could see the millions of tiny seeds floating on their silken fibres, thistledown guided by the minds of the flower-people in the valley. He shrugged into his pack straps and began winding bandages and tufts of dead grass around the bone tip of a recovered spear. The edge of the cloud was almost on him when he got a spark into the improvised torch and sprang down onto the heap of dead flower-things in the pit. He sank and floundered on the treacherous surface, struggling across it while he applied the torch. The dry, withered substance caught. He raced the flames to the far wall and glanced back. The dying creatures had not stirred, even when the fire engulfed them. Overhead, the edges of the seed-cloud flared and crisped. It moved on blindly over the fire. There was a pale flash of light and the cloud vanished in a puff of smoke. "Rory!" Harker yelled. "Rory!" * * * * * For a long minute he stood there, coughing, strangling in thick smoke, feeling the rushing heat crisp his skin. Then, when it was almost too late, McLaren's sweating face appeared above him and the rope snaked down. Tongues of flame flicked his backside angrily as he ran monkey-fashion up the wall. They got away from there, higher on the rocky ground, slashing occasionally with their knives at brush and creepers they could not avoid. McLaren shuddered. "It's impossible," he said. "How do they do it?" "They're blood cousins. Or should I say sap. Anyhow, I suppose it's like radio control--a matter of transmitting the right frequencies. Here, take it easy a minute." McLaren sank down gratefully. Blood was seeping through the tight bandages where Harker had incised his wound. Harker looked back into the valley. The flower people were spread out in a long crescent, their bright multi-colored heads clear against the green plain. Harker guessed that they would be guarding the pass. He guessed that they had known what was going on in his mind as well as Button had. New form of communism, one mind for all and all for one mind. He could see that even without McLaren's disability they couldn't make it to the pass. Not a mouse could have made it. He wondered how soon the next seed-cloud would come. "What are we going to do, Matt? Is there any way...." McLaren wasn't thinking about himself. He was looking at the valley like Lucifer yearning at Paradise, and he was thinking of Viki. Not just Viki alone, but Viki as a symbol of thirty-eight hundred wanderers on the face of Venus.
