"Maybe we could fix up a cart," said Adams, after thinking a moment.
"Out of what?" Cooper asked.
"Rollers, maybe. We could cut some and roll the logs up here."
"That would work on level ground," Hudson said. "It wouldn't work to roll a log uphill. It would get away from us. Someone might get killed."
"The logs would have to be longer than twelve feet, anyhow," Cooper put in. "You'd have to set them in a hole and that takes away some footage."
"Why not the tripod principle?" Hudson offered. "Fasten three logs at the top and raise them."
"That's a gin-pole, a primitive derrick. It'd still have to be longer than twelve feet. Fifteen, sixteen, maybe. And how are we going to hoist three sixteen-foot logs? We'd need a block and tackle."
"There's another thing," said Cooper. "Part of those logs might just be beyond the effective range of the force-field. Part of them would have to—have to, mind you—move in time and part couldn't. That would set up a stress...."
