"How hard would it be to cut wood up there and bring it down?" Joe asked, going on to explain what he had in mind.

"Why, easy. I don't think it would be nearly as hard as the place Ramón found."

"Neither do I," the mate agreed. "Climbing up that waterfall down the stream with a half tree trunk would be a lot harder than dropping one over beside the one above." He began zipping up his parka. "Let's get the cutter and the lifters and go up now."

"Wait till I warm up a little, and I'll go with you," Abe said.

Then he came over to where Cesário and Tom and I were working, to see what we were doing. He chucked appreciatively at the midget screwdrivers and things Tom was making.

"I'll take that back, Ramón," he said. "I can do a lot more good right here. Have you taken any of the radio navigational equipment apart, yet?" he asked us.

We hadn't. We didn't know anything about it.

"Well, I think we can get some stuff out of the astrocompass that can be used. Let me in here, will you?"

I got up. "You take over for me," I said. "I'll go on the wood-chopping detail."

Tom wanted to go, too; Abe told him to keep on with his toolmaking. Piet Dumont said he'd guide us, and Glenn Murell said he'd go along. There was some swapping around of clothes and we gathered up the two lifters and the sonocutter and a floodlight and started upstream.
