That was about what I'd thought. Tom knew more about lift-and-drive engines than I'd ever learn, and I was willing to take his opinion as confirmation of my own. "Tom, take a look at this mess," I said. "See if you can help us with it." He came over, looked at what we were working on, and said, "You need a magnifier for this. Wait till I see something." Then he went over to one of the lockers, rummaged in it, and found a pair of binoculars. He came over to us again, sat down, and began to take them apart. As soon as he had the two big objective lenses out, we had two fairly good magnifying glasses. That was a big help, but being able to see what had to be done was one thing, and having tools to do it was another. So he found a sewing kit and a piece of emery stone, and started making little screwdrivers out of needles. After a while, Abe Clifford and Piet Dumont and the other man returned and made a beeline for the heater and the coffeepot. After Abe was warmed a little, he said: "There's a little waterfall about half a mile up. It isn't too hard to get up over it, and above, the ground levels off into a big bowl-shaped depression that looks as if it had been a lake bottom, once. The wind isn't so bad up there, and this whole lake bottom or whatever it is is grown up with trees. It would be a good place to make a camp, if it wasn't so far from the boat." "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. The waterfall above the boat was higher than the one below, but not quite so hard to climb, especially as we had the two lifters to help us. The worst difficulty, and the worst danger, was from the wind.
