Dan got out a map and noted a long, fairly straight road from one of the cities, near which he had a mataform transceiver, to another distant city. From this distant city, a winding river curled away to a city even more distant. That night, Dan intended to make use of road and river alike. But right now, he spent an hour or so moving his goods to a place further away from the landing; then he partly reassembled the boat, and cat-napped till evening. He was awoken at frequent intervals by sudden drops of men and more of the tiger-like animals, at each of the four places where they had been before. Each time there was sudden activity at one of these places, a little alarm buzzed in Dan's ear, and he slid on the helmet to watch a renewed search of the ground. He had the impression that someone had reported nothing was to be found, and that this word had been passed along to someone who had said there _must_ be something there, and it had better be found or else. The search this time was much more careful. But it was not till the last place was searched that one of them came very close to the spy unit, and reached out toward it. Dan regretfully slid back a protective cover at the lower edge of the helmet and pressed a button underneath. There was a dazzling flash, and then the scene was gone. Dan would much rather have kept them thinking that maybe there was nothing to look for after all. But he could tell from their numbers and zeal that he was not likely to have very much his own way on this planet. * * * * * That night, Dan sent a glider under power down the long road to the distant city. The glider was low enough to avoid the usual detectors, but happily free of the need to dodge an endless succession of tree trunks. The river served much the same purpose, so that well before dawn, Dan had mataform transceivers planted near each of the two new cities, and also at a place right at the edge of the river. From this spot, Dan threw out into the river a heavily weighted mataform transceiver. He returned to the partly assembled boat and methodically put it together again. This time, however, he fitted sections together differently and left the heavy engine out entirely. He put his arms around one end of the thing he had put together and mentally said a keyword. The river water rushed coldly around him, gritty with silt sweeping along the bottom. There was a _chug_ in his ears as the water triggered off the grab anchors around the rim of the shelter. Dan said another key word and he was inside. He snapped on a light and looked carefully around, but found no sign of a leak. He transferred the rest of his goods, checked to see that the selective membrane panel was keeping the oxygen at the right level inside, then lay down to catch up on sleep. The following day, he took three of his small transceivers, and went by the mataform to a place outside the nearest city.
