It was remarkable that Burl was able to think of his feelings instead of his sensations. His tribesmen were closer to it than equally primitive folk had been back on Earth, but they did not often engage in thought. Their waking lives were filled with nerve-racked physical responses to physical phenomena. They were hungry and they saw or smelled food: they were alive and they perceived the presence of death. In the one case they moved toward the sensory stimulus of food; in the other they fled from the detected stimulus of danger. They responded immediately to the world about them. Burl, for the first significant time in his life, had responded to inner feelings. He had resolved conflicting emotions by devising a purpose that would end their conflict. He determined to do something because he wanted to and not because he had to. It was the most important event upon the planet in generations. With the directness of a child, or a savage, Burl moved to carry out his purpose. The fish still slung about his neck scraped against his chest. Fingering it tentatively, he got himself thoroughly greasy in the process, but could not eat. Although he was not hungry now, perhaps Saya was. He would give it to her. He imagined her eager delight, the image reinforcing his resolve. He had come to this far place down the river flowing sluggishly past this riotously-colored bank. To return to the tribe he would go back up that bank, staying close to the stream. He was remarkably exultant as he forced a way through the awkward aisles of the mushroom-forest, but his eyes and ears were still open for any possible danger. Several times he heard the omnipresent clicking of ants scavenging in the mushroom-glades, but they could be ignored. At best they were short-sighted. If he dropped his fish, they would become absorbed in it. There was only one kind of ant he needed to fear--the army ant, which sometimes traveled in hordes of millions, eating everything in their path. But there was nothing of the sort here. The mushroom forest came to an end. A cheerful grasshopper munched delicately at some dainty it had found--the barrel-sized young shoot of a cabbage-plant. Its hind legs were bunched beneath it in perpetual readiness for flight. A monster wasp appeared a hundred feet overhead, checked in its flight, and plunged upon the luckless banqueter.
