At his sudden enthusiasm the lecturer's face took on what they had come to recognize as a very dour look. "That series of transformations has no interest for us," he said. "I merely indicated its existence to show one of the possibilities which should be avoided. Over here you see the direction in which we wish to go." "But you never saw anything with properties like that!" Carmen protested. "It goes through an incredible series of at least three crystalline-liquid phase changes with an increase in pressure alone. But with proper control of heat it can be kept in the crystalline phase regardless of pressure. It is closely related to a drug series with anesthetic properties, and is almost sure to be valuable in--" The Ryke lecturer cut him off sharply. "I have explained," he said, "the direction of transformation in which we are interested. Your concern is not with anything beyond the boundaries which our study has proven to be the direct path of research and study." "Then I should abandon research on this series of chemicals?" Carmen asked with a show of outward meekness. The Ryke nodded with pleasure at Carmen's submissiveness. "That is it precisely. We have been over this ground long ago. We know where the areas of profitable study lie. You will be told what to observe and what to ignore. How could you ever hope to make progress if you stopped to examine every alternate probability and possibility that appeared to you?" He shook his head vigorously and his plume vibrated with emotion. "You must have a plan," he continued. "A goal. Study of the Universe cannot proceed in any random, erratic fashion. You must know what you want and then find out where to look for it." Carmen sat down slowly. Hockley was sure the Ryke did not notice the tense bulge of the chemist's jaw muscles. Perhaps he would not have understood the significance if he had noticed. * * * * * Hockley was a trifle late in getting to the dining room at lunch time that day. By the time he did so the place was like a beehive. He was almost repelled by the furor of conversation circulating in the room as he entered. He passed through slowly, searching for a table of his own. He paused a moment behind Dr. Carmen, who was declaiming in no mild terms his opinions of a system that would pre-select those areas of research which were to be entered and those which were not. He smiled a little as he caught the eye of one of the dozen chemists seated at the table, listening. Moving on, he observed that Silvers had also cornered a half dozen or so of his colleagues in his own field and was in earnest conversation with them--in a considerably more restrained manner, however, than he had used the previous evening with Hockley, or than Carmen was using at the present time. The entire room was abuzz with similar groups.
