* * * * * Aft, in the crew's quarters, a gong sounded sharply: the signal for changing watches, and the beginning of a sleep period. I glanced at the remote control dials that glowed behind their glass panel on one side of my room. From the registered attraction of Jaron, at our present speed, we should be passing her within, according to Earth time, about two hours. That meant that their outer patrols might be seeking our business, and I touched Barry's attention button, and spoke into the microphone beside my bunk. "Mr. Barry? I am turning in for a little sleep. Before you turn over the watch to Eitel, will you see that the nose rays are set for the Special Patrol code signal for this enar. We shall be close to Jaron shortly." "Yes, sir! Any other orders?" "No. Keep her on her present course. I shall take the watch from Mr. Eitel." Since there have been changes since those days, and will undoubtedly be others in the future, it might be well to make clear, in a document such is this, that at this period, all ships of the Special Patrol Service identified themselves by means of invisible rays flashed in certain sequences, from the two nose, or forward, projectors. These code signals were changed every enar, a period of time arbitrarily set by the Council; about eighteen days, as time is measured on the Earth, and divided into ten periods, as at present, known as enarens. These were further divided into enaros, thus giving us a time-reckoning system for use in space, corresponding roughly to the months, days and hours of the Earth. I retired, but not to sleep. Sleep would not come. I knew, of course, that if curious outer patrol ships from Jaron did investigate us, they would be able to detect our invisible ray code signal, and thus satisfy themselves that we were on the Council's business. There would be no difficulty on that score. But what I should do after landing upon the rebellious sphere, I had not the slightest idea. * * * * * "Be stern, indifferent to their threats," Kellen, had counseled me, "but do everything within your power to make them see the folly of their attitude. Do not threaten them, for they are a surly people and you might precipitate matters. Swallow your pride if you must; remember that yours is a gigantic responsibility, and upon the information you bring us may depend the salvation of millions. I am convinced that they are not--you have a word in your language that fits exactly. Not pretending ... what is the word?" "Bluffing?" I had supplied in English, smiling. "Right! Bluffing. It is a very descriptive word. I am sure they are not bluffing." I was sure of it also. They knew the power of the Alliance; they had been made to feel it more than once. A bluff would have been a foolish thing, and these people were not fools. In some lines of research they were extraordinarily brilliant.
