impossibility that one could so self-disguise that he would negatively be detectable." He hesitated. "And these Energi," queried the beush, "are semi-telepathic or empathic?" "Affirmative," the assistant mumbled. "Then you have there a third reason," offered the beush. "Graces be given you, beush." The beush nodded in approval. "Continue, but negatively hesitate frequently or it will be necessary to discuss this subject post-present." His assistant trembled slightly. "Unequivocally affirmative. Beush, your memory relates that five periods ante-present, when there existed the Truce inter Energi, Terrans and ourselves, there was a certain period during which gifts of the three nucleus-planets were exchanged in friendship. The Terrans were self-contented to donate to the Energi an immense 'aquarium'—an 'aquarium' consisting of a partly transparent cell in which was placed a collection of Terran life-forms that breathed their oxygen from the dense atmosphere of Terran seas. But, as a warpspace message from the Terran Council indirectly proclaimed, the degenerate Terrans negatively possessed a ship of any Space type large or powerful enough to transport the 'aquarium' to Energa. Our ships being the largest of the Truce, we were petitioned by the Terrans to transport it. These events developed before the Terrans grew pestiferous to our cause. We obliged, but even our vastest ship was slow, because the physical power necessary to bring the weight of the cell through warpspace quickly was too great for the solitary four generators. It was imperative that the trip be on a longer trajectory arranged through norm-space. During the duration of the trip, feelings of suspicion arose inter Three Truce Races. As your memory also relates, the 'aquarium' was still in space when we found it necessary to obliterate the total race of Terrans. The message of the annihilation arrived in retard to the Energi, so Time permitted us to devise a contra-Energi intelligence plan, a necessity since it was realized that the Energi would be disturbed by our action contra-Terrans and would, without doubt, take action contra-ourselves. "Unknown to you, beush, or to the masses and highers, an insignificant pleasure craft was extracted from Terran Space and negatively consumed with a planet when
