"We believe that Lyrane IX was visited by beings having sufficient power of mind to leave no traces whatever as to who they were or where they came from. We also believe that there was no surgery, but an infinitely finer kind of work--an indetectable subconscious compulsion--done on the minds of the Black Lensmen and others who came into physical contact with the Boskonians. These opinions are based upon experiences which we five have had and upon deductions we have made. If we are right, Lyrane is actually, as well as apparently, a dead end and should be abandoned. Furthermore, we believe that the Black Lensmen have not been and cannot become important." The Co-ordinator was surprised, but after Kit and his sisters had detailed their findings and their deductions, he turned to the Rigellian. "What next, then, Tregonsee?" "After Lyrane IX, it seems to me that the two most promising subjects are those entities who think upon such a high band, and the phenomenon which has been called 'The Hell Hole in Space.' Of the two, I preferred the first until Camilla's researches showed that the available data could not be reconciled with the postulate that the life-forms of her reconstruction were identical with those reported to you as Co-ordinator. This data, however, was scanty and casual. While we are here, therefore, I suggest that we review this matter much more carefully, in the hope that additional information will enable us to come to a definite conclusion, one way or the other. Since it was her research, Camilla will lead." * * * * * "First, a question," Camilla began. "Imagine a sun so variable that it periodically covers practically the entire possible range. It has a planet whose atmosphere, liquid, and distance are such that its surface temperature varies from approximately two hundred degrees Centigrade in midsummer to about five degrees absolute in midwinter. In the spring its surface is almost completely submerged. There are terrible winds and storms in the spring, summer, and fall; but the fall storms are the worst. Has anyone here ever heard of such a planet having an intelligent life-form able to maintain a continuing existence through such varied environments by radical changes in its physical body?" A silence ensued, which Nadreck finally broke. "I know of two such planets. Near Palain there is an extremely variable sun, two of whose planets support life. All of the higher life-forms, the highest of which are quite intelligent, undergo regular and radical changes, not only of form, but of organization."
