The _Lunar Star_ got through safely. It was turned aside by a last minute warning from the Pluto Lamp beacon. This impressed the importance of the Lamp in the minds of the authorities, as is attested to by history, for it was in service well over one hundred years after Salvor-Jones's ordeal. In Selena City there is a small monument, equally dedicated to the two heroes, Salvor-Jones and Smith. For the professor declared that Smith had been as much responsible for the success of the Lamp as he, himself. Hadn't he saved the day, there at the very last? As for Knucklebone Smith, his frozen body still lies in simple state on Pluto. There is a faint, fixed smile on his face; or presumably there is, for Salvor-Jones attests that it was there that night. And it can hardly have escaped him now. For it was just as Knucklebone had always said. Every man is good for something. Even if it is only to be used for a lever.
