Timkin held one carved stone in his hand for a moment, staring at its ancient writings. It was a triangular piece and seemed to have two sets of writing on it. To keep his mind from plunging into black despair Timkin tried to picture again the ancient civilization of the first moon. But a slight huddled figure sobbed aloud at the controls as the _Jetabout_ left the rings and aimed for Titan. At the Titan docks two days later Homer Timkin was calm and resigned. There was nothing he could do. No use to put in a complaint against Huck Larsoe, to the police. As Larsoe had said, it was one man's word against another's. With no witnesses the legal battle could only end with Larsoe the winner. Sighing, Timkin hired a rocket truck and piled the museum stuff aboard and drove to the center of Titan City. Here the Saturn Archeological Museum reared, stately and imposing on its marble pillars. Timkin drove to the service entrance and rang the bell. An elderly man answered and flashed a smile of greeting. "Well, Timkin again," he said. "Back with another load of relics from the rings? I take it you didn't hit any bonanza then, eh?" "Well, I--" Timkin stopped. No need to go into his story, and broadcast his shame and misery to the universe. "No, Professor Blick. No bonanza. But I've got a load of stuff for you to look over for your museum." Professor Blick, adjusting his thick glasses, came out and looked over each item as Timkin took it off the truck. "Our prices are still standard, Timkin," he said. "Two SS-dollars for a specimen of coal. Three for fossil bones. Five for bits of machinery. And ten for the carved stones." "Why," asked Timkin curiously, "do you pay more for the stones than anything?" "Because if they could speak they would tell us far more about the ancient civilization of the first moon, than any of the other items. We have a sizeable collection now. We can't translate the writing yet. But some day we're going to find the Rosetta Stone that will give us the clue and open up the whole vast story." "Rosetta Stone?" Timkin was puzzled. The professor went on conversationally. "Yes. You see, back on earth many centuries ago, the archeologists of that time also found carved writings--the ancient records of the Egyptians. And they too were a riddle. "But one day a stone was found with not only Egyptian heiroglyphics on it but _another language_! The text on this stone had been written in Egyptian and then copied in the other language. And that second language--ancient Greek--was _known_! So this enabled all the Egyptian writing to be translated and...." The professor's voice stopped, with a queer gurgle. Timkin stared. He had just handed him the triangular stone which had been among Larsoe's "gifts." "_Timkin!_" screeched the professor. "This is _it_! This stone has _two_ sets of writing on it. One is the unknown script of the first moon. And the other is--oh, thank the stars!--it's early Rhean, _which is a language we know_!"
