Then, one day, a lone visitor--a strange, two-legged creature composed mostly of water--landed on Mars..._ BY VERNON L. MC CAIN The dehydration of the planet had taken centuries in all. The Rell had still been a great race when the process started. Construction of the canals was a prodigious feat but not a truly remarkable one. But what use are even canals when there is nothing to fill them? What cosmic influences might have caused the disaster baffled even the group-mind of the Rell. Through the eons the atmosphere had drifted into space; and with it went the life-giving moisture. Originally a liquid paradise, the planet was now a dry, hostile husk. The large groups of Rell had been the first to suffer. But in time even the tiny villages containing mere quadrillions of the submicroscopic entities had found too little moisture left to satisfy their thirst and the journey ever southward toward the pole had commenced. The new life was bitter and difficult and as their resources were depleted so also did their numbers diminish. [Illustration] Huddled at their last retreat the Rell watched the ever smaller ice cap annually diminish and lived with the knowledge they faced extinction. A mere thousand years more would see even this trifling remainder gone. Oh, you might say there was hope ... of a sort. There might be Rell in the northern hemisphere. The canals girdled the globe and a similar ice cap could well exist at the opposite pole. Rell perhaps survived there also. But this was scant comfort. The fate of the Rell in the South was sealed. What hope of any brighter future for those in the North? And if they survived a few hundred thousand years longer ... or if they had perished a similar period earlier, what actual difference did it make? There was no one more aware of this gloomy future than Raeillo/ee13.
