It was two days before Gahan had crossed the plain and reached the summit of the hills from which he hoped to see his own country, only to meet at last with disappointment. Before him stretched another plain, of even greater proportions than that he had but just crossed, and beyond this other hills. In one material respect this plain differed from that behind him in that it was dotted with occasional isolated hills. Convinced, however, that Gathol lay somewhere in the direction of his search he descended into the valley and bent his steps toward the northwest. For weeks Gahan of Gathol crossed valleys and hills in search of some familiar landmark that might point his way toward his native land, but the summit of each succeeding ridge revealed but another unfamiliar view. He saw few animals and no men, until he finally came to the belief that he had fallen upon that fabled area of ancient Barsoom which lay under the curse of her olden gods--the once rich and fertile country whose people in their pride and arrogance had denied the deities, and whose punishment had been extermination. And then, one day, he scaled low hills and looked into an inhabited valley--a valley of trees and cultivated fields and plots of ground enclosed by stone walls surrounding strange towers. He saw people working in the fields, but he did not rush down to greet them. First he must know more of them and whether they might be assumed to be friends or enemies. Hidden by concealing shrubbery he crawled to a vantage point upon a hill that projected further into the valley, and here he lay upon his belly watching the workers closest to him. They were still quite a distance from him and he could not be quite sure of them, but there was something verging upon the unnatural about them. Their heads seemed out of proportion to their bodies--too large. For a long time he lay watching them and ever more forcibly it was borne in upon his consciousness that they were not as he, and that it would be rash to trust himself among them. Presently he saw a couple appear from the nearest enclosure and slowly approach those who were working nearest to the hill where he lay in hiding. Immediately he was aware that one of these differed from all the others. Even at the greater distance he noted that the head was smaller and as they approached, he was confident that the harness of one of them was not as the harness of its companion or of that of any of those who tilled the fields.
