The Courts of the Morning by John Buchan

Mr. Sylvester Perry in his Seeing Eyes asked a question which has often been asked by travellers, why the Gran Seco had no other route to the sea except by the three-hundred-mile journey south to the port of Olifa. Its city is not more than a hundred miles as the crow flies from the Pacific. The answer which Mr. Perry gives is that which he had from one of the transient managers of the struggling copper companies, that on the western side of the plateau the mountains simply cascade into the sea. Archie, who had asked himself the question, reached the same conclusion from a study of a map prepared long ago by the British Admiralty. The close lines of the hatching, though they must have been largely a matter of guesswork, showed that the sailors who had surveyed the coast had no doubt about its precipitous character, and up in the northern apex, where the great peak of Choharua overhung the ocean, the contours made the drop as sheer as the side of a house.

Oddly enough, about this time the same question occurred to the Gobernador. That northern angle had been left alone in his careful organisation of his province, for up there was neither wealth to be got nor men to get it. He called for the reports of those who had penetrated its recesses and all spoke with the same voice. The plateau rose in sharp tiers to meet the curve of the mountains, and these tiers were waterless desert. Higher up there were forests, which might some day be used for mine timber, and it might be possible to divert the streams from the snows, which now flowed seaward in sheer ravines, to the Gran Seco watershed. These things, however, were for the future. The Gobernador closed the reports and rolled up the maps, with a mental note that some day soon he must undertake a complete scientific survey of his province.
