"You go straight through between the sources of the North and the South Nahani," Marette had told him. "It is there you find the Sulphur Country, and beyond the Sulphur Country is the Valley of Silent Men."

At last he came to the edge of this country. He camped with the stink of it in his nostrils. The moon rose, and he saw that desolate world as through the fumes of a yellow smoke. With dawn he went on.

He passed through broad, low morasses out of which rose sulphurous fogs. Mile after mile he buried himself deeper in it, and it became more and more a dead country, a lost hell. There were berry bushes on which there grew no berries. There were forests and swamps, but without a living creature to inhabit them.

It was a country of water in which there were no fish, of air in which there were no birds, of plants without flowers--a reeking, stinking country still with the stillness of death. He began to turn yellow. His clothing, his canoe, his hands, face--everything turned yellow. He could not get the filthy taste of sulphur out of his mouth. Yet he kept on, straight west by the compass Gowen had given him at Hay River. Even this compass became yellow in his pocket. It was impossible for him to eat. Only twice that day did he drink from his flask of water.
