"Agreed," said he.

There was a time for slaves, and a time for matters of importance.

"Yet there is little to report," said he, "in the affairs of worlds."

"The Kurii are quiet," I said.

"Yes," said he.

"Beware of a silent enemy," I smiled.

"Of course," said Samos.

"It is unusual that you should invite me to your house," I said, "to inform me that you have nothing to report."

"Do you think you are the only one upon Gor who labors occasionally in the cause of Priest-Kings?" asked Samos.

"I suppose not," I said. "Why?" I asked. I did not understand the question.

"How little we know of our world," sighed Samos.

"I do not understand," I said.

"Tell me what you know of the Cartius," he said.

"It is an important subequatorial waterway," I said. "It flows west by northwest, entering the rain forests and emptying into Lake Ushindi, which lake is drained by the Kamba and the Nyoka rivers. The Kamba flows directly into Thassa. The Nyoka flows into Schendi harbor, which is the harbor of the port of Schendi, and moves thence to Thassa." Schendi was an equatorial free port, well known on Gor. It is also the home port of the League of Black Slavers.

"It was, at one time, conjectured," said Samos, "that the Cartius proper was a tributary of the Vosk."

"I had been taught that," I said.

"We now know that the Thassa Cartius and the subequatorial Cartius are not the same river."

"It had been thought, and shown on many maps," I said, "that the subequatorial Cartius not only flowed into Lake Ushindi, but emerged northward, traversing the sloping western flatlands to join the Vosk at Turmus." Turmus was the last major river port on the Vosk before the almost impassable marshes of the delta.

"Calculations performed by the black geographer, Ramani, of the island of Anango, suggested that given the elevations involved the two rivers could not be the same.
