"Then let us begin at once. I would like to see the thing accomplished," Robur urged.

Croft nodded and briefly described what was required.

"There is a place where the doors of metal and the bodies of the chariots and carriage are molded," Robur said. "Metal is melted and worked into shape, according to designs."

Croft had felt assured that some such industry existed from the molded doors and the type of the other metalwork he had seen. "Take me there, O Robur of Aphur," he said.

Robur laughed. He was an exceedingly companionable man. "Call me not by so lengthy a title," he exclaimed. "I am drawn to you, Jasor. Let us forget questions of caste or rank between ourselves. Speak to me as Rob."

"Gladly will I call you so," said Croft, his heart warming to this proffered friendship of Aphur's heir. "And let us pledge ourselves now to work for the welfare of our nation until it is assured." He thrust out a hand.

Robur's eyes lighted as they held Croft's palm. "This is a day of wonder for all Tamarizia," he said, and turned the gnuppas southward along the river road.

In the end he brought them to a stand before an enormous building, wherein Croft found the flares of fires, and men, well-nigh naked, at work in their glare. Robur led him to the captain in charge of the place, and made him acquainted with Croft's needs. Inside an hour Croft was superintending the makings of certain wooden patterns, to be molded and cast in tempered copper, while Robur looked on, all eyes.

And his eyes were glinting as they left the Palosian foundry and drove toward the royal depots of wines, after Croft had given certain of the metal-workers the designs for a huge copper retort to be made at once.

At the depots, where Croft found unlimited supplies of wine, stored in skin bottles of tabur hide, Jason ordered the building of a brick furnace for the retort when it was done, giving the dimensions and plans of construction to masons hurriedly called. That task arranged for, Robur drove him back to the palace, and led him straight to his own private suite.
