This took time; and it was two years after the acquisition of Prairie Southern that York, a trifle grayer and a shade more dictatorial than before, was one morning handed a card by his secretary. He frowned at it, for the name was strange.

"Who's this Casey Dunne, and what does he want?"

Dunne, it appeared, wished to see him in connection with the Coldstream irrigation project, then well under way. He owned property in that vicinity; he also represented certain other ranchers.

"Lawyer?" snapped York. The secretary thought not. "Show him in."

When Dunne entered York did not immediately look up from his papers. This was for general effect. When he did look he became conscious that even as he was measuring so was he being measured.

Casey Dunne carried an atmosphere of outdoors. From the deep tan of his neck, against which the white of his collar lay in startling contrast, to the slender, sinewy brown hands, he bore token of wind and sun and activity in the open. His clothes were new, excellent in fit and material; but, though he did not wear them awkwardly, one gathered the impression that he was accustomed to easier, more informal garments. His manner was entirely self-confident, and betrayed neither awe nor embarrassment. Which gave York an unfavourable impression to start with.

"Take a chair, Mr. Dunne," he said. "I can give you five minutes or ten. Not more. What can I do for you?"

"I may have to ask you to stretch that time limit a little," said Dunne, smiling as if York were an old friend. "Let me start at the beginning, and then I won't have to go back. I live down on the Coldstream, on the line of the old Prairie Southern, which you acquired a couple of years ago. With it you got their land grant. Your land department, after looking the Coldstream blocks over, decided to irrigate and sell these lands; and they undertook a main ditch and a system of ditches, and they are selling the lands at the present time."

"I know all this," said York impatiently. "Carrol runs our land department, and he deals with these matters. He's the man you want to see."

"He referred me to you," said Dunne. "I know this is ancient history, but I'm cleaning up as I go along. You will get your water for these lands from the Coldstream. I and others own property there, and we get our water from the river below your intake. Are you aware that your ditch system is capable of carrying, and that the lands you are selling with a guarantee of an adequate water supply will require, almost the entire normal flow of the Coldstream?"
