"Well, if you insist," said Blake. He went around to the big armchair, across from Genevieve, and sat down wearily while explaining: "But the dam is a long way from being built. It's all on paper yet, and I've had to rely on the reports sent in by the field engineers."

A footman came in and set food and wine before Genevieve and Lord James. Blake went on, with quick-mounting enthusiasm, heedless of the coming and going of the soft-footed, unobtrusive servant.

"That's the only thing I'm afraid of. Would have liked to've gone over the ground myself first. But they had two surveys, and the field notes check fairly well. Barring mistakes in them, I've got the proposition worked out to a T. It's all done except some figuring of details that any good engineer could do. Just as well, for I'm about all in. Stiffest proposition I ever went up against."

He sank back into the depths of the big chair, with a sudden giving way of enthusiasm to fatigue. Lord James reached out his plate to him.

"You are pegged, old man," he said. "Have a sandwich."

"No," replied Blake. "I'm too played out to eat. Just want to rest."

Genevieve had been scrutinizing his face, and her deepening concern lent a note of sharpness to her reproach: "You're exhausted! You should not have come to-night!"

"Couldn't pass up a dance at your house, could I?" he smilingly rejoined. "Don't you worry about me. It's all right, long's I've got that whole damn irrigation system worked out."

"Ha! ha! old man!" chuckled Lord James. "That expresses it to a T, as you put it. But wouldn't it be better form to say, 'the whole irrigation dam system'?"

Blake smiled shamefacedly. "Did I make a break like—such as that?
'Scuse me, Miss Jenny. I'm sort of—I'm rather muddled to-night."
