"Boss," he said, "I chin a lot to keep me cheered up while I finish Iron Skull's job. I wish he could have stayed to finish it. Of course he helped on the Makon but he never had as good a job as he's got here. Ain't it hell when a man goes without a trace of anything living behind him! A man ought to have kids even if he don't have ideas. I often told Iron Skull that. But he said he couldn't ask a woman to live the way he had to. I always told him a woman would stand anything if you loved her enough."

Jim nodded. Iron Skull's life in many ways seemed a personal reproach to Jim for his own way of living.

The work at the abutments absorbed Jim until late afternoon; absorbed him and cheered him. About five o'clock he started off to call on Pen, and tell her about the Secretary's letter. He found her plodding up the road toward the tent house with a pile of groceries in her arms.

"I missed the regular delivery," she replied to his protests as he took the packages from her, "and I love to go down to the store, shopping. It's like a glorified cross-roads emporium. All the hombres and their wives and the 'rough-necks' and their wives and the Indians. Why it's better than a bazaar!"

Jim laughed. "Pen, you are a good mixer. You ought to have my job. You'd make more of it than I do."

"That reminds me," said Pen. "Jim, that man Fleckenstein is going to run for United States Senator. He's going to promise the ranchers that he'll get the government to remit the building charges on the dam. Will that hurt you?"

"Where did you hear this?" asked Jim.

"Fleckenstein and Oscar came up this morning and they talked it over with Oscar. Sara was guarded in what he said before me, but I believe he's going to get campaign money back East. Why should he, Jim?"

She eyed Jim anxiously. There was hardly a moment of the day that the thought of the responsibility that Iron Skull had placed on her shoulders was not with her. But she was resolved to say nothing to Jim until she had a vital suggestion to make to him.

Jim looked at the shimmering lavenders and grays of the desert. It had come. A frank step toward repudiation. A blow at the fundamental idea of the Service. That was to be the next move of the Big Enemy. And what had Sara to do with it? All thought of the Secretary's letter left Jim. He must see Sara. But Penelope must not be unduly worried. He turned to her with his flashing smile.
