"But he won't be. Drink makes him terribly sick. His stomach is very bad. That's why I always say it's stomach trouble. He ought to be taken care of to-night."

"He'll stay where he is and by himself," said Roger, grimly. "When I have a temper fit the next time, you can do the same by me. Lord, I'm glad Elsa is here! You lie quiet while I go milk."

When he had put the milk away he found that Charley had braided her hair but was still very white and shaken. Dick's shouts and curses floated in at the open door. Roger tied the little bundle of night things she had made up to the saddle and helped her to mount. She swayed dizzily and he put a strong, steadying arm about her. They made their way very slowly and Roger heaved a sigh of relief when they were finally beyond ear shot of poor Dick.

Elsa met them a short distance from the camp. "Hello, Charley," she said. "Felicia has just fallen asleep."

Roger nodded and at the living-tent door, helped Charley from the saddle. "Get this patient to sleep too, Elsa, if you can."

Elsa's eyes filled with tears as she looked at Charley. "You poor dear," she said, "come and let me take care of you."

One touch of a woman's sympathy, after her starved years, was too much for Charley. She burst into deep drawn sobs. Elsa, motioning Roger away, put her arm about the girl and led her into the tent.

Roger paced up and down in the sand for a while, listening to the low despairing sobs from the tent. Then he unsaddled Peter and put a huge bottle of water to heat. He had heard somewhere that women took great comfort in a cup of tea.

Roger passed rather a restless night. He had put Elsa's cot which she never had used, in the living tent so that Elsa could be close to her two patients, and himself put in the night in Gustav's shack which was built against the kitchen tent.

It was early July and the summer's heat was at its height. Three times between midnight and dawn Roger scratched a match and looked at the thermometer. It never registered below 118°. Even the night wind did not rise. The silence of the desert was complete as though torridity had overwhelmed every other aspect of nature. The stars were magnificent and for an hour or so, hoping to find the air outside cooler, Roger put a blanket on the work bench near the condenser and lay there, his face to the sky.
