Carson's eyes went swiftly to Bud Lee's. In Carson's mind there was a quick suspicion: The strain of life on the ranch was proving too much for a girl, after all.

Judith, reading his thought, turned up her nose at him and, seeking to keep her feet hidden as she walked by sagging a little at the knees, went to the door. Turning there, she saw in Lee's eyes the hint of a smile, a very approving, admiring smile.

"Impudent!" she cried within herself. Looking very tiny, her knees bent so that her robe might sweep the floor, she continued with all possible dignity to the hallway. Once there, she ran for her room, her gown fluttering widely about her. In her room, though she dressed hurriedly, she still took time for a long and critical examination of two rows of little pink toes.

"Just the same," she said to the flushed Judith in the mirror, "they are very nice feet—Bud Lee, I'd just like to make you squirm one of these days. You're altogether too—too—oh, scat, Judy. What's the matter with you?"

In less than half an hour Doc Tripp, showing every sign of a hurried toilet, rode into the courtyard. He came swiftly into the office, bag in hand. Judith, waiting impatiently for him, lost no words in telling him her suspicions. And Doc Tripp, hearing her out, swore softly and fluently, briefly asking her pardon when he had done.

"I'm a jackass," he said fervently. "I always knew I was a fool, but I didn't know that I was an idiot! Why, Judy, those damned pigeons have been sailing all over the ranch, billing and cooing and picking up and toting cholera germs. Any fool can see it now. I might have known something was up when Trevors bought the infernal things. It's as simple as one, two, three. Now this other jasper, pretending to look for a job, brings on some more of them, so that the disease will spread the faster. Let me get my two hands on him, Judith. For the love of God, lead me to him."

But, instead, she led him to the dozen white pigeons which Carson brought in.

Tripp, all business again, improvised his laboratory, washed the pigeons' feet, made his test, with never another curse to tell of his progress. Judith left him and went into the courtyard, where, in a moment, Carson came to her.

"You better tell me what's up," he said sharply. "I know something is. That new guy that just come in is darned hard to keep. Just as quick as I grab a shotgun an' go to shooting pigeons he moseys out to the corrals an' starts saddling his horse."

"Don't let him go!"
