"Oh, because. He simply wouldn't."

Harry kept silent, for she saw that Rob did not want to say any more about the matter. He seemed so greatly worried over Jones's absence that she restrained her impulse to tell him about Garnett and his sorrel horse.

On the third day Rob got up and announced that he was going to work.

"The first thing you know the cattle will be coming in round here to feed, and if I don't get that extra strand of wire round my fence before they get here, my critters will be up and off with the others."

Harry's heart thumped. "I might as well tell you, Bobs. The cow is gone already."

"Hey?" Rob turned quickly and stared at her. He looked pale and thin now that he was standing. "When did the cow get out?"

"I don't know—exactly. The day you got hurt, I guess."

"She may be in Boise by this time. Did the heifers go, too?"

"No, they are all here."

"Thank goodness! Well, I'll get right out after the other beast. I've heard Dan say a dry cow is a mean critter to keep tabs on. Put me up a lunch, will you, sis, while I'm saddling the pony?"
