It was not until Charlie was leaving that he gave Billy Louise a hint that his errand was not yet accomplished. She walked down with him to where his horse was tied and so gave him a chance to speak what was in his mind.
"You know, I hate to mention little worries before your mother," he said. "Those pathetic eyes of hers make me ashamed to bother her with a thing. But I am worried, Miss Louise. I came over to ask you if you've seen anything of four calves of ours. I know you ride a good deal, through the hills. They disappeared a week ago, and I can't find any trace of them. I've been looking all through the hills, but I can't locate them."
Billy Louise had not seen them, either, and she begged for particulars. "I don't see how they could get away from your Cove," she said, "unless your bars were down."
"The bars were all right. It was last Friday, I think. I'm not sure. They were in the little meadow above the house, you see. I was away that night, and Aunt Martha is a little hard of hearing. She wouldn't hear anything unless there were considerable noise. I came home the next forenoon—I was over to Seabeck's—and the bars were in place then. Aunt Martha had not been up the gorge, nor had anyone come to the ranch while I was gone. So you see, Miss Louise, here's a very pretty mystery!"
He laughed, but Billy Louise saw by his eyes that he did not laugh very deeply, and that he was really worried. "I must have made a mistake and bought mountain sheep instead of calves," he said and laughed again. "They couldn't have gone through those bars or over them; and I did have a spark of intelligence and looked along the river for tracks, you know. They had not been near the river, which has soft banks along there. They watered from the little creek that comes down the gorge. Miss Louise, do you have flying cattle in Idaho?"
"You think they were driven off, don't you?" Billy Louise asked a question with the words, and made a statement of it with her tone, which was a trick of hers.
Charlie Fox shook his head, but his eyes did not complete the denial. "Miss Louise, I'd work every other theory to death before I'd admit that possibility! I don't know all of my neighbors so very well, but I should hesitate a long, long time—"
"It needn't have been a neighbor. There are lots of strange men passing through the country. Did you look for tracks?"
"I—did not. I didn't want to admit that possibility. I decline to admit it now." The chin of Charlie Fox squared perceptibly, so that Billie Louise caught a faint resemblance to Marthy in his face. "I saw a man accused of a theft once," he said. "The evidence was—or seemed—absolutely unassailable. And afterward he was exonerated completely; it was just a horrible mistake. But he left school under a cloud. His life was ruined by the blunder. I'd have to know absolutely before I'd accuse anyone of stealing those calves, Miss Louise. I'd have to see them in a man's corral, with his brand on them—I believe that's the way it's done, out here—and even then—"
"Where have you looked?" There were reasons why this particular subject was painful to Billy Louise. "And are you sure they didn't get out of that pasture and wander on down the Cove, among all those willows? It's a perfect jungle, away down. Are you sure they aren't with the rest of the cattle? I don't see how they could leave the Cove, unless they were driven out." She caught a twinkle of amusement in his eyes and stopped short. Of course, a mere girl should not take it for granted that a man had failed to do all that might be done. And Billy Louise had a swift conviction that she would never think of talking like this to Ward. She flushed a little; and still, Charlie Fox was a tenderfoot. She was justified in asking those questions, and in her heart she knew it.
