No one who is used to handling horses can understand Harry's feelings as she lifted the heavy set of harness from the peg beside Rock's stall and dragged it over his back. She had watched her brother often as he harnessed the team, and remembered something about the way he had done it; but it was mostly by luck that she got the various straps into their proper places. Her heart beat nervously as she led the horses out of the corral and backed them up before the wagon. Suppose they should run away? But Rock and Rye were a steady team, and stood serenely while Harry fastened the tugs. It was only half-past seven o'clock when she left the ranch, but she felt as if she had already done a day's work. She drove slowly at first, afraid that something would go wrong with the harness or that the horses would run away; but after the first few miles her spirits rose above her worries, and by the time she reached the Robinsons' ranch she was enjoying every moment of the ride. As she passed the house Vashti burst from the door and, waving a letter, ran toward her. "You want me to post this?" Harry asked, as she pulled up the horses. "Oh, no! It's for you," Vashti said, and thrust the envelope into Harry's hand. "Hank Miller fetched it out from Hailey yestiddy." "It's from Rob!" exclaimed Harry, and laughed with relief. Then, as her eyes flew down the sheet, her face clouded. The note read: DEAR HARRY. I'm in the jug at Hailey. It's about those horses of Jones's. Bring that paper he gave me. It's a bill of sale. I stuck it up behind the clock on the shelf, next to the coffee grinder. Come over with it as soon as you can. Get one of the R. boys to tend the stock while you're gone. ROB. "'Tain't bad news, is it?" Vashti's voice broke Harry's dismayed silence. "What? O Vashti, I must go to Hailey this minute. Can one of the boys tend the stock while I'm gone? Thanks ever so much. Which is the shortest way to Hailey? I suppose I must go by way of Soldier?" "No. Cross the river by the lower bridge and then strike for the pike about Willow Creek." Vashti pointed eastward. "You'd ought to make it before dark if you hustle." "How far is it? I don't know the road at all." "You don't! Say! You want to watch for the big pillar butte. It's on the right where the road splits to go over the mountains. And say! Keep to the east whenever you hit a fork. Where are you going?" she added, as Harry turned the team homeward. "I've got to go back and get a paper Rob wants." "Say!" Vashti called after her suddenly. "Let me go for you. I can ride over there on Geezer and back while you're gettin' turned round." Without waiting for an answer the little girl ran to the corral, led out the pony, flung a saddle over his back, shoved the bridle over his ears, and came back to Harry on the run.
