At ten o'clock Rob had not yet come. What could be keeping him? Had the pony stumbled and thrown him? Could he have had a sunstroke? Suppose he had fainted out there alone—without water——

Resolutely Harry turned from such thoughts. He had probably lost his way and would get home very late. She would be foolish to sit up for him.

She undressed very slowly, listening, hoping to hear the sound of the pony's hoofs; but soon she grew too sleepy to listen for them.

When she awoke it was broad daylight; the clock had stopped and Rob had not come. She went to the doorway and looked all round. The same silence, the same blaze of sunlight, the same solitude. Was it really another day? In the unbroken quiet everything seemed at a standstill. She did the chores and worked in the garden; but all the time she listened. And Rob did not come.

The day passed, and another night. She slept fitfully. Several times she thought she heard the beat of hoofs, and trembling with hope, hurried out to look. When the third day passed without bringing Rob, Harry knew that something had happened to him.

She sat beside the table in the evening with her head in her hand. She wished that it were not too late to go over and talk with Mrs. Robinson. She felt the instinct to lay her troubles upon some one else. Then she bethought herself and crushed down the impulse. The Robinsons were all busy with the haying. She had no right to call upon them for help, and moreover, she would be ashamed to do it. She must help herself. She would drive the twenty miles to Soldier, and send some one out to look for her brother.

When her alarm clock rang the next morning she hopped resolutely out into the chilly dawn, dressed, and got her breakfast.

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.
