“Oh, I see!” David Linton laughed. “It's—a distance handicap—the ponies all start at the same moment, but from different points along the track.”

“Yes, that must be it,” Norah said. “Jim's away over near the timber with a little rat of a pony, and Bob is shepherding another fifty yards behind him, while Wally is quite near here with that big pony of the blacksmith's that has won ever so many races. She'll have a lot of ground to make up. But why must each one be shepherded, Dad?”

“Human nature,” said David Linton, smiling. “These youngsters who are riding would sneak a yard or two if they weren't closely watched, and they would never start fair; the only way is to put each in charge of a responsible man with a good watch, and let him start them. What time is the race? Oh, four o'clock. Well, I never yet saw a pony race that started on time; neither the ponies nor the boys are easy to handle, and I see there are ten of them. Watch them; it's after four, and they must be nearly ready to start.”

The ponies were strung out round the course, each with a “shepherd” standing to attention near its bridle, watch in hand. They could see Jim's great form standing sentinel over a tiny animal, whose diminutive rider was far too afraid of the huge Major to try to snatch even a yard of ground; nearer, Wally kept a wary eye on the experienced jockey on the blacksmith's racing mare, who was afraid of nothing, but nevertheless had a certain wholesome respect for the tall fellow who lounged easily against a tree near him, but never for an instant shifted his gaze. The shepherds were waiting for a signal from the official starter.

It came presently, a long shrill whistle, and simultaneously each guardian stepped back, and the released ponies went off like a flash—all save Bob's charge, who insisted on swinging round and bolting in the wrong direction, while his jockey sawed at his mouth in vain. Yawing across the track the rebel encountered the blacksmith's pony, who swerved violently in her swift course to avoid him, and lost so much ground that any chance she had in the race was hopelessly lost, whereat the blacksmith, who was standing on the hill, raved and tore his hair unavailingly. A smart little bay pony fought out the finish with Jim's tiny charge, and was beaten by a short head, just as Wally, walking quickly, came back to his party.

“That was a great race,” said Norah. “Wally, you shouldn't walk so fast on such a day. It makes one warm only to look at you.”

Wally answered with an absent air that was unlike his usual alertness. The girls, watching the ponies come in, noticed nothing, and presently he drew Mr. Linton aside.

“Did you notice that cloud, sir?” he asked, in a low voice. “I didn't until I was down on the track with the pony, looking in that direction. But it's twice the size it was when I went down.”

“I've been looking at it, and I don't like it,” said Mr. Linton. “It's smoke, I'm positive, and too near Billabong and the Creek to be comfortable. I think we'll make tracks for home, Wally. Have you seen Murty anywhere?”

As if in answer, Mr. O'Toole came running down the hill.
