El Capitan, too, seemed to share her uneasiness. Tossing his head, tugging at the bridle reins and pawing the ground and starting nervously, he turned this way and that, signifying his desire to be away. But just as Barbara, on the point of yielding to his impatience and her own feeling of fear, lifted the reins to turn toward Kingston again, he threw up his head with a loud neigh and with ears pointed looked away toward the south, standing rigid and motionless as a horse of stone. A cloud of dust rising from the trail told her that someone was approaching. Instantly the girl's feeling of fear vanished. She laughed aloud.
"Company is coming, Capitan," she said. "Shall we wait until we see who it is? We can easily run away if we don't like his looks."
As she finished speaking, the light wind that was just strong enough to carry the dust with the coming rider shifted for a moment and revealed the horseman clearly. Barbara, not wishing to appear as though waiting, started ahead toward Kingston, while the stranger, evidently catching sight of a horse and rider on the road ahead and desiring company, quickened his pace.
Barbara glanced over her shoulder. "Shall we run, Capitan? No, we'll not run yet. But be ready." Again she glanced quickly back. "It's no one we know, Capitan. Be ready."
Nearer and nearer came the stranger.
When she heard the sound of his horse's feet on the sand Barbara turned again, this time openly. Then she laughed. "I don't think we'll run this time, Capitan."
A moment later the horseman had overtaken her.
"Good morning, Mr. Holmes. How do you do?"
"Miss Worth!"
Had the engineer checked his horse so suddenly a few months before he would undoubtedly have gone over the animal's head. El Capitan also stopped, while the man and the girl sat looking at each other, Barbara smiling at the man's surprise.
