Once Lynn gave a low cry and pointed to the crest of a rise where a magnificent stallion with his band of mares was outlined against the bright blue May sky.

"Horses," said Matt. "They've run wild."

The dirt road wound on and on, coming at length to a black asphalt highway. A sign across the highway read:

LOUISVILLE
14 MILES

"Louisville?" said Nesbit. "That's a fair-sized city. Million and a half population."

Lynn frowned. "It's in Kentucky, isn't it?"

"Yes. On the Ohio, about a hundred and fifty miles downriver from Cincinnati."

"What time is it?" Matt asked Captain Bascom.

The captain glanced at his watch. "Twenty-three after ten. We've got time."

"Mark this road," Matt warned them. "We want to be able to find our way back."
