But seconds counted triply now, and the halt and the time they would spend getting up impetus all told in favor of the fugitive.
Thirty-five miles, or thereabouts, since they left Rickett that morning, and still the black ran smoothly, with a lilt to his gallop.

Dan Barry lifted his head and his whistling soared and pulsed and filled the air.
It made Bart come back to him; it made Satan toss his head and glance at the master from the corner of his bright eye, for this was an assurance that the battle was over and the rest not far away.
On they drove, straight as a bird flies for Caswell City, and Black Bart, ranging ahead among the hills, was picking the way once more.

If the stallion were tired, he gave no sign of it.

The sweep of his stride brushed him past rocks and shrubs, and he literally flowed uphill and down, far different from the horses which scampered in his rear, for they pounded the earth with their efforts, grunting under the weight of fifty pound saddles and heavy riders.

Another handicap checked them, for while Satan ran on alone, freely, the bunched pursuers kept a continual friction back and forth.
