But when it comes to a horse, a man's heart speaks for itself, and if he has sufficient knowledge of the king of beasts he will choose a sympathetic mount. A dainty woman loves a neat-stepping saddle-horse; a philosopher likes a nodding, stumble-footed nag which will jog all day long and care not a whit whether it goes up dale or down.

To know the six wild riders who galloped over the white reaches of the mountain-desert this night, certainly their horses should be studied first and the men secondly, for the one explained the other.

They came in a racing triangle. Even the storm at its height could not daunt such furious riders. At the point of the triangle thundered a mighty black stallion, his muzzle and his broad chest flecked with white foam, for he stretched his head out and champed at the bit with ears laid flat back, as though even that furious pace gave him no opportunity to use fully his strength.

He was no cleanly cut beauty, but an ugly headed monster with a savagely hooked Roman nose and small, keen eyes, always red at the corners. A medieval baron in full panoply of plate armor would have chosen such a charger among ten thousand steeds, yet the black stallion needed all his strength to uphold the unarmored giant who bestrode him, a savage figure.

When the broad brim of his hat flapped up against the wind the moonshine caught at shaggy brows, a cruelly arched nose, thin, straight lips, and a forward-thrusting jaw. It seemed as if nature had hewn him roughly and designed him for a primitive age where he could fight his way with hands and teeth.

This was Jim Boone. To his right and a little behind him galloped a riderless horse, a beautiful young animal continually tossing its head and looking as if for guidance at the big stallion.

To the left strode a handsome bay with pricking ears. A mound interfered with his course, and he cleared it in magnificent style that would have brought a cheer from the lips of any English lover of the chase.

Straight in the saddle sat Dick Wilbur, and he raised his face a little to the wind, smiling faintly as if he rejoiced in its fine strength, as handsome as the horse he rode, as cleanly cut, as finely bred. The moon shone a little brighter on him than on any others of the six stark riders.

Bud Mansie behind, for instance, kept his head slightly to one side and cursed beneath his breath at the storm and set his teeth at the wind. His horse, delicately formed, with long, slender legs, could not have endured that charge against the storm save that it constantly edged behind the leaders and let them break the wind. It carried less weight than any other mount of the six, and its strength was cunningly nursed by the rider so that it kept its place, and at the finish it would be as strong as any and swifter, perhaps, for a sudden, short effort, just as Bud Mansie might be numbed through all his nervous, slender body, but never too numb for swift and deadly action.

On the opposite wing of the flying wedge galloped a dust-colored gray, ragged of mane and tail, and vindictive of eye, like its down-headed rider, who shifted his glance rapidly from side to side and watched the ground closely before his horse as if he were perpetually prepared for danger.
