“There’s a lady,” the colonel was shouting.  “Go it, girl.  Go it, beauty.  Lady Mary!  Lady Mary!”

Marianne raised her field glasses and studied the rush of horses through the fog of dust.

“It’s just as I thought,” she cried, without lowering the glasses.  “The scoundrel is pulling Alcatraz!  He rides as if he were afraid of something—­afraid that the horse might break away.  Look, Mr. Corson.”

“I dunno,” said Corson.  “It sure does look sort of queer!”

“Why, he’s purposely keeping that horse in a pocket.  Has him on the rail.  Oh, the villain!” It was a cry of shrill rage. “He’s sawing on the bit! And the chestnut has his ears back.  I can see the glint of his eyes.  As if he wants to run simply because he is being held.  But there—­ there—­there!  He’s got the bit in his teeth.  His head goes out.  Mr. Corson, is it too late for Alcatraz to win the race?”

She dropped the glasses.  There was no need of them now.  Rounding into the long home stretch Cordova made a last frightened effort to regain control and then gave up, his eyes rolling with fear; Alcatraz had got his head.

He ran his own race from that point.  He leaped away from the cowponies in the first three strides and set sail for the leaders.  Because of his ragged appearance his name had been picked up by the crowd and sent drifting about the field; now they called on him loudly.  For every rancher and every ranch-hand in Glosterville was summoning Alcatraz to vindicate the range-stock against the long-legged mares which had been imported from the East for the sole purpose of shaming the native products.  The cry shook in a wailing chorus across the field:  “Alcatraz!” and again:  “Alcatraz!” With tingling cowboy yells in between.  And mightily the chestnut answered those calls, bolting down the stretch.

The riders of the mares had sensed danger in the shouting of the crowd, and though their lead seemed safe they took no chances but sat down and began to ride out their mounts.  Still Alcatraz gained.  From the stretching head, across the withers, the straight-driving croup, the tail whipped out behind, was one even line.  His ears were not flagging back like the ears of a horse merely giving his utmost of speed; they were dressed flat by a consuming fury, and the same uncanny rage gleamed in his eyes and trembled in his expanding nostrils.  It was like a human effort and for that reason terrible in a brute beast.  Marianne saw Colonel Dickinson with the fingers of one hand buried in his plump breast; the other had reared his hat aloft, frozen in place in the midst of the last flourish; and never in her life had she seen such mingled incredulity and terror.

She looked back again.  There were three sections to the race now.  The range ponies were hopelessly out of it.  The Coles horses ran well in the lead.  Between, coming with tremendous bounds, was Alcatraz.  He got no help from his rider.  The light jockey on Lady Mary was aiding his mount by throwing his weight with the swing of her gallop, but Manuel Cordova was a leaden burden.  The most casual glance showed the man to be in a blue funk; he rode as one astride a thunderbolt and Alcatraz had both to plan his race and run it.
