Four-Pound-the-Second had missed Jackaroo's quarters by half a length; but the big horse never faltered in his stride, charging on like a bull-buffalo, and rising at the water as the mare landed over it.

The old man dropped his glasses, and settled back on his heels.

"What next?" he said.

"Can't do much now, I guess," answered Silver comfortably.

Old Mat turned in his lips.

"Watch it, sir," he said. "There's millions in it."

As the favourite and the outsider swept away for the second round in a pursuing roar, the width of the course lay between them. The mare hugged the rails; the brown horse swung wide on the right.

"You're giving her plenty of room, Mr. Woodburn," said the White Hat in front.

"Yes, my lord," Mat answered. "'Don't crowd her,' I says. 'She likes a lot o' room. So do Chukkers.'"

Just clear of the course outside the rails, under the Embankment, a little group of police made a dark blue knot about the stretcher on which Boy Braithwaite had been taken from the course. As the brown horse swept hard by the group a blob of yellow thrust up suddenly above the rails amid the blue. It was too much even for Four-Pound. He shied away and crashed into his fence. Only his weight and the speed at which he was travelling carried him through. A soughing groan went up from the Grand Stand, changing to a roar, as the great horse, quick as a goat, recovered himself and settled unconcernedly to his stride again.
