To himself Mostyn muttered: "Sufficient unto the day is the evil thereof."

CHAPTER II.
MOSTYN SEES THE DERBY.

An hour before the big race Mostyn stood in the Paddock, by the side of his mentor, and pretended to pass a critical eye upon the horses generally, and upon Hipponous in particular.

The second favourite was a chestnut with three white stockings. His mane had been hogged, and he had—for a racehorse—an unusually large tail. Tyro as he was, Mostyn could understand the value of the large roomy flanks and magnificent barrel, and as the colt picked its way delicately round the circle, sweating slightly from excitement and glancing intelligently from side to side, it seemed as if he appreciated the fact that it was Derby Day, and realised the magnitude of the task before him.

A kaleidoscopic crowd surged round the horse, a crowd that Mostyn failed to understand till Royce explained that the "open sesame" to the Paddock could be obtained by the payment of a sovereign, which accounted for the general rubbing of shoulders and absence of class distinction.

Scraps of conversation, indistinctly overheard, amused, astonished, and perhaps instructed, him. There was a portly woman with a red face and a large feather hat, who pushed her way to the front, and said wheezingly to a thin little man at her side: "'Ullo, 'ere's Black Diamond."

"No, it ain't," responded her companion. "Look at the number. That's 'Ippernouse. He won the Middle Park Plate when I 'ad a dollar on 'im, and I'm going to put a couple o' quid on 'im to-day."

"I'll back Black Diamond," returned the fat woman, "because my first husband kept a small public called the 'Lord Napier' up past the 'Nag's Head' before we were married, and Black Diamond belongs to Lord Napier, so that's good enough for my money."

They drifted away and their place was taken by a couple of shrewd-looking club-men in long covert cloaks and bowler hats, with glasses slung over their shoulders. Mostyn heard one of them say to the other in an undertone: "Here's Hipponous. Look at his magnificent quarters. Don't forget to wire off immediately to Cork if he wins, and tell Dickson that I'll take the colt he has in his stables, brother to Hipponous, and if he throws the mare in I'll pay two thousand guineas for the pair."
