The day was rather windy, and as she drove up Park Lane she had her work cut out for her in the matter of management. The cobs had been newly clipped, and all their nerves appeared to be outside their skins. This Mildred thoroughly enjoyed; she was conscious of the mastery over brute strength which makes the fascination of dealing with horses, and she loved to know that Box longed to bolt and could not manage it, and that Cox wanted to shy at every carriage that passed but did not dare, for that his nerves were outside his skin, and he was aware who sat behind him with whip alert. "The heavenly devils!" thought Mildred to herself as they avoided a curbstone on the one hand by a hair-breadth and a bicycle on the other by half that distance.
Like all fine whips, she infinitely preferred to drive in the streets than in the Park, but to-day they were horribly crowded, and she turned in through Stanhope Gate with the idea of letting the cobs have a good trot through the Park and come out at the Albert Gate. The day was so divine that she thought she would perhaps go out of town, and lunch at Richmond or somewhere, returning in the afternoon. She was dining out that night at Blanche Devereux's, who had a Mexican band coming, which, according to her account, was so thrilling that you didn't know whether you were standing on your head or your heels. This sounded quite promising; she liked a _décolleté_ evening.
So Box and Cox had their hearts' desire, and flew down the road inside the Park parallel to Park Lane. Here a motor-car, performing in a gusty and throbbing manner, was a shock to their sense of decency, and they made a simultaneous dash for the railings, until recalled to their own sense of decency by a vivid cut across their close-shaven backs and a steady pull on their mouths to show them that the whip was punitive, not suggestive of faster progress. The progress, indeed, was fast enough to satisfy even Mildred, who, however, was enjoying herself immensely. Both cobs had their heads free (she, like the wise woman she was in matters of horseflesh, abominating bearing-reins even for the brougham horses, and knowing that for speed they are death and ruin), necks arched, and were stepping high and long. Then, as they came to the bend of the road of the Ladies' Mile, she indicated the right-hand road, and found that they were a little beyond her control. Simultaneously a wayward gust picked up a piece of wandering newspaper and blew it right across Box's blinkers; from there it slid gradually on to Cox's. The same moment both heads were up, and, utterly beyond her control, they bolted straight for the gate at Hyde Park Corner. It is narrow; outside the double tide of traffic roared and jostled.
