It became a matter of desperate necessity to overtake that will-o'-the-wisp chauffeur and observe his passenger. Great expectations seemed to be justified by the fact that nearly every policeman saluted her and smiled so pleasantly and so pleasedly that the smile lingered after she was far past.

Forbes noted, too, that the people she bowed to in other cars or on the sidewalk seemed to be important people, and yet to be proud when her hat gave a little wren-like nod in their directions.

At Fifty-first Street, in front of the affable gray Cathedral, there was a long and democratic delay while a contemptuous teamster, perched atop a huge steel girder, drove six haughty stallions across the Avenue; drove them slowly, and puffed deliberate smoke in the face of the impatient aristocracy.

Here a dismounted mounted policeman paced up and down, followed by a demure horse with kindly eyes. This officer paused to pass the time of day with the mysterious woman, and the horse put his nose into the car and accepted a caress from her little gloved hand. Again Forbes heard her voice:

"You poor old dear, I wish I had a lump of sugar."

It was to the horse that she spoke, but the officer answered:

"The sight of you, ma'am, is enough for um."

Evidently he came from where most policemen come from. The lady laughed again. She was evidently not afraid of a compliment. But the policeman was. He blushed and stammered:

"I beg your pairdon, Miss—"

He gulped the name and motioned the traffic forward. Forbes was congratulating himself that at least she was not "Mrs." Somebody, and his interest redoubled just as the young woman leaned forward to speak to her chauffeur. She had plainly seen that there was a policeless space ahead of her, for the driver put on such speed that he soon left Forbes and his stage far in the rear.
