"I thought I saw you," said Candace, simply.

She was looking straight at Georgie as she spoke, and was surprised to see her flush suddenly, and then turn as suddenly pale. Her change of color was so marked that her mother could scarcely have failed to notice it, had her attention not been for the moment occupied by Frederic, who just brought out a note which required an answer. Gertrude was looking another way; only Candace noticed Georgie's unwonted emotion. Nothing more was said about Fort Greene at the time; but a little later, when she was in her room smoothing her hair for dinner, Georgie tapped at the door.

"Cannie," she said, "I'm going to ask you not to say anything more to anybody about having seen Berry and me on Washington Street to-day."

"Certainly, I won't," replied Candace, making in her surprise one of those hasty promises which are so often repented of afterward; "but why not?"

"Oh, well, there are no very important reasons; it's just that I would rather you wouldn't."

"Very well." But Candace felt vaguely dissatisfied with this explanation, and a little curious.

She thought of this promise, and of Georgie's odd manner of exacting it from her, as she fell asleep that night, and again the next morning; but gradually it faded from her mind, until, about ten days later, something occurred to revive the remembrance. Mrs. Joy called to ask two of the girls to drive with Berry and herself to see the polo play. Gertrude happened to be out; so Candace fell heir to her share of the invitation. Mrs. Gray was glad to have her go. She herself did not often visit the Polo Ground, and she thought Candace would enjoy seeing a match, and that it would be something pleasant for her to remember.

The Polo Ground is a large enclosure to the south of Spring Street, and well out of the town. It is shut in by a high paling, built with the intention of excluding every one who does not pay for the pleasure of witnessing the game. Nature, however,—that free-handed dame,—has frustrated this precaution by providing, close to the paling, a little rocky bluff, or rise of land, not owned by the Polo Association, whose top commands a clear view over the fence; and on polo days this point of vantage is usually well filled by on-lookers of an impecunious description. There was quite a little crowd on the brow of "Deadhead Hill," as it is called, when Mrs. Joy's carriage turned in at the gates; and she glanced that way and said, "It is really too bad about that hill!" in a dissatisfied tone, as if the enjoyment of these non-subscribers jarred in some way, or interfered with the pleasure for which she herself was forced to pay a round price.

Inside the gate appeared a large railed enclosure, with a wicket at either end; and about this carriages full of gay people were drawn up in rows, two or three abreast. The ponies which were to be used in the game were being led up and down on the farther side of the ground, where was a range of out-buildings. Presently a bell rang. There was a little confusion of unblanketing and mounting, and eight riders armed with long mallets rode forward. Four wore red caps, and four blue; and the two colors ranged themselves opposite each other at the wickets. The umpire tossed a little ball into the middle of the ground, and the game began.

Candace was at first rather inclined to laugh at the riders, who were so much too tall for their little steeds that in some cases their legs seemed in danger of hitting the ground; but before long she had become so interested in the game and the bold riding that she no longer felt inclined to laugh. The object of each side was to drive the ball through its own wicket; and to effect this a great deal of both courage and skill were required, not only on the part of the horsemen, but of the ponies as well. More than once all the eight seemed to be collected in a breathless tangle about and above the ball, crowding, pushing, struggling for the chance at a stroke; and in such cases the ponies seemed to divide the excitement with their masters, and fenced and curved and described indescribably short circles, regardless of the danger of getting a hard rap from the cruel mallets on their own poor little hoofs. Then, when some lucky hit sent the ball spinning across the ground, it was quite beautiful to see the alacrity with which the little creatures, of their own accord, as it were, rushed, after it, obeying the slightest indication from rein or spur, and apparently measuring the distance and the opportunities as accurately as their riders. The beat of their small hoofs on the smooth ground was so swift and even that it was more like a rustle than a rush. To and fro flew the ball, now almost at the blue wicket, then reached and sent back in the very nick of time by one of the red champions. Candace was so fascinated that she had no eyes for any one else till, turning her head by accident, her eye lighted upon a face in the crowd near the carriage; and with a flash of recognition she knew that it was the stranger of whom she had caught that momentary glimpse at Fort Greene. Involuntarily she glanced at Berry Joy and Georgie, and perceived that the former had seen the man also and was trying to look as if she had not seen him, while the latter was honestly unconscious. There was something odd about the man's manner, which kept Candace's attention fixed. He seemed to be standing carelessly among other spectators watching the game, and yet by a series of dexterous movements and small shiftings of position he was gradually edging toward the carriage. Presently a forward step more decided than the rest brought him close to it. Georgie saw him now. A deep color flushed her face; she lowered her parasol as if to hide it.
