"She won't really—it's all brag!" sneered Gladys.

"Is it indeed, Miss Gladys Merriman? Just wait till this afternoon, and I'll undeceive you."

"I'll wait to buy the box of chocolates, though," sniggered Gladys.

None of the girls really believed that Gipsy was in earnest, yet they sallied forth to the hockey field that afternoon with a certain amused anticipation. The news had been spread abroad in the Lower School, so the Juniors had assembled ten minutes in advance of their ordinary time on the chance of witnessing what Hetty called "the circus-riding". The hockey ground was divided from the meadow by a strong wooden paling, on the farther side of which the colt, a shaggy, ungroomed, raw-boned specimen of horse-flesh, was feeding.

"It is as frisky as—well, as a colt!" said Mary Parsons. "You'd better not try to catch that creature, Gipsy."

"It'll pretty soon kick her off if she does!" said Alice O'Connor. "Well, Gipsy? Going to turn tail at the last minute? You'd best give in!"

"Rather not!" returned Gipsy. "When I'm dared to do a thing, I do it—or have a good try, at any rate. If I'm not galloping round the field in ten minutes, you may count me done. Hetty, you keep time!" And without stopping to listen to any more remonstrances, she climbed over the palings.

She had brought some bread with her, and she walked very gently towards the colt, holding out her bait, and making a series of chirruping sounds calculated to win its confidence. The rough little creature paused in its task of tearing the grass, and eyed her doubtfully. It had been petted, however, by the boys at the farm to which it belonged (a fact of which Gipsy was well aware when she accepted Gladys's challenge), and had a marked partiality for such dainties as bread, sugar, and carrots. Though Gipsy was a stranger, it evidently considered she was familiar with horse language, and encouraged by her chirrups it advanced cautiously, rolling its eyes a little, and sniffing suspiciously. Gipsy stood still, and without moving a muscle let it come quite near and inspect her. She held the bread on the palm of her left hand; her right hand was ready for action when necessary.

The row of girls leaning over the palings watched in dead silence. Summoning up its courage, the colt stretched out its nose to take the tempting bread. Gipsy let it get the coveted morsel well within its lips, then seized the halter with her left hand and the long chestnut mane with her right, and with a sudden agile bound and scramble flung herself across its back. It was so quickly and neatly done that the bystanders held their breath with admiration. Gipsy's horsemanship was evidently no idle boast, if she could perform so difficult a feat of gymnastics with such comparative ease. Meantime the colt, astonished and enraged at finding a burden on its back, was trying buck-jumping, and Gipsy had to cling to mane and halter to keep her seat. At this critical moment the Seniors and the mistresses arrived on the scene. Miss Poppleton's amazement and horror at finding one of her pupils mounted on the back of an unbroken colt were almost too great for words.

"Stop her! Stop her!" she gasped wildly. "Oh, for pity's sake, somebody stop her!"
