Sarah laughed merrily, and boldly struck the animal with her whip. It made Mr. Kerchey gasp to see him bound and plunge. But she kept her balance miraculously.

After seeing that every girth was well fastened, and every fair rider safely mounted, Chester leaped into his own saddle from the turf, without touching foot to stirrup. But he dismounted again immediately, smothering his laughter as well as he could.

All the gentlemen were mounted, except Mr. Kerchey.

His horse, excited by seeing his mate, governed by Sarah, dance about the yard, would not stand still an instant, or come up to the block. Harry Dustan, laughing at his distress, had cantered gayly away with Miss Sedley, the "school-ma'am." Only Chester was thoughtful enough to go to Mr. Kerchey's relief.

The latter, heated, agitated, and wofully perplexed, was beginning to see that riding horseback was a far more serious affair than he had imagined. He witnessed the bold riding of his neighbors with dismay. Galloping was to him a perfect mystery. His courage and ambition had never gone beyond a gentle trot. The mere thought of dashing off side by side with Sarah made him dizzy.

"Can't you mount?" asked Chester, soberly, considering the circumstances.

"No—I—that is—perhaps—on the whole—I'd better not—ah—attempt it."

"Oh, that won't do! What will the girls say?"

"But, you see—it is all—ah—new to me," stammered Mr. Kerchey.

"You'll get into the way of it at once," replied Chester, in an encouraging tone. "It's as easy as running down hill, or running up—an account. Now,"—he wheeled the horse to the block,—"put your leg over the saddle. No! the other leg,—your right one,—unless you want to ride backwards."
