"Only a few minutes," you answer, wondering whether Theodore really supposes that you could canter, much less trot half an hour, even if stimulated by the music of the spheres.

"That's a pretty rider," he says, as a girl circles lightly past, sitting fairly well, and rising straight, but with her arms so much extended that her elbow is the apex of a very obtuse angle, though her forearms are horizontal. You explain this point to Theodore, who replies that she looks pretty, and seems to be able to trot for some time, whereupon your heart sinks within you. What will he say when he sees the necessary brevity of your performance?

Other riders enter: two or three men mounted on their own horses, beautiful creatures concerning whose value fabulous tales are told in the stable; the best rider of the school, very quietly and correctly dressed, and managing her horse so easily that the women in the gallery do not perceive that she is guiding him at all, although the real judges, old soldiers, a stray racing man or two, the other school pupils and the master—regard her admiringly, and the grooms, as they bring in new horses, keep an eye on her and her movements, as they linger on their way back to the stable.

"Her horse is very good," Theodore admits, "but I don't think much of her. Well, yes, she is pretty," he admits, as she executes the Spanish trot for a few steps and then pats her horse's shoulder; "it's pretty, but anybody could do it on a trained horse, couldn't they, sir?" he asks your master, who rides up, mounted on his own pet horse.

"Anybody who knew how. The horse has been trained to answer certain orders, but the orders must be given. An untrained horse would not understand the orders, no matter how good an animal he might be. Antinous might not have been able to ride Bucephalus, and I don't believe that Alexander could have coaxed Rosinante into a Spanish trot. It isn't enough to have a Corliss engine, or enough to have a good engineer: you must have them both, and they must be acquainted with one another. I don't believe that horse would do that for you."

"No, I don't think he would," Theodore says dryly, for he has been watching, and has reluctantly owned to himself that he does not see how the movement is effected. Meantime, you, Esmeralda, have been arduously devoting yourself to maintaining a correct attitude, and are rewarded by hearing somebody in the gallery wonder whether you represent the kitchen poker or Bunker Hill Monument.

"Don't mind," your master says, encouragingly. "It is better to be stiffly erect than to be crooked, and as for the person who spoke, she could not ride a Newfoundland dog," and with that he touches his hat, and rides lightly across the ring to speak to a lady whose horse has, in the opinion of the gallery, been showing a very bad temper, although in reality every plunge and curvet has been made in answer to her wrist and to the tiny spur which his rider wears and uses when needed. The lady nods in answer to something which the master says, the two draw near to the wall, side by side, the others fall in behind them, and the band begins a waltz, playing rather deliberately at first, but soon slightly accelerating the time.

There is very little actual need of guiding your horse, Esmeralda, because long habit has taught him what to do at a music-ride, but you do right to continue to endeavor to make him obey you. Should he stumble; should that man riding before you and struggling to make his horse change his leading foot fail in the attempt, and cause the poor creature to fall; should the rider behind you lose control of her horse, your firm hold of the reins would be of priceless value to you, but now the waltz rhythm suddenly changes to that of a march, and your horse begins to trot, slowly and with little action at first, and then with a freer, longer stride which really lifts you out of the saddle, sending you rather too high for grace, indeed, but making the effort very slight for you, and enabling you to think about your elbows, and sitting to the right and keeping your right shoulder back and your right foot close to the saddle and pointing downward, and your left knee also close, and "about seventy-five other things," as you sum up the case to yourself. Thanks to this, you are enabled to continue until the music stops, and Theodore says, approvingly, "Well, you can ride a little."

"A very little," your master says. She has learned something, of course, but it would be the unkindest of flattery for me to fell her that she does well."

"One must begin to ride in early childhood," Theodore says.
