Jack turned crimson. She had meant to be good to Elizabeth, but it had never occurred to her to give up her horseback ride on her account.
"I am sorry, Elizabeth," she answered uncomfortably. "Perhaps Mr. Drummond would exchange me for Jean or Olive. I didn't know you cared so much about my driving with you."
Jean and Olive both shook their heads decidedly, and Frieda gazed at Elizabeth in stern disapproval; but Mr. Drummond, who was also accustomed to having his own way, settled the matter. "You'll take the ride with me this morning, Miss Ralston," he announced, "then you can devote yourself to your friend later in the day if you like." And Elizabeth was obliged to be content.
Jack was convinced she had never had such a wonderful ride in her life, never had she felt in such glorious health and spirits. Her horse moved along under her with a gait to which she was entirely unaccustomed. Only shaggy bronchos and rough western ponies had been her mounts until to-day, and now she was on the back of a beautiful Kentucky thoroughbred, riding over a perfect road, very different from the long stretches of sand on the plains. The two riders had galloped on for several miles without a word, Peter keeping a little in the background to enjoy the wonderful grace and ease of Jack's horsemanship.
Suddenly the girl reined in her horse and the man slowed down. "I want to thank you for this glorious ride now while I have the chance," she said simply. "Sometimes I wish I could spend my whole life in the saddle, I love it so. I hope I wasn't selfish in not driving with Elizabeth Harmon. I am so horribly sorry for people who can't ride and walk and swim and enjoy the things I do, I would do nearly anything in the world for them," she ended wistfully. And for a long time afterward Mr. Drummond remembered what Jack had said and her beauty and careless vigor as she spoke, with her hands holding her mare's reins lightly but firmly and her body keeping perfect rhythm with its every movement.
The two riders came to the neighborhood of the great geyser a little in advance of the coaching party. They rode up to within a reasonable distance of the queer, symmetrical, cone-shaped hill. There were a few people waiting about, but the place was quite peaceful and showed no sign of the leaping torrent of water Jack anticipated. She was intending to dismount from her horse when the stage arrived. Suddenly a roar, like a giant's snort, came from beneath the earth and almost instantly steaming water began to rise through the mouth of the cone in glistening, gleaming bubbles, then a giant cataract reared itself. Jack and Peter Drummond had been too surprised at the geyser's sudden display of its powers to get off their horses at once, and Jack's thoroughbred was not trained to endure any such exhibition of the unknown forces of nature. Her whole body quivered as though she had been struck a cruel blow, then, making a leap straight into the air and coming down on her two hind feet, she began to dance and curvet and leap about as though bewitched. Mr. Drummond had a horrified moment of fearing Jack would be dreadfully injured, but he was too engaged in quieting his own horse's terror to give her aid. The coaching party arrived on the scene at this minute and they were torn between interest in the marvelous geyser and concern for Jack's safety.
Jack proved her horsemanship by recognizing that the high-strung animal she was riding required a different treatment from one of her rough ponies. Never once did she use her whip on the pretty mare, but talked to her in a gentle, soothing tone, keeping her nose turned directly toward the roaring stream of water, so that the mare should not bolt and run on hearing extraordinary noises at her back.
In four or five minutes two hundred and fifty thousand gallons of scalding water had been raised one hundred and fifty feet in the air, held for a little time and then dashed down to earth again, and "Old Faithful" was once more peaceful for exactly an hour and ten minutes.
But in this period Jacqueline had brought her horse to a quivering standstill not far from the geyser. Elizabeth Harmon was pale with fright and her eyes were full of tears of apprehension, but Frieda was merely interested in her sister's performance, as she had not the least idea of her being hurt.
In a few seconds after the excitement had passed, Jim Colter leapt out of the stage and walked toward Jack. "Bravo!" he said, as she slid off her mare, handing her reins to Mr. Drummond.
