They continued for half an hour on the ranch road, rising and dipping from point to point, yet mounting always higher above the great plain below. There the prairie stretched away, a hundred miles to the East and South, with never a lake nor a forest to catch the light, with not a cloud in the sky to cast a shadow. Yet over the broad, undulating expanse were lines and patches of varying color, changing and wavering from moment to moment, like mystic currents and eddies upon a heaving, tide-swept sea. Amy watched her companion furtively, ready to take umbrage at any lack of proper appreciation on his part; for this was what she liked best in all Colorado, this vast, mysterious prairie sea. Yet when she saw by Stephen's face that the spell had touched him too, when she noted the rapt gaze he sent forth, as he left his horse to choose his own way, she felt annoyed, unreasoningly, perversely annoyed. Somehow his look was too rapt, he was taking it too solemnly, he was too much in earnest! She had a longing to touch up her horse and gallop off to some spot where she might be unmolested, where she might think her own thoughts and receive her own impressions without seeing them accentuated, exaggerated in another person. There had never been any one before who seemed to feel just as she did about that view, and somehow she resented this intrusion upon what seemed like her own preserve. Of course there was but one explanation of all this high-strung sensitiveness in a healthy, natural girl like Amy Lovejoy. She had made a mistake, and she was finding it out. In those autumn days in the little New England town, she had fallen captive to an idea, a theory of life, a certain poetical incentive and aspiration; for months she had fed her imagination upon this new experience, and suddenly Stephen Burns had come, and by his personal presence asserted a personal claim. She had been unconsciously ignoring the personal element in their relation, which had, in the months of separation, become very indefinite and unreal to her. She had told her father that Stephen's eyes were brown, and she found that they were blue; she had described him as being tall, and he had turned out to be rather below the medium height; she had forgotten what his voice was like, and it seemed oppressively rich and full. "Better look out for your horse, Mr. Burns!" she said curtly. "He almost took a header a minute ago." "Did he?" said Stephen. "I did not notice. This is the view you told me about, is it not?" "Very likely," she returned, with affected indifference. "We Colorado people always do a good deal of bragging when we are in the East. We wear all our little descriptions and enthusiasms threadbare." "There was nothing threadbare about your account," Stephen protested. "It was almost as vivid as the sight itself." "We take things more naturally when we get back to them. Come, Jack, let's go faster!"
