Month after month through the sharp mountain winter, so long as the snow was not whirling through the air in clouds too dense to penetrate, Van and his master had their joyous gallops. Then came the spring, slow, shy, and reluctant as the springtide sets in on that high plateau in mid-continent, and Van had become even more thoroughly domesticated. He now looked upon himself as one of the family, and he knew the dining-room window, and there, thrice each day and sometimes at odd hours between, he would take his station while the household was at table and plead with those great soft brown eyes for sugar. Commissary-bills ran high that winter, and cut loaf-sugar was an item of untold expenditure. He had found a new ally and friend,--a little girl with eyes as deep and dark as and browner than his own, a winsome little maid of three, whose golden, sunshiny hair floated about her bonny head and sweet serious face like a halo of light from another world. Van "took to her" from the very first. He courted the caress of her little hand, and won her love and trust by the discretion of his movements when she was near. As soon as the days grew warm enough, she was always out on the front piazza when Van and I came home from our daily gallop, and then she would trot out to meet us and be lifted to her perch on the pommel; and then, with mincing gait, like lady's palfrey, stepping as though he might tread on eggs and yet not crush them, Van would take the little one on her own share of the ride. And so it was that the loyal friendship grew and strengthened. The one trick he had was never ventured upon when she was on his back, even after she became accustomed to riding at rapid gait and enjoying the springy canter over the prairie before Van went back to his stable. It was a strange trick: it proved a fatal one. No other horse I ever rode had one just like it. Running at full speed, his hoofs fairly flashing through the air and never seeming to touch the ground, he would suddenly, as it were, "change step" and gallop "disunited," as we cavalrymen would say. At first I thought it must be that he struck some rolling stone, but soon I found that when bounding over the soft turf it was just the same; and the men who knew him in the days of his prime in Arizona had noted it there. Of course there was nothing to do for it but make him change back as quick as possible on the run, for Van was deaf to remonstrance and proof against the rebuke of spur. Perhaps he could not control the fault; at all events he did not, and the effect was not pleasant. The rider felt a sudden jar, as though the horse had come down stiff-legged from a hurdle-leap; and sometimes it would be so sharp as to shake loose the forage-cap upon his rider's head. He sometimes did it when going at easy lope, but never when his little girl-friend was on his back: then he went on springs of air.
