A single glance showed me several cows running as if bewildered, and near them a big white wolf pulling down a calf. Another white wolf stood not far off. My horse jumped as if he had been shot; and the realization darted upon me that here was where the certain something began. Spot—the mustang had one black spot in his pure white—snorted like I imagined a blooded horse might, under dire insult. Jones's bay had gotten about a hundred paces the start. I lived to learn that Spot hated to be left behind; moreover, he would not be left behind; he was the swiftest horse on the range, and proud of the distinction. I cast one unmentionable word on the breeze toward the cabin and Frank, then put mind and muscle to the sore task of remaining with Spot. Jones was born on a saddle, and had been taking his meals in a saddle for about sixty-three years, and the bay horse could run. Run is not a felicitous word—he flew. And I was rendered mentally deranged for the moment to see that hundred paces between the bay and Spot materially lessen at every jump. Spot lengthened out, seemed to go down near the ground, and cut the air like a high-geared auto. If I had not heard the fast rhythmic beat of his hoofs, and had not bounced high into the air at every jump, I would have been sure I was riding a bird. I tried to stop him. As well might I have tried to pull in the Lusitania with a thread. Spot was out to overhaul that bay, and in spite of me, he was doing it. The wind rushed into my face and sang in my ears. Jones seemed the nucleus of a sort of haze, and it grew larger and larger. Presently he became clearly defined in my sight; the violent commotion under me subsided; I once more felt the saddle, and then I realized that Spot had been content to stop alongside of Jones, tossing his head and champing his bit.

"Well, by George! I didn't know you were in the stretch," cried my companion. "That was a fine little brush. We must have come several miles. I'd have killed those wolves if I'd brought a gun. The big one that had the calf was a bold brute. He never let go until I was within fifty feet of him. Then I almost rode him down. I don't think the calf was much hurt. But those blood-thirsty devils will return, and like as not get the calf. That's the worst of cattle raising. Now, take the buffalo. Do you suppose those wolves could have gotten a buffalo calf out from under the mother? Never. Neither could a whole band of wolves. Buffalo stick close together, and the little ones do not stray. When danger threatens, the herd closes in and faces it and fights. That is what is grand about the buffalo and what made them once roam the prairies in countless, endless droves."

From the highest elevation in that part of the range we viewed the surrounding ridges, flats and hollows, searching for the buffalo. At length we spied a cloud of dust rising from behind an undulating mound, then big black dots hove in sight.

"Frank has rounded up the herd, and is driving it this way. We'll wait," said Jones.

Though the buffalo appeared to be moving fast, a long time elapsed before they reached the foot of our outlook. They lumbered along in a compact mass, so dense that I could not count them, but I estimated the number at seventy-five. Frank was riding zigzag behind them, swinging his lariat and yelling. When he espied us he reined in his horse and waited. Then the herd slowed down, halted and began browsing.

"Look at the cattalo calves," cried Jones, in ecstatic tones. "See how shy they are, how close they stick to their mothers."

The little dark-brown fellows were plainly frightened. I made several unsuccessful attempts to photograph them, and gave it up when Jones told me not to ride too close and that it would be better to wait till we had them in the corral.

He took my camera and instructed me to go on ahead, in the rear of the herd. I heard the click of the instrument as he snapped a picture, and then suddenly heard him shout in alarm: "Look out! look out! pull your horse!"

Thundering hoof-beats pounding the earth accompanied his words. I saw a big bull, with head down, tail raised, charging my horse. He answered Frank's yell of command with a furious grunt. I was paralyzed at the wonderfully swift action of the shaggy brute, and I sat helpless. Spot wheeled as if he were on a pivot and plunged out of the way with a celerity that was astounding. The buffalo stopped, pawed the ground, and angrily tossed his huge head. Frank rode up to him, yelled, and struck him with the lariat, whereupon he gave another toss of his horns, and then returned to the herd.

"It was that darned white nag," said Jones. "Frank, it was wrong to put an inexperienced man on Spot. For that matter, the horse should never be allowed to go near the buffalo."
