Inquiry among those qualified to know, led to the estimate of the number of all bears in the Park to be between five hundred and one thousand. Considering that there are some three thousand square miles of land, that there were nearly sixty thousand elk, besides hundreds of bison, antelope, mountain sheep, and similar animals, this does not seem improbable. I am aware that recent statements are to the effect that there were only forty grizzlies there. This is palpably an underestimate, and probably takes into account only those that frequent the dumps. Frost believes that there are several hundred grizzlies in the Park, many of which range out in the adjacent country. So we felt no fear of decimating their ranks, and had every hope of seeing many. In fact, their number has so increased in recent years that they have become a menace and require killing off.

During the past five years four persons have either been mauled or killed by grizzlies in Yellowstone. One of these was a teamster by the name of Jack Walsh. He was sleeping under his wagon at Cold Springs when a large bear seized him by the arm, dragged him forth and ripped open his abdomen. Walsh died of blood poison and peritonitis a few days later. Frost himself was attacked. He was conducting a party of tourists through the preserve and had just been explaining to them around the camp-fire that there was no danger of bears. He slept in the tent with a horse wrangler by the name of Phonograph Jones. In the middle of the night a huge grizzly entered his tent and stepped on the head of Jones, peeling the skin off his face by the rough pressure of his paw. The man waked with a yell, whereupon the bear clawed out his lower ribs. The cry roused Frost, who having no firearms, hurled his pillow at the bear.

With a roar, the grizzly leaped upon Ned, who dived into his sleeping bag. The animal grasped him by the thighs, and dragged him from the tent out into the forest, sleeping bag and all. As he carried off his victim, he shook him from side to side as a dog shakes a rat. Frost felt the great teeth settle down on his thigh bones and expected momentarily to have them crushed in the powerful jaws. In a thicket of jack pines over a hundred yards from camp, the bear shook him so violently that the muscles of the man's thighs tore out and he was hurled free from the bag. He landed half-naked in the undergrowth several yards away.

While the frenzied bear still worried the bedding, Frost dragged himself to a near-by pine and pulled himself up in its branches by the strength of his arms.

The camp was in an uproar; a huge fire was kindled; tin pans were beaten; one of the helpers mounted a horse and by circling around the bear, succeeded in driving him away.

After first aid measures were administered, Frost was successfully nursed back to health and usefulness by his wife. But since that time he has an inveterate hatred of grizzlies, hunting them with grim persistency.

It is said that nearly forty obnoxious grizzlies were shot by the Park rangers after this episode and Frost was given a permit to carry a weapon. We found later that he always went to sleep with a Colt automatic pistol strapped to his wrist.

We planned to enter the Park in two parties. One, comprised of Frost, the cook, horse wrangler, my brother, and his friend, Judge Henry Hulbert, of Detroit, was to proceed from Cody and come with a pack train across Sylvan Pass. Our party consisted of Arthur Young and myself; Mr. Compton was unexpectedly prevented from joining us by sickness in his family. We were to journey by rail to Ashton. This was the nearest point to Yellowstone Station on the boundary of the reservation that could be reached by railroad in winter.

We arrived at this point near the last of May 1920. The roads beyond were blocked with snow, but by good fortune, we were taken in by one of the first work trains entering the region through the personal interest and courtesy of the superintendent of the Pocatello division.

We had shipped ahead of us a quantity of provisions and came outfitted only with sleeping bags, extra clothing, and our archery equipment. This latter consisted of two bows apiece and a carrying case containing one hundred and forty-four broad-heads, the finest assembly of bows and arrows since the battle of Crecy.
