The first day was to be an easy one—twelve miles and camp. "Twelve miles!" said the experienced riders. "Hardly a Sunday morning canter!" But a mountain mile is a real mile. Possibly they measure from peak to peak. I do not know. I do know that we were almost six hours making that twelve miles and that for four of it we led our horses down a mountain-side over a vacillating path of shale. Knees, that up to that point had been fairly serviceable, took to chattering. Riding-boots ceased to be a matter of pride and emerged skinned and broken. The horses slid and stumbled. And luncheon receded.

Down and down! Great granite cliffs of red and blue and yellow across the valley—and no luncheon! Striped squirrels hiding in the shale—and no luncheon! A great glow of moving blood through long-stagnant vessels, deep breaths of clear mountain air, a camera dropped on the trail, a stone in a horse's foot—and no luncheon!

Two o'clock, and we were down. The nervous woman who had never been on a horse before was cinching her own saddle and looking back and up. The saddle tightened, she sat down and emptied her riding-boots of a few pieces of rock. Her silk stockings were in tatters.

"I feel as though my knees will never meet again," she said reflectively. "But I'm so swollen with pride and joy that I could shriek."

That's what it is, partly. A sense of achievement; of conquering the unconquerable; of pitting human wits against giants and winning—a sporting chance. You may climb peaks in a railroad coach and see things as wonderful. But you are doing this thing yourself. Every mile is an achievement. And, after all, it is miraculously easy. The trails are good. The horses are steady and sure-footed. It is a triumph of endurance rather than of courage.

If you have got this far, you are one of us, and you will go on. For the lure of the high places is in your blood. The call of the mountains is a real call. The veneer, after all, is so thin. Throw off the impedimenta of civilization, the telephones, the silly conventions, the lies that pass for truth. Go out to the West. Ride slowly, not to startle the wild things. Throw out your chest and breathe; look across green valleys to wild peaks where mountain sheep stand impassive on the edge of space. Let the summer rains fall on your upturned face and wash away the memory of all that is false and petty and cruel. Then the mountains will get you. You will go back. The call is a real call.

Above the timber-line we rode along bare granite slopes. Erosion had been busy here. The mighty winds that sweep the crests of the Rockies had bared the mountains' breasts. Beside the trails high cairns of stones were piled, so that during the winter snow the rangers might find their way about. Remember, this is northwestern Montana; the Canadian border is only a few miles away, and over these peaks sweeps the full force of the great blizzards of the Northwest.

The rangers keep going all winter. There is much to be done. In the summer it is forest fires and outlaws. In the winter there are no forest fires, but there are poachers after mountain sheep and goats, opium smugglers, bad men from over the Canadian border. Now and then a ranger freezes to death. All summer these intrepid men on their sturdy horses go about armed with revolvers. But in the fall—snow begins early in September, sometimes even in August—they take to snowshoes. With a carbine strung to his shoulders, matches in a waterproof case, snowshoes and a package of food in his pocket, the Glacier Park ranger covers unnumbered miles, patrolling the wildest and most storm-ridden country in America. He travels alone. The imprint of a strange snowshoe on the trail rouses his suspicion. Single-handed he follows the marks in the snow. A blizzard comes. He makes a wikiup of branches, lights a small fire, and plays solitaire until the weather clears. The prey he is stalking cannot advance either. Then one day the snow ceases; the sun comes out. Over the frozen crust his snowshoes slide down great slopes with express speed. Generally he takes his man in. Sometimes the outlaw gets the drop on the ranger first and gets away.
