his arched back loomed before you; now he is utterly gone. It is at this point that some tourists tender their resignations—to take effect immediately. To the credit of the sex, be it said, the statistics show that fewer women quit here than men. But nearly always there is some man who remembers where he left his umbrella or something, and he goes back after it and forgets to return.

In our crowd there was one person who left us here. He was a circular person; about forty per cent of him, I should say, rhymed with jelly. He climbed right down off his mule. He said:

"I'm not scared myself, you understand, but I've just recalled that my wife is a nervous woman. She'd have a fit if she knew I was taking this trip! I love my wife, and for her sake I will not go down this cañon, dearly as I would love to." And with that he headed for the hotel. I wanted to go with him. I wanted to go along with him and comfort him and help him have his chill, and if necessary send a telegram for him to his wife—she was in Pittsburgh—telling her that all was well. But I did not. I kept on. I have been trying to figure out ever since whether this showed courage on my part, or cowardice.

Over the ridge and down the steep declivity beyond goes your mule, slipping a little. He is reared back until his rump almost brushes the trail; he grunts mild protests at every lurching step and grips his shoecalks into the half-frozen path. You reflect that thousands of persons have already done this thing; that thousands of others—men, women and children—are going to do it, and that no serious accident has yet occurred—which is some comfort, but not much. The thought comes to you that, after all, it is a very bright and beautiful world you are leaving behind. You turn your head to give it a long, lingering farewell, and you try to put your mind on something cheerful—such as your life insurance. Then something happens.

The trail, that has been slanting at a downward angle which is a trifle steeper than a ship's ladder, but not quite so steep perhaps as a board fence, takes an abrupt turn to the right. You duck your head and go through a little tunnel in the rock, patterned on the same general design of the needle's eye that is going to give so many of our prominent captains of industry trouble in the hereafter. And as you emerge on the lower side you forget all about your life-insurance papers and freeze to your pommel with both hands, and cram your poor cold feet into the stirrups—even in warm weather they'll be good and cold—and all your vital organs come up in your throat, where you can taste them. If anybody had shot me through the middle just about then he would have inflicted only a flesh wound.

You have come out on a place where the trail clings to the sheer side of the dizziest, deepest chasm in the known world. One of your legs is scraping against the everlasting granite; the other is dangling over half a mile of fresh mountain air. The mule's off hind hoof grates and grinds on the flinty trail, dislodging a fair-sized stone that flops over the verge. You try to look down and see where it is going and find you haven't the nerve to do it—but you can hear it falling from one narrow ledge to another, picking up other boulders as it goes until there must be a fair-sized little avalanche of them cascading down. The sound of their roaring, racketing passage grows fainter and fainter, then dies almost out, and then there rises up to you from those unutterable depths a dull, thuddy little sound—those stones have reached the cellar! Then to you there comes the pleasing reflection that if your mule slipped and you fell off and were dashed to fragments, they would not be large, mussy, irregular fragments, but little teeny-weeny fragments, such as would not bring the blush of modesty to the cheek of the most fastidious.

Only your mule never slips off! It is contrary to a mule's religion and politics, and all his traditions and precedents, to slip off. He may slide a little and stumble once in a while, and he may, with malice aforethought, try to scrape you off against the outjutting shoulders of the trail; but he positively will not slip off. It is not because he is interested in you. A tourist on the cañon's rim a simple tourist is to him and nothing more; but he has no intention of getting himself hurt. Instinct has taught that mule it would be to him a highly painful experience to fall a couple of thousand feet or so and light on a pile of rocks; and therefore, through motives that are purely selfish, he studiously refrains from so doing. When the Prophet of old wrote, "How beautiful upon the mountains are the feet of him," and so on, I judge he had reference to a mule on a narrow trail.

My mule had one very disconcerting way about him—or, rather, about her, for she was of the gentler sex. When she came to a particularly scary spot, which was every minute or so, she would stop dead still. I concurred in that part of it heartily. But then she would face outward and crane her neck over the fathomless void of that bottomless pit, and for a space of moments would gaze steadily downward, with a despondent droop of her fiddle-shaped head and a suicidal gleam in her mournful eyes. It worried me no little; and if I had known, at the time, that she had a German name it would have worried me even more, I guess. But either the time was not ripe for the rash act or else she abhorred the thought of being found dead in the company of a mere tourist, so she did not leap off into space, but restrained herself; and I was very grateful to her for it. It made a bond of sympathy between us.

On you go, winding on down past the red limestone and the yellow limestone and the blue sandstone, which is green generally; past huge bat caves and the big nests of pack-rats, tucked under shelves of Nature's making; past stratified millions of crumbling seashells that tell to geologists the tale of the salt-water ocean that once on a time, when the world was young and callow, filled this hole brim full; and presently, when you have begun to piece together the tattered fringes of your nerves, you realize that the cañon is even more wonderful when viewed from within than it is when viewed from without. Also, you begin to notice now that it is most extensively autographed.

Apparently about every other person who came this way remarked to himself that this cañon was practically completed and only needed his signature as collaborator to round it out—so he signed it and after that it was a finished job. Some of them brought down colored chalk and stencils, and marking pots, and paints and brushes, and cold chisels to work with, which must have been a lot of trouble, but was worth it—it does add so greatly to the beauty of the Grand Cañon to find it spangled over with such names as you could hear paged in almost any dollar-a-day American-plan hotel. The guide pointed out a spot where one of these inspired authors climbed high up the face of a white cliff and, clinging there, carved out in letters a foot long his name; and it was one of those names that, inscribed upon a register, would instinctively cause any room clerk to reach for the key to an inside one, without bath. I regret to state that nothing happened to this person. He got down safe and sound; it was a great pity, too.

By the Bright Angel Trail it is three hours on a mule to the plateau, where there are green summery things growing even in midwinter, and where the temperature is almost sultry; and it is an hour or so more to the riverbed, down at the very bottom. When you
