With what wonder and incredulity we roamed about witnessing the strange spectacle!—the prostrate monarchs with hearts of jasper and chalcedony, now silent and rigid in this desolate region where they basked in the sunlight and swayed in the winds millions of years ago. Only a small part of the old forest is as yet exposed; these trees, buried for ages beneath the early seas, becoming petrified as they lay, are, after ages more, gradually being unearthed as the softer parts of the soil covering them wears away.

The scenic aspects of the place, the powerful appeal it made to the imagination, the evidences of infinite time, the wonderful metamorphosis from vegetable life to these petrified remains which copy so faithfully the form and structure of the living trees, were powerfully enhanced by the sight of these two men wandering amid these ruins of Carboniferous time, sometimes in earnest conversation, oftener in silence; again in serious question from the one and perhaps bantering answer from the other; for although Mr. Burroughs was intensely interested in this spectacle, and full of cogitations and questions as to the cause and explanation of it all, Mr. Muir was not disposed to treat questions seriously.

"Oh, get a primer of geology, Johnnie," he would say when the earnest Eastern student would ask for a solution of some of the puzzles arising in his mind—a perversity that was especially annoying, since the Scot had carefully explored these regions, and was doubtless well equipped to adduce reasonable explanations had he been so minded. That very forest to which we went on that first day, and where we ate our luncheon from the trunk of a great petrified Sigillaria, had been discovered by Mr. Muir and his daughter a few years before as they were riding over the sandy plateau. He told us how excited he was that night—he could not sleep, but lay awake trying to restore the living forest in imagination, for, from the petrified remains, he could tell to what order these giants belonged.

When others congregate to eat, the Scot seems specially impelled to talk. With a fine disregard for food, he sat and crumbled dry bread, occasionally putting a bit in his mouth, talking while the eating was going on. He is likewise independent of sleep. "Sleep!" he would exclaim, when the rest of us, after a long day of sight-seeing, would have to yield to our sense of fatigue, "why, you can sleep when you get back home, or, at least, in the grave."

Mr. Burroughs, on the contrary, is specially dependent upon sleep and food in order to do his work or to enjoy anything. On our arrival at the Grand Canon in the morning, after a night of travel and fasting, all the rest of us felt the need of refreshing ourselves and taking breakfast before we would even take a peep at the great rose-purple abyss out there a few steps from the hotel, but the teasing Scot jeered at us for thinking of eating when there was that sublime spectacle to be seen. When we did go out to the rim, Mr. Muir preceded us, and, as we approached, waved toward the great abyss and said: "There! Empty your heads of all vanity, and look!" And we did look, overwhelmed by what must be the most truly sublime spectacle this earth has to offer—a veritable terrestrial Book of Revelation, as Mr. Burroughs said.

We followed a little path along the rim, led by Mr. Muir, to where we could escape from the other sight-seers, and there we sat on the rocks, though the snow lay in patches on the ground that bright February day. Mr. Burroughs made a fire of Juniper brush, and as the fragrant incense rose on the air, with that wondrous spectacle before our eyes, we listened to Mr. Muir reciting some lines from Milton—almost the only poet one would think of quoting in the presence of such solemn, awful beauty.

Mr. Muir tried to dissuade us the next day from going down into the canon: "Don't straddle a mule and poke your noses down to the ground, and plunge down that dangerous icy trail, imagining, because you get a few shivers down your backs, you are seeing the glories of the canon, or getting any conception of the noble river that made it. You must climb, climb, to see the glories, always." But when Mr. Burroughs would ask him where we could climb to, to see the canon, since under his guidance we had been brought to the very edge on the top, he did not deign to explain, but continued to deride the project of the descent into the depths—a way the dear man has of meeting an argument that is a bit annoying at times.

We did go down into the canon on mule-back,—down, down, over four thousand feet,—and the jeering Scot went with us, sitting his mule uncompromisingly, and indulging in many a jest at the expense of the terrified women who felt, when too late to retreat, that it would have been better to heed his advice. Still, after the descent, and then the ascent, were safely accomplished, we were glad we had not let him dissuade us. None of us can ever forget that day, with its rich and varied experiences, the mingled fear and awe and exultation, the overpowering emotions felt at each new revelation of the stupendous spectacle, often relieved by the lively sallies of Mr. Muir. We ate our luncheon on the old Cambrian plateau, the mighty Colorado, still a thousand feet below us, looking entirely inadequate to have accomplished the tremendous results we were witnessing.

One day at the canon, feeling acutely aware of our incalculable privilege, I said, "To think of having the Grand Canon, and John Burroughs and John Muir thrown in!"

"I wish Muir was thrown in, sometimes," retorted Mr. Burroughs, with a twinkle in his eye, "when he gets between me and the canon."
