The long journey across the Western States (by the Santa Fe route) was full of interest at every point. Even the monotony of the Middle West was not wearisome, while the scenery and scenes in New Mexico and Arizona were fascinating in the extreme.

Mr. Burroughs had been to the Far West by a northern route, but this was all fresh territory to him, and he brought to it his usual keen appetite for new phases of nature, made still keener by a recently awakened interest in geological subjects. It enhanced the pleasure and profit of the trip a hundredfold to get his first impressions of the moving panorama, as I did when he dictated notes to me from his diary, or descriptive letters to his wife and son. The impression one gets out there of earth sculpture in process is one of the chief attractions of the region, and Mr. Burroughs never tired of studying the physiognomy of the land, and the overwhelming evidences of time and change, and of contrasting these with our still older, maturer landscapes in the East.

In passing through Kansas he commented on the monotonous level expanse of country as being unbearable from any point of view except as good farm land. Used to hills and mountains, inviting brooks and winding roads, he turned away from this unpicturesque land, saying if it was a good place to make money, it was also a place to lose one's own soul—he was already homesick for the beauty and diversity of our more winsome country.

Two days' journey from Chicago and we reached the desert town of Adamana. As the train stopped near the little inn, a voice called out in the darkness, "Hello, Johnnie, is that you?"

"Yes, John Muir"; and there under the big dipper, on the great Arizona desert, the two friends met after a lapse of ten years.

"Muir, aren't you surprised to find me with two women in my wake?" asked Mr. Burroughs, introducing us.

"Yes; surprised that there are only two, Johnnie." Then to us, "Up in Alaska there were a dozen or two following him around, tucking him up in steamer rugs, putting pillows to his head, running to him with a flower, or a description of a bird—Oh, two is a very moderate number, Johnnie, but we'll manage to worry through with them, somehow." And picking up part of our luggage, the tall, grizzly Scot led the way to the inn.

The next day we drove nine miles over the rolling desert to visit one of the petrified forests, of which there are five in that vicinity. Blended with the unwonted scenes—the gray sands dotted with sagebrush and greasewood, the leaping jack rabbits, the frightened bands of half-wild horses, the distant buttes and mesas, and the brilliant blue of the Arizona sky—is the memory of that talk of Mr. Muir's during the long drive, a talk which for range and raciness I have never heard equaled. He often uses the broad dialect of the Scot, translating as he goes along. His forte is in monologue. He is a most engaging talker,—discursive, grave and gay,—mingling thrilling adventures, side-splitting anecdotes, choice quotations, apt characterizations, scientific data, enthusiastic descriptions, sarcastic comments, scornful denunciations, inimitable mimicry.

Mr. Burroughs, on the contrary, is not a ready talker; he gives of his best in his books. He establishes intimate relations with his reader, Mr. Muir with his listener. He is more fond of an interchange of ideas than is Mr. Muir; is not the least inclined to banter or to get the better of one; is so averse to witnessing discomfiture that even when forced into an argument, he is loath to push it to the bitter end. Yet when he does engage in argument, he drives things home with very telling force, especially when writing on debatable points.

As we drove along the desert, Mr. Muir pointed to a lofty plateau toward which we were tending,—"Robbers' Roost,"—where sheep-stealers hie themselves, commanding the view for hundreds of miles in every direction. I wish I could make vivid the panorama we saw from this vantage-ground—the desert in the foreground, and far away against the sky the curiously carved pink and purple and lilac mountains, while immediately below us lay the dry river-bed over which a gaunt raven flew and croaked ominously, and a little beyond rose the various buttes, mauve and terra-cotta colored, from whose sides and at whose bases projected the petrified trees. There lay the giant trees, straight and tapering—no branching as in our trees of to-day. The trunks are often flattened, as though they had been under great pressure, often the very bark seemed to be on them (though it was petrified bark), and on some we saw marks of insect tracery like those made by the borers of to-day. Some of the trunks were more than one hundred and fifty feet long, and five to seven feet in diameter, prostrate but intact, looking as though uprooted where they lay. Others were broken at regular intervals, as though sawed into stove lengths. In places the ground looks like a chip-yard, the chips dry and white as though bleached by the sun. The eye is deceived; chips these surely are, you think, but the ear corrects this impression, for as your feet strike the fragments, the clinking sound proves that they are stone. In some of the other forests, visited later, the chips and larger fragments, and the interior of the trunks, are gorgeously colored, so that we walked on a natural mosaic of jasper, chalcedony, onyx, and agate. In many fragments the cell-structure of the wood is still visible, but in others nature has carried the process further, and crystallization has transformed the wood of these old, old trees into the brilliant fragments we can have for the carrying—"beautiful wood replaced by beautiful stone," as Mr. Muir was fond of saying.
