Perhaps that was the reason I found myself tramping down the long, steep trail. The more photographs I took, the further down I went to take another. One view followed another with endless change. At every turn there was some new sensation, some fresh vista that just cried out for remembrance. In this way I gradually found myself descending into the depths of the Canyon. Truly it is the most wonderful walk I have ever had.

It was as though the traveller were entering a new world of a new climate, new scenery, and new sensations. Up on the plateau at the top the altitude was 8,000 feet above sea level, and the heat there had been intense. But as I descended thousand after thousand of feet into the bowels of the earth, the air became more dense and the heat more intense until at the bottom, over 6,000 feet below, the climate was almost tropical. Further, the great "temples"—the fragments of the plateau where the erosion had left isolated mountains remaining within the gorge—took on a far different aspect when viewed from below. From above one saw them as one would see hills and valleys from an aeroplane—with hardly any relief. But from below they loomed up sharp against the sky, each one a mighty mountain in itself. What seemed from the brink to be a mere blotch of green mould on the bare rocks below proved on closer acquaintance to be a luxurious coppice, dense with trees and shrubs and tall, thick grass. Minute specks of black scattered broadcast on the slope turned out to be trees that eked out a scanty but sufficient livelihood on the crevices and the crags. A brown, inconspicuous carpet from above developed into a huge tropical plateau several miles across. So clear is the atmosphere and so great are the distances that magnitudes are ridiculed and illusions raised to the point of absurdity.

It was well after midday when I reached the bottom and watched the roaring, rushing Colorado, like a great yellow flood, lashing its angry way between the steep walls of the granite gorge. Above, it had been invisible, unknown, and whisperless.

The walk back developed into a tiring, eternal struggle up an interminable staircase that had no stairs. Sometimes I half decided to rest until next day. At intervals I grasped my knees in my hands and helped to lift the heavy, tired feet one above the other. I abused myself heartily for not having furnished myself with reserve refreshments before starting, and then remembered that I had only set out to take a few pictures; I had quenched my thirst at a little creek six hours before, but felt that a meal of some kind would be acceptable.

I arrived at the top about 5.30. The mule-party had overtaken me a quarter of an hour before. They had only stopped half an hour at the bottom for lunch.

"Waal, I've done some walkin' in my time, boss, but I guess you've gotten the best pair o' legs that ever MY optics did see," was the remark of one heavily-spectacled American who beamed from his mule upon me as he passed.

"Aye, that's so," echoed others in the long file with undisguised approbation.

So the reader will observe that I am already becoming Americanized, even in true modesty!
