"How far does the Navahoe country come this way?"
"There ain't no fence, Tom, I expect. They reckon as it's their country just as far as they like to come. They don't come up as far north as this, but where they ends and where the Utes begin no one knows but themselves; and I reckon it shifts according as the Navahoes are busy with the Mexicans in the south, or have got a quiet spell, and take it into their heads to hunt this way."
For many days they continued their journey, sometimes floating quietly along a comparatively wide valley, sometimes carrying their boats past dangerous rapids, sometimes rushing along at great speed on the black, deep water, occasionally meeting with falls where everything had to be taken out of the canoes, and the boats themselves allowed to shoot over the falls with long ropes attached, by which they were drawn to shore lower down. It was seldom that they were without meat, as several big-horns and two bears were shot by the Indians. They had no doubt that they could have caught fish, but as a rule they were too tired when they arrived at their halting-place to do more than cook and eat their suppers before they lay down to rest.
"I reckon it won't be very long before we come upon a Mexican village," Harry said one day, after they had been six weeks on their downward course. "I have heard there is one above the Grand Cañon."
The scenery had varied greatly. In some of the valleys groves of trees bordered the river; sometimes not even a tuft of grass was to be seen. Occasionally the cliffs ran in an even line for many miles, showing that the country beyond was a level plateau, at other times rugged peaks and pinnacles resembling ruined castles, lighthouses, and churches could be seen. Frequently the cliffs rose three or four thousand feet in an almost unbroken line, but more often there were rounded terraces, where it would have been easy to ascend to the upper level. Everywhere the various strata were of different colours: soft grays and browns, orange, vermilion, purple, green, and yellow. They soon learned that when they passed through soft strata, the river ran quietly; where the rocks were hard there were falls and rapids; where the strata lay horizontal the stream ran smoothly, though often with great rapidity; where they dipped up stream there were dangerous rapids and falls.
