The sight was a powerful argument, worth more than all the words that could have been spoken.

The Indians sullenly returned to their fire and sat down, while our friends, casting many watchful glances over their shoulders as they went, made good their retreat in the direction of their own camp.

"What kind of Indians were they?" asked Glen, of the Mexican, when they had lost sight of their unpleasant acquaintances.

"Navajos," was the answer.

They were indeed a wretched band of the once wealthy and powerful tribe who claimed that whole country as a pasture-land for their countless flocks and herds. For many years they had been hunted and killed, their flocks driven off and their growing crops destroyed wherever found, until now the main body of the tribe was being slowly starved out of existence on a small reservation in Eastern New Mexico. It was so small that no more Indians could be crowded into it, and the miserable remnant, who still lurked in the fastnesses of their own country, despoiled of all means of procuring a livelihood, prowled about like so many hungry dogs, gleaning the offal from white men's camps, and hunted like wild beasts by all whom they were unfortunate enough to meet.

This band had probably followed Mr. Hobart's party for the sake of what might be picked up in their abandoned camps, and had evidently regarded the poisoned meat, discovered that very morning, as a perfect godsend.

"I reckon we'll have to manage somehow to get along without any wolves," said "Billy" Brackett.

"Yes," replied Glen, regretfully, "I suppose we shall."

Ten miles of line were run that day, through the solemn pine forest, and darkness overtook the party on the very summit of the great Continental Divide. They were crossing the Sierra Madre Mountains, through Zuñi Pass. As Glen subtracted the last reading of his rod for the day from the last height of instrument, and found that it gave an elevation of 7925 feet, he uttered a shout. For weeks the elevations above sea-level had been steadily mounting upward. This one was a foot lower than the last.

"Hurrah!" he cried, "we are on the Pacific Slope."
