"Yes. United States cavalry. There are several companies stationed out here, and they may be on a practice march, or having a sham battle, as they sometimes do. These are signals from one post to another."

"Or maybe a signal about the Indians," suggested Bud.

"Yes," agreed Snake. "It may be the troopers are after the Yaquis. I sure hope so, for the imps are going to be hard enough to nab once they get up in the foothills and mountains. We'll need the help of the troopers for sure!"

"Isn't there some way we could let them know we're coming?" asked Dick.

"Not very handy," the cowboy leader answered. "We haven't any fireworks, and shooting off our guns would only waste good bullets that we may need later. Besides, those shooting stars are farther off than they look. We couldn't make our guns heard, and the flashes would be so low down they couldn't be seen. All we can do is to wait until morning. We're traveling in that direction anyhow, and we may come up with the regulars."

"With their help we'll make short work of the Yaquis!" boasted Nort.

"Don't be so sure of that," warned Rolling Stone. "The Indians, while nothing like the American redmen, are cute and foxy enough in their own way. They probably know of nooks and hiding places in the mountains where they could lay up for weeks, and almost next door to a troop of soldiers, without getting located. It's going to be largely a matter of luck if we nab 'em!"

"Well, here's hoping," voiced Bud, as he turned toward the fire.

It was chilly out in the open at that hour of the morning. For though the days are very hot, it began to get cool very often as soon as the sun went down, and the air kept getting cooler until the golden rays again warmed the earth. So one and all sought the genial blaze, to thaw out a little before again rolling in blankets to wait for sunrise.

Aside from the alarm over the shooting stars, nothing else disturbed the camp that night, and all were gladly astir with daybreak. The fire was started into new life, and soon coffee was boiling over the coals, while mingled with its odor was the appetizing smell of crisp bacon.
