Luckily they were able to land in a large clearing, many miles from where the Indians had attacked them, and, as they were now over the Canadian border—a fact ascertained by seeing some boundary pillars as they crossed—they had no further fear of the Blackfeet.

“But it was a hot time while it lasted,” said Bob, who explained how the attack had come about.

Breakfast was served, and then the motor boys proceeded to finish work on the rudder. Professor Snodgrass, who had taken no part in the repulse of the Indians, save to gather his books and specimen boxes in readiness for instant flight, resumed his collecting.

The two Westerners devoted themselves to making a tour of the surrounding country, to look for possible hostile signs, but found none. Then they managed to get some small game for Bob to cook.

The rudder repairs were finished that day, and a test of the Comet showed it to be under perfect control.

“Now for the valley of the sixty nuggets of gold!” cried Jerry, when they were ready to start off again.

For two days they circled about, looking for some landmark that would indicate to Mr. Brill the beginning of the big earth gash where he had hidden his wealth. They saw, one evening, a fantastically piled mound of red rock that showed plainly even from a great height.

“There it is!” cried the prospector. “The valley begins right there!”

“Then we’ll go down, and camp for to-night,” decided Jerry, “and in the morning we’ll make the descent.”

The morning dawned, clear and beautiful. After an early breakfast they went aloft in the Comet, which could now be guided better than ever.
