From below came the sound of voices. The “Ogden II” was being hauled from under its tent and made ready for a flight in record time.

Suddenly Tim’s head appeared above the trap-door.

“Great Scott! Didn’t think I’d see it so close as all that,” he said, climbing up. “Isn’t it a great sight, eh? Give me a chance at that, Cranny.”

The observer was exhibiting unmistakable signs of excitement.

“Yes, sir; as I live, it’s true!” he cried.

“What do you mean?” asked Tim, excitedly.

“Well, well! If it isn’t a fact, just let me know.”

Cranny, with a look expressive of the greatest astonishment, stepped aside, while Dick took his place.

By this time the “Border City,” flying high, was almost abreast of Lone Pine.

As Dick Travers looked through the telescope, every detail of the great air-ship flashed into view with wonderful distinctness.
