The affairs of young Deane had been adjusted with supreme satisfaction for our hero. It warmed his loyal heart to think that through the unselfish efforts of the crew of the Comet, the brother of Edna Deane was now speeding safely and comfortably on his way to those who had mourned him.

The trader friend of Adrianoffski had done everything in his power to make sure the homeward journey of the fugitive. The young airman had insisted on paying him liberally for his cooperation. He had arranged so that Morris Deane could be provided with money current in the different countries through which he must pass. The trader was to convey Deane out of Thibet concealed in a cart carrying merchandise. He was to be provided with a disguise. Until he passed the Russian frontier and was placed upon a train bound for St. Petersburg, two trusty agents were to accompany and protect him.

The boys felt happy over all this. They had lost little time and gained some experience in doing a humane act. Then the regular schedule of progress was resumed. Now, as noted, Hiram had put a startling question. The pilot of the Comet had responded with an ominous assertion.

When Hiram had asked: “What was that?” a sudden glare in the distance followed by a harsh, detonating crash had caused his sudden query.

Our hero had explained that it was “War.” He intimated further that this was a possible menace to their expedition, in that they might not retrace the route they had come.

“I hoped to keep out of the Turkish trouble,” proceeded the young airman; “but we must take the edge of it, I fear. You know we passed over a great military camp just before dusk.”

“Yes, and they sent a brisk volley after us,” reminded Hiram.

“Without calculating the way the Comet can fly,” added Elmer, with a chuckle.

“We had better keep at a pretty high level just the same,” observed Dave. “I will be glad when we get out of these intricate mountain ranges. Then we can see what is ahead of us and get our bearings.”

Just then another explosion sounded. It was mingled with a series of minor reports, echoing from past the ridge of hills to the East.
