Already it was growing difficult to distinguish objects in some of the canyons and defiles over which they sailed, indicating that they might be missing something of value. Accordingly Jack swung abruptly around and rising like an eagle on the wing, started to go back.

He could see that Suzanne noticed this abrupt change in their course for she displayed some uneasiness. He motioned to Perk to let her have the earphones again and proceeded to explain just what must be done.

At first the girl was distressed, for to her mind it looked as though her staunch friends might be growing weary of their hopeless quest and meant to abandon it altogether, but as Jack carefully explained why it was necessary they should land for the night while the opportunity offered and that nothing would be sacrificed in so doing, Suzanne began to comprehend and nod her head in approval.

“We can stop over and get rested up instead of keeping on this gruelling task without the slightest chance for accomplishing anything,” he told her finally, though immediately adding: “that covers the night only, for as soon as morning comes we shall start out, fixed to keep going all day long.”

“I understand just what you mean, Jack, and I don’t know how to thank you both for all you are doing for me—for Buddy—for Ma Warner, waiting there at home and hardly sleeping a wink as she thinks and thinks and prays her boy may be given back to her safe and sound.”

Jack did not say any more, he could not because by now his own hopes were diminishing at a rapid rate. Was it any wonder that such should be the case when three full days had now crept along since the air-mail pilot vanished into the realms of space, and never a single word coming back to explain his fate?

For the sake of this brave girl, so ready to risk her own life in the service of the one she loved, he must try to keep up a confident front. If it was ordained that she too must see her hopes crushed, at least he and Perk would have the satisfaction of knowing they had done everything in their power to bring her great joy. So too, that anxious mother in the far away home, what gratification it would give them if they could dry her tears and be helpful in bringing her boy back to her arms.

They were now nearing the valley where the little way-station on the air-mail route lay between its majestic sentinel snow-clad peaks. Jack meant to circle twice at least, so as to get a good idea as to how the ground lay for by now daylight would be giving place to dusk in that valley, and visibility not all they could wish, so it would pay them to be very careful.

Jack could see that Suzanne was greatly interested and he knew just why. Here at this mountain station, Buddy was in the habit of landing every time his flight took him back and forth. Doubtless he had made friends with some of the town folks, especially those connected with the flying field for his was a nature that always attracted people. It agitated her to realize that she might even hear him spoken of in the highest terms, and what pride such a thing must stir up in her young heart!

Jack was circling the field and constantly dropping lower with each round so that he had already been able to pick out the exact spot where he meant to land.
