But presently Ned's pleasant glow gave way to a shivering sensation. It was growing bitterly cold. His teeth chattered and his hands turned a beautiful plum color. The moisture from the cloud began to freeze on the machine.

"Enough for to-day," decided the officer, and he started to descend.

The drop was rapid, yet now that Ned was more used to it, he felt no particular alarm. In an incredibly short time, so it seemed, the earth rushed up to meet them, and they landed on the aviation field as lightly as a wind-wafted feather.

The next day Ned and the two other most proficient pupils—Merritt and Chance—were given a chance to handle the levers alone. They acquitted themselves well. Their advancement proved rapid, living up to the promise of their first efforts. On the day which we described at the beginning of this chapter, Ned, as we have seen, was capable of handling an aeroplane alone. So were Merritt and Chance. Herc was a fair airman, and the others were progressing favorably.

But the real rivals of the air were, at present, Ned, Merritt and Chance.
