"I must be, too," thought Ned, steeling himself. As he did so, the alarming downward motion ceased. They began to rise once more, swinging upward and climbing the sky in long, lazy circles.
It was then and there that Ned's attack of air fever left him, never to return. Compared to the experiences of his companions, he learned later he had had a comparatively mild attack.
Ned now began to look about him. The other two aeroplanes were soaring below them, like big birds of the buzzard kind. He felt a wild desire suddenly gripping his heart to go higher--right up among the fleecy clouds that hung above them. Perhaps the officer read his thoughts. At any rate, they continued to climb the aerial staircase. At a height of four thousand feet, they plunged into a fog. The sudden change from the bright sunlight was bewildering.
"We are passing through one of those clouds that you saw from below," volunteered the officer. He glanced at the barograph and read off to Ned the height to which they had arisen.
"Good gracious," thought the lad, "four thousand feet above the earth, and nothing between me and it but the soles of my shoes!"
But Ned's terror had gone. He began to take a real interest in the operation of the aeroplane now. It was fascinating to a degree. All at once they emerged from the wet fog bank and glided into the sunlight. Condensed moisture covered the planes. Drops of water, turned to miniature rainbows by the sunlight, slid down the wire stays and supports.
"Want to go higher?" asked the officer presently.
"We might as well. You are standing it splendidly, Strong."
Ned felt himself glow with pleasure. Words of praise from an officer are not plentiful in our or any other navy. But, as we have seen, the discipline on the aviation squad was not exactly as rigid as on board a battleship.
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.
