"Goodbye old land!" sang out Andy, when they seemed to suddenly pass out over the water, leaving the shore of New York behind.
Frank said not a word, but no doubt his feelings were just as strong as those of his companion. And so they had now embarked on what seemed to be the last leg of the strange chase, with the future lying before them as mystifying as that fog bank lying far away to the north.
CHAPTER XXI
OVER THE BOUNDARY LINE
It was with the queerest possible feeling that Andy saw the land slipping away, and realized that they were at last launched upon the water part of the voyage.
It seemed as though they had cast loose from their safe moorings, and were adrift upon an uncharted sea. When comparing his feelings with other aviators in later times, he learned that every one of them had experienced exactly similar sensations the first time they passed out of touch of land, and found the heaving sea alone beneath them. It was a sort of air intoxication; Andy even called it sea-sickness, though doubtless most of it came from imagination alone.
"There they go, Frank!" he called out, not ten minutes later.
The land was far behind them now, and still in the other three directions they saw only the level surface of the great lake.
