They sprang into a wagon and prepared to follow the direction of the balloon, supposing it would come down as soon as the hot air began to cool off.

Meanwhile, what of Leo?

So sudden was the upward rush of the balloon that the boy was thrown to the bottom of the basket ere he was aware.

He clutched the sides and then ventured to look down. The earth seemed to be fading away beneath him.

For a few minutes he was deadly sick at the stomach and there was a strange ringing in his ears.

The balloon was moving in the direction of Hopsville. Soon it passed over the town.

Leo could see the few streets and the brook laid out like a map beneath him.

He was growing accustomed to his novel situation.

On and on went the balloon.

The wind appeared to blow stronger the higher he went.
