“They must have gone to the Moon!” Gran’ma cried. “No, they must have changed their course!” she added after a moment as the Flying Boat, following the course taken by the children, made the circuit of the Moon.

But the Flying Boat soon flew directly at the Moon and the old folks knew the children must have made a landing there.

“Here we are!” Gran’pa cried, as he helped Gran’ma from the Flying Boat. “See where they have been sitting in the grass!”

“Oh! Maybe wild beasts have eaten them up!” cried Gran’ma.

“No! There are no signs of wild beasts!” Gran’pa replied. “We should see their torn clothes about if that were the case! See, their trail leads off this way!”
