Ballooning

In Ballooning, some inhabitants of Mammoth Island decide to explore the far side of a distant mountain ridge on a breezy spring day. Half way up the steep mountain trail, their trusty mammoth becomes afraid and winds up trapped on the mountainside.

Their plan involves using the balloon to float back up the mountain, where they harness the mammoth and carry him safely back to the village. Part of the multivolume series The Way Things Work.
