I came into a tree top to watch them.

According to legend, the tree top is said to shine at times of emergency.

The tree tops weren't more than a hundred feet down.

Through them were tree tops, and a patch of blue sky.

He stopped for a moment, looking up at the tree tops.

Couldn't they get some fresh green - even tree tops?

"We'll just have to set down in the tree tops," he said.

"You know those tree tops may be a couple of hundred feet from the ground, or even more?"

He held his position just over the tree tops and roared on.
