“What for? He may be out there waiting for you.”

“Let him. If he is I’ll dive for the clouds again. If he is not there and we have lost him, then all the better. We want to be as close to the cave as possible.”

William timed himself. After seven or eight minutes of flying he called out, “I’m getting out of the clouds.”

And the next instant they dived. Out in the open again, both boys looked everywhere for the enemy plane but there wasn’t a speck in sight. Both boys heaved a sigh of relief and smiled at each other. “You did it this time,” asserted Jack.

“There’s the clearing,” announced William and pointed.

“That’s right. Are you going to land now?”

“I’ll first circle the field a couple of times.”

He proceeded to do so. Some moments later, William cried, “Look they are waving.”
