"Probably you're right, but, for goodness sake, be careful."

"Surest thing you know."

"What's the Owl's Head?" Jack asked.

"Why, it's a big rock up in the hills and it's shaped almost exactly like the head of an owl. It's really worth seeing. You aren't afraid, are you?" she asked.

Of course, both boys quickly assured her that they were not in the least frightened and she hurried to the kitchen to see about the lunch. They started an hour later shortly before nine o'clock. It was a beautiful cool morning, although a haze in the air prevented them from being able to see more than an indistinct outline of the hill some ten miles away.

"We'd better take it easy," Sue cautioned them as they rode out of the yard. "It's pretty hard climbing once we get to the hills and we want the horses fresh when we start on it."

She struck off at an easy lope, which any one of the horses could maintain all day, and they followed close behind. They had ridden for a little over an hour when she suddenly drew rein and stopped.

"Can you see anything that looks like a man over there?" she asked pointing in the direction they had had been going.

"There seems to be something moving there," Bob replied, shading his eyes. "How about it, Jack?"

"I see it, but it's too far away to tell what it is."
