"Oh! I own up you fellows have kind of excited me a little when telling about that thrilling sound you heard," he admitted candidly. "I'd like first-rate to do some prowling around up there to satisfy myself that it wasn't a peacock that screamed, or even a tied-up dog that yelped."

"But I hope you'll give over that idea then, Jerry," said Frank soberly. "You must understand that Mr. Dennison is a gentleman, for all he looks so queer and acts so strangely. He's had something upset him in the past, and chooses to live away from everybody."

"Yes," added Will, "and he's got a right to do as he chooses with his own property, you'll allow, Jerry."

"Sure thing!" agreed the other, though with a shade of disappointment crossing his face, "and I guess I'll have to keep my hands off, since the sign is up 'no trespassing allowed here!' But anyway, I do hope we shall run across Old Aaron and his Rod somewhere in our jaunt to-day."

Frank had nothing more to say on the subject. He was determined not to yield to any temptation, and enter those forbidden grounds again after being so plainly warned off by the irascible owner.

Leaving the rocky section of country, they began to traverse a region quite different in its character. From time to time various interesting things cropped up to attract their attention.

Bluff and Jerry wanted the photographer to snap off all sorts of what they called "mighty absorbing subjects," but Will wisely used his fine discrimination.

"Why, look here," he finally told them, "if I took your advice right along I'd be out of stock in the film line before half the day was over. And I don't know of anything to make a fellow feel worse than to have used his last film and then run across a subject that he'd give heaps to get."

"Will is right, boys," remarked Frank; "leave it to him to decide things like that. I'd stake a lot on his judgment, you must know."

"Well," commented Will, with a chuckle, "I'm a ninny when it comes to lots of things connected with outdoor life; but I do know something about taking pictures, if I say it myself."
