"It's the black cat," muttered the fat boy. "And we'll all be lame ducks in a minute."

"Keep steady, lads," warned the Professor in a low tone.

Tad nodded, taking in his fellows in the same nod as indicating that they were to take no action until ordered to do so.

"Professor, I'm going on," announced Butler. "We may stand here all day arguing at the present rate."

With that Tad clucked to his pony and started, picking his way through the growth in the open space.

"You stop where you are!" commanded the mountaineer.

"You stop me if you dare," retorted the Pony Rider Boy. "Come along, Professor."

Instead the Professor sat grimly in his saddle, eyeing the mountaineer sternly. The latter half raised his rifle, bringing the muzzle to bear on the advancing Tad.

"Oh, fudge! Put that gun back in your boot!" scoffed Butler. "You know you don't dare to use it. You know very well that you would get the worst of it if you dared to pull the trigger."

"Are you going back?" roared the mountaineer.
