Joe’s honest eyes narrowed to steely slits and his lips tightened into a grim line.

“The Double O had always been a tough outfit, but I never figured old man Anderson would stand for murder. If we find one of their riders is riding a horse with a shoe like that, watch out for trouble in great big chunks.”

The Box B riders remounted and started north into the Double O territory. From the trail, it was evident that the cattle had been driven hard, but the small herd had been fairly easy to handle.

They penetrated more than a mile into the Double O range when a group of riders galloped into sight over a low hill.

“Here comes trouble,” grinned Chuck, loosening his rifle and making sure that it was ready for fast action. The other Box B riders looked at their guns and Slim’s heart tightened. Tempers were at a fighting pitch. It would require some real diplomacy to get through the next few minutes without someone being hurt, perhaps seriously.

The two groups of riders swept toward each other at a furious pace, slowing down only when they were less than two hundred yards apart. At a hundred yards they stopped, eyeing each other warily, waiting for the first break.

“Old man Anderson’s with his boys and he’s wearing two guns,” said Joe. “That means he’s on the warpath sure.”

Slim counted the Double O riders. Five men were ranged behind their boss and he recognized one of them as Al Bass, the range rider they had seen the day before.

“They’ve got our cattle,” said Walt Kelly impatiently. “What are we going to do, talk or shoot?”

“We’ll talk first,” said Joe, curbing his first impulse to shoot it out, for the Box B was outnumbered.
