A dull red spot glowed in each of Dave's tanned cheeks. With a quick intaking of his breath he lightly touched the spurs to his horse—lightly, for that was all the intelligent beast needed. Dave passed his taunting enemy on the rush, and planting himself directly in front of him on the trail, drew rein so sharply that his steed reared. The cows, scattered by the sudden rush, ambled awkwardly on a little distance, and then stopped to graze.

"What do you mean by getting in my way?" growled Len.

"I mean to have you stop and answer a few questions," was the calm retort.

"If it's about these cattle I tell you I'm not trying to drive off any of yours," said Len, in whining tones. He knew the severe penalty attached to this in a cow country, and Dave was sufficiently formidable, as he sat easily on his horse facing the bully, to make Len a little more respectful.

"I'm not going to ask you about these cattle—at least not right away," Dave went on. "This is about another matter. You said something just now that needs explaining."

"I say a good many things," Len admitted, and again there sounded in his voice a sneer. "I don't have to explain to you everything I say; do I?"

"You do when it concerns me," and Dave put his horse directly across the trail, which, at this point narrowed and ran between two low ranges of hills. "You said something about me just now—you called me a nameless, picked-up nobody!"

Dave could not help wincing as he repeated the slur.

"Well, what if I did?" demanded the bully.

"I want to know what you mean. You insinuated that Mr. Carson was not my father."
