A Texas Ranger
The Texan looked down at the ruffian under his feet.
"Do you know the road to Mexico by the Arivaca cut-off?"
"Then climb into my rig and hit the trail hard-- burn it up till you've crossed the line."
The fellow began to whine thanks, but the man above would have none of them, "I'm giving you this chance for your sister's sake. You won't make anything of it. You're born for meanness and deviltry. I know your kind from El Paso to Dawson. But she's game and she's white clear through, even if she is your sister and a plumb little fool. Can you walk to the road?" he ended abruptly.
"I think so. It's in my ankle. Some hell-hound gave it me while we were getting over the wall," the fellow growled.
"Don't blame him. His intentions were good. He meant to blow out your brains."
The convict cursed vilely, but in the midst of his impotent rage the other stopped and dragged him to his feet.
