“You boys know that Gordon—if you see him don’t take no chances. I’m gettin’ a gang together, and we’ll follow pronto—fast as the automobile can bring us.”

“We could take you along now,” Kramer suggested.

“I can’t leave the office for half an hour. Got something needs my attention here and it’s almost as important as gettin’ Gordon. Do you swear to do your duty as officers of the law and upholders of the Constitution of the United States? That ain’t real regular, but you know what it means.”

“I do,” came from three throats. Then they climbed into the cock-pits.

PIGEON JUTE

“Hit her up, loop the sun,” Bob called as he climbed into the rear cock-pit. Kramer let the motor run for a moment, then managed to smile at her performance.

“That’s a motor what motes,” he announced. Soon they took off and they looked most war-like with the sheriff’s artillery added to their equipment. Through the minds of the Sky Buddies raced a varied assortment of possibilities regarding what they would find when they came down on the Gordon ranch. Jim rather wished that Bob was not along for if either young Arthur or any of his former associates were there no one would anticipate how much trouble awaited them. Although there was only a few months difference in their ages, Austin felt years older and was anxious that the younger boy be kept out of danger. He recalled the scheme the two Gordons had concocted and nearly brought to perfection at Don Haurea’s ranch a few months ago. While Caldwell had not been hurt physically the horror of what he had witnessed had almost taken the fun out of him.

In the back seat Bob too was thinking of that day. Through his brain flashed the vision of his step-brother lying wounded and bleeding on the steps of the Bar-Z ranch house. It wasn’t a picture a fellow could shake off easily and he was wishing that Jim was not going to be in this, whatever was ahead of them. To be sure, under the splendid care of the medical men and surgeons of the Don’s people, his Buddy had healed and recovered with remarkable speed, but just the same being a target was a hazardous business and one couldn’t expect to get off so easily very often. He whistled softly and determined that he would keep his eyes open and if possible shove Austin into the background. The plan looked good to the boy, and then he thought of something which seemed even better. When they came down he’d suggest that his step-brother fly on home and explain the matter to his father who could get a number of the men on the K-A together and join the deputies at the lower ranch. That was a great idea, and an even better one was to propose that Jim get in touch with Don Haurea. From this highly capable man’s laboratories something very effective could be accomplished. Bob had no thought of what the Box-Z owner would do, but since the difficulties of the summer he too had paid a visit to the subterranean department and had seen the workings of the super-television-radio. It was an awe-inspiring place and the young fellow knew that the proposal of getting in touch with its head would appeal strongly to his step-brother.

By this time the rugged peaks of lower Cap Rock were rolling swiftly toward them, and presently the buddies from their separate points of observation were examining the ranch through the glasses. Finally Jim located Carl Summers sitting on a projecting ledge from which he could keep a watchful eye on his territory. It struck the boy that the young deputy appeared very unconcerned. He had expected to discover Carl crouched in some out-of-the-way corner where he could not be taken by surprise, and surrounded with a battery of artillery. Touching Kramer on the shoulder, Jim pointed out the ledge where he had landed with Her Highness the day Lilly Boome and Ollie had inveigled him to give them a lift from Laville. Three minutes later the Pitcairn lighted perfectly on the strip of table rock, and Bob, eager to put his plan into operation, called:
