“So, that’s one of them, is it?” Jack burst out, himself a bit thrilled by the spectacle after having heard so much concerning the pack-mule trains said to have been adopted by the venturesome souls engaged in smuggling operations across the Canadian border.

“With the glass here, Jack, I c’n make ’em out all to the good,” declared the excited Perk—“a fairly big caravan in the bargain, the mules loaded for keeps an’ toilin’ along jest like they do down in Mexico whar motor cars ain’t so plentiful or cheap. Whee! what a sight for sore eyes that is, buddy! Seems like you’ll have somethin’ to wire Mister Maxwell after all. Nothin’ o’ a newspaper yarn ’bout that bunch, let me tell the world. Must be all o’ twenty animals in that string with several boobs mounted on hosses an’ armed in the bargain, ’cause I c’n see the sun glintin’ from guns they’re holdin’ as they ride ahead o’ the line an’ in the rear to boot.”

“That goes with the rest of the story, Perk,” said Jack as he started toward a lower altitude as though wishing to secure a better view of the moving cavalcade in order to make assurance doubly certain. “You remember we read in that clipping how they carried an armed guard along to defend the caravan in case it was held up by a bunch of hijackers. Queer how these law-breakers make war on each other in cities, the wilderness, and even along the salt water coasts.”

“Huh! got to be a part o’ the game these days,” grunted wise Perk, “jest like the fish-hawk drops down with a rush, grabs up a fat fish from the lake or lagoon and in turn is robbed by the lordly eagle. I kinder guess now that’s about where they got the idea o’ hijackin’—snatched a leaf from Nature in fact. But say, what are we goin’ to do ’bout this thing—why do you strike down closer, I want to know, Jack?”

“We ought to get a better look in, for one thing,” he was informed, “and if you could only work that little camera of mine once or twice so as pick up to a telltale picture of the caravan, it would be the finest evidence we could send by mail to Mr. Maxwell!”

“Glory! that’s a great scheme, boy—watch my smoke! I’m some photographer when it comes right down to brass tacks an’ I’ll prove it by gettin’ you the smartest pictur goin’ an’ that’s no lie either.”

Perk seemed to know just where everything aboard the big ship could be laid hold of in what he would call jig-time for almost as he spoke he was clutching the small but excellent camera that Jack owned, he being something of a crank along that particular line.

“I’m meaning to swing around once or twice while lowering the ship,” he explained to his companion so that Perk might not waste a single cartridge of film in taking a snapshot prematurely, with distance as a handicap.

“Go to it, partner,” sang out his mate quite merrily, “I’ll do my little bit when you gimme the word. Got her all fixed up for distance an’ the sun happens to be jest right—say, ain’t that a sweet sight, though with them mules cavortin’ like they might be scared by such a monster bird sailin’ over their stupid ol’ heads? An’ see the guards swingin’ around, shakin’ them guns at us like they meant to shoo us off by lookin’ fe-rocious! Zowie! but this is a heap int’restin’ I’m sayin’, eh Jack?”

“I bet you!” came the short answer, Jack being so taken up with staring at the greatly disturbed pack-train under the swinging airship that he could not find time for further words just then.
