sectors of our wide country look alike to energetic Secret Service agents especially when they have magical wings with which to annihilate space and carry them through cloudland at a hundred miles and more an hour.

It looked very much as though their excellent record was being fully appreciated at Headquarters for there had come to them a wonderfully equipped new ship, carrying many lately discovered and new inventions calculated to lighten the labors of the man at the controls as well as to secure a degree of safety never before attained in any craft.

Jack was heading for the home port, quite satisfied with the finishing check-up of the amazing attributes of their new acquisition, and as for Perk, he could hardly contain himself, such was his enthusiasm in connection with their trying-out process.

“Beats anything that carries wings,” he vowed in his characteristic fashion, “and it’s bound to be a poor day for any guy who thinks he c’n get away from this race hoss o’ the skies. See how she snorts on her course will you, partner, and us agoin’ at mor’n a hundred an’ thirty right now! This is the life for me, an’ I wouldn’t care much if my legs got so cramped I couldn’t walk a mile—some birds are like that, I understand, buzzards f’r instance fairly wobble on the ground but able to put the kibosh on most other feathered folks when they take off in their clumsy way.”

Jack did not show much desire to keep up the conversation—the fact of the matter was he felt more or less tired after a long day in the clouds and much preferred to pay strict attention to the many dials on the black dashboard just in front, with which he was by degrees becoming familiar.

The afternoon was drawing near its close, with the sun drawing closer to the mountainous horizon off to the west. So after swinging on their way for half an hour they were able to glimpse their destination which was the Cheyenne, Wyoming, airport.

“Keep up your bluffing when we land Perk, remember,” warned Jack as he started to circle at a height of a thousand feet and could see a number of people running this way and that, undoubtedly in their endeavor to be close by when their landing gear struck the ground.

This wonderful new plane, and the mysterious pair of pals handling it had continued to excite the curiosity not only of pilots using the field, but aviation bugs who haunted the place as well. These folks were enthusiasts over the exploits of noted flyers, but not venturesome enough themselves to wish to become pilots, even though they were of the right calibre. However, they knew considerable about ships and their furniture so as to be able to appreciate anything exceedingly novel along those lines.

“Watch my smoke, partner,” said Perk complacently enough. “I’m not agoin’ to let any o’ that mob crab my game. Men in our class don’t go around doin’ their stuff in the open, like they was magicians throwin’ a fit. We got to know how to mix things a heap an’ pull the wool over the eyes o’ the crowd. So far as they need to know, we’re jest a couple o’ guys out for a lark an’ with shekels to burn.”

“That’s the ticket Perk, keep the racket going up to the time we pull out of Cheyenne no matter which way we climb. Well, here goes to knock our tail on the ground again then for a bite of supper at the Emporium and a look in at some show. I’m getting a bit tired of this inaction, to tell you the honest truth. I reckon both of us will be glad to get our next orders and cut loose with our nobby ship.”

“You said a mouthful buddy that time,” observed Perk as he raised his hands with the intention of removing the earphones since they were at the end of their afternoon check-up, delightfully happy because their plane had shown its exceedingly strong points.

Now they were circling for the last
