"But that's no novelty," objected Roy, "we've been up 5,000 feet already, and——" "But we're talking about a tour through cloudland," burst out Jess, unable to retain the secret any longer, "a sort of Cook's tour above the earth."

"Wow!" gasped both boys. "There's nothing slow," added Roy, "in that or about you two. And, incidentally, just read this letter I got this morning, or rather I'll read it for you."

So saying Roy produced from his coat a letter closely written in an old-fashioned handwriting. It was as follows:

"My Dear Niece and Nephew: No doubt you will be surprised to hear from your Uncle Jack. Possibly you will hardly recall him. This has, in a great measure, been his own fault as, since your poor father's death, I have not paid the attention I should to my correspondence.

"This letter, then, is to offer what compensation lies in my power for my neglect. Having read in the papers of your wonderful flying feats in Nevada it struck me that you and your young friends might like to pay me a 'flying trip,' making the excursion via aëroplane.

"We are to have some flying contests in Marysville during the latter part of the month, and you might care to participate in them. Of course I expect your Aunt Sallie to accompany you. Hoping sincerely to see you, I am

"Your affectionate uncle,
"James Parker.
"Marysville, North Carolina."

As Roy concluded the reading the quartet of merry youngsters exchanged delighted glances. As if by magic here was an objective point descried for their projected motor flight.

"Well, that's what I call modern magic," declared Jimsy glowingly; "consider me as having accepted the invitation."

"Accepting likewise for me, of course," said Jess, shaking her black locks and blinking round, expectant eyes.
