“Yes indeed,” went on Harry seriously, “he’s such a coward that he would have fainted if we had even suggested coming up with us to him.”

“Well, I’se a berry brave nigger and dat’s a fac’,” proudly said Quatty rising to the bait, “them no ’count southern niggers ain’t got no real courage no-how.”

So well did Harry’s diplomatic admiration work that before they had been afloat in the upper air for half an hour more Quatty was seated on one of the transoms holding onto a strap provided for the purpose and piloting Frank as the ship forged steadily along into the wind, her engine running without a skip or a start.

It was a marvelous panorama that lay spread out far below them. Their bird’s-eye view showed them immediately beneath the floating craft the myriad green-clad islands of the archipelago threaded by bands of sparkling blue water. Soaring in the air about them, but at a respectful distance, and doubtless marveling at the invader of their realm, were kitty-hawks and fish-eagles and sometimes even the rare Everglade kite. If it had not been for the speed they were going nothing would have pleased Harry better than to get out a rifle and try a little target practice at the myriad bird-life that soared beneath and around them.

But it was not so much the immediate scene, beautiful as it was, that gripped the attention of the voyagers. Far in front of them lay a broad, dark band of trees that they knew marked the mainland and was the thick belt of cypress trees that gives its name to the Big Cypress Swamp. Beyond this again lay a scene that made their hearts beat high. It was a vast, an apparently illimitable stretch of brown prairie, looking from that distance very much like our western plains viewed from a mountain top. In the golden glow of the afternoon it shimmered and shone hazily like a magic land. Here and there patches of dark cloud-like blue dotted it and these the boys knew were the islands that are scattered at more or less frequent intervals among the watery wastes of the ’glades and on one of which, with a catch of the heart, they realized lay the object of their long quest.

CHAPTER XVIII.
A NIGHT ALARM.

Quatty, quite recovered now from his first terror, and almost aggressive in his newly-found courage, sat by Frank’s side directing him as well as he could for, as he explained, he would not be able to get his bearings till they had passed the cypress belt and were above the Everglades themselves. Every now and again, however, he would give the young captain a steering direction.

“A bit mo’ eas’ by sout’,” or “Hold a bit to de sout’ sout’ eas’, massa.”

“What are we making, Frank, do you estimate?” inquired Harry, as the ship rushed through the air.

“About ten miles,” rejoined the other, “the wind is dead against us.”
