The pulsating throb of the old engine aboard the sloop had long since ceased to make itself heard, so that they could with reason believe McGrath and his pal well on the way to their distant goal, with no sign of stormy weather to be seen in the southwestern heavens.

“How ’bout spendin’ the night here, partner?” Perk queried, as he sat contentedly smoking his favorite pipe after the manner of a man who had good reason to congratulate himself on the close of a perfect day.

“I was just thinking that over, Perk. We might be in a worse situation than this, if locality was all that mattered. I don’t believe the ’gators would keep us awake with their splashing and roaring along towards early morning, but then I’m a bit bothered thinking of the man who skipped out after having his little machine-gun duel with you.”

“You’re jest crampin’ my style when you say that, partner,” complained Perk. “That Oscar happens to be a German, we both know, an’ from what I learned about the breed when over there, they’re some obstinate, once they get workin’ in a game–hate to give it up wuss’n pizen.”

“I see you’re of the same opinion as myself, buddy,” Jack remarked, nodding his head. “You reckon there might be some chance for him to pick up a bunch of his mates and swing back here to do a little bombing on his own account. Well, we’re not hankering to try our own medicine, not if we know it, and on that account I think we’d be wise to pull out of this and find a new refuge–perhaps on some lake back from the coast where we might pick up something interesting in our line.”

“Je-ru-salem crickets! I kinder guess now you’ve got somethin’ danglin’ back o’ them words old hoss,” broke out the newly interested Perk, showing considerable animation. He was used to most of Jack’s habits and could in many instances tell that something lay hidden back of his word–something of a character to promise great happenings when followed to a finish.

That seemingly casual mention of a freshwater lake was not made without some deep meaning–Jack must have been told something very important by the Government official with whom he had gone into conference at Tampa and this was his sly way of starting Perk’s wits to working overtime in the endeavor to figure things out.

“Wait and see what’s in the wind, Perk,” said the head pilot, with a chuckle. “I promise to let you into all I know or suspect before a great while passes. Just now I’ll own up this scheme of slipping over to a certain sheet of fresh water for a change of base has a meaning that connects with our big game of Blind Man’s Buff.”

This seemed to square things with Perk, for he beamed as though pleased. Whatever Jack decided was always all right in his eyes because he felt certain that the bright mind of his comrade just could not make a blunder.

“When do we hop-off, then?” he said.
