The following day was a busy one for the two pals. Each had a regular programme to follow, Jack having made out two lists of important things absolutely essential to the carrying out of their plans.

As usually happened he left to Perk the task of seeing that the ship was fully supplied with all the fuel and oil she was capable of carrying off in making an ascent; some of which could be stored in the wings, purposely provided with stowage room for such occasions.

Then when it came to taking aboard a stock of provisions, such as would not require cooking, trust Perk for having a complete understanding as to these requirements—he possessed such a vast knowledge of what was good for a hungry man, not in a position to start a campfire, that when he put the last of their stock away aboard the plane it looked as if they might be getting ready to explore the Arctic regions, where nothing but driftice was to be met, and no chance of having a fire either for cooking or comfort.

Jack, meanwhile did his part, making carefully arranged plans, with alternate makeshifts such as could be taken up in case unsurmountable obstacles baffled them in the one chosen for the start—with Jack it was always part of his strategy to have several “strings to his bow,” and never if possible “put all his eggs in one basket.”

When wearied after all the tramping he had done in accumulating such a vast pile of material, Perk dropped down into a chair alongside his chum—who was still doing the finishing touch to his programme—he heaved a sigh as of contentment—as a rule Perk was not a vigorous walker, preferring to go by airplane, motorcar, or bus; perhaps even by stage if necessary, so that such unusual exercise told heavily on his muscles.

“Get through with your list, partner?” queried Jack, shoving aside his papers, as though he too had had quite enough of work for one day.

“Sure did, matey,” came the satisfied reply; “we’re done loaded up to the limit, an’ then some. Hope the ole gal don’t fight shy o’ liftin’ sech a rummy cargo; but so far we aint never had her balk on us. How yeou gittin’ on with things, Jack?”

“Making good progress,” came the steady answer. “I’ve learned that we’ve shouldered a whopping big job this time; and still things keep cropping up, that make it necessary to go back and change matters some. But I’ll be in fine shape by tomorrow noon, I figure.”

“Kinder reckon on makin’ the jump then, air yeou, boss?” demanded Perk.

Jack shook his head in the negative.
