To Jack’s mind they looked like a pair of gigantic fireflies gone loco with excitement and carrying on in the most astonishing manner. Indeed, he could easily picture it as a wild dance of make-believe insects on a greatly magnified scale.

Of course Jack never had the slightest doubt as to what all this mystifying activity must be–the two extremes of the smuggling fraternity were exchanging signals–each and every movement had a meaning of its own and conveyed such information as was most valuable to the business in hand–in Jack’s mind it was as though the conversation might be running something after this fashion:

“Well, here we are on hand according to promise, with a full cargo of the finest wet stuff you ever had drop down on your coast. How does the land lie over there?”

“Coast all clear–we will start the fleet out to lighten your cargo right away–keep the beacon burning so they’ll make a straight line to your anchorage, which will mean a saving of time.”

“We get your meaning–glad you are so prompt to send back word–come right along and get your invoice–the more the merrier, boys. Wind getting rougher, and we ought to be off this shallow shore before it swings around any more. Don’t hold back–Merry Christmas to you all, boys!”

Perk on his part was also trying to keep tabs on all that was going on, not neglecting his duties with the controls, it can be set down as certain. He twisted his neck and cast swift glances first to the right and then in the opposite direction, fascinated by that flashing beacon conversation.

“By gum! if they ain’t holdin’ a regular confab with them lights,” Perk was telling himself, delighted with his opportunity to witness such a proceeding, knowing as he did what this all meant to himself and Jack. “That guy on shore is sure some punkins about this signal layout–works jest like a Boy Scout might, sending a message across to another o’ the troop standin’ on top o’ a high peak–makes me think I’m back on the front, with Signal Corps men wigwaggin’ for all that’s out. Huh! There goes them twin lights, showin’ the chinnin’ must be over with both sides posted on the program. Say, ain’t this the boss job though? I guess I never did get half as much fun outen any game I tackled before.”

Just then Jack signalled that he wished to handle the stick once more, which the other was indeed not sorry for, since it began to look as though they were close to a critical moment when considerable skill would be required in manipulating the ship so as to accomplish their ends without unduly alarming those they spied upon.

Already they had managed to collect a certain amount of valuable facts which were only guessed at previously, so cleverly had these transfer bases been kept concealed from the most skillful of the Government agents. Perk himself felt confident that they were as yet only on the threshold of still more important discoveries.

It was one of Perk’s peculiar little eccentricities that he could do better thinking if only he had a bit of chewing gum between his teeth, just to keep some muscles at work, he said, and in some mysterious fashion having this energy pass from his working jaws to his brain and hasten its activities.
