“Well, is he to come?” demanded Billy.

“Don’t be so impatient,” reproved Frank. “Listen to this. I got it this morning.”

He drew from his pocket a telegram and the boys all shouted with laughter as he read it aloud. It was characteristic of their old comrade.

“Have sold the tug and will be in White Plains to-morrow. Ben Stubbs, (skipper retired).”

“Good for him,” cried Billy, as the three boys made their way back from the living quarters to the aerodrome, “he’s a trump.”

“I don’t know of anyone I would rather have along in an emergency and on such an expedition as this, his experience and resourcefulness will be invaluable to us,” declared Frank.

The next morning Frank and Billy left the others busy at the aerodrome applying the waterproof compound to the Golden Eagle II’s planes and started for town behind the venerable old steed that Billy had christened “Baalbec,” because, he explained, “he was a remarkably fine ruin.” The first train from New York pulled into the station just as they were driving into the town of White Plains and a minute later the ears of both boys were saluted by a mighty hail of:

“Ahoy there, shipmates, lay alongside and throw us a line.”

The person from whom this unceremonious greeting proceeded was a short, sun-bronzed man of about fifty. He had an unusual air of confidence and ability and his mighty muscles fairly bulged under the tight-fitting, blue serge coat he wore. He carried an ancient looking carpet bag in which as he explained he had his “duds,” meaning his garments. The greetings between the three were hearty and after Frank had made a few purchases up-town and Ben had laid in a good supply of strong tobacco they started for the aerodrome.

As they drove down the street a thick-set man, with a furtive sallow face, came out of a store and as he did so saw the boys. With the agility of an eel he instantly slipped into a side street. But not so quickly that Billy’s sharp eyes had not spied him and recognized him.
