“He’ll be dancing a hornpipe in a week,” prophesied Captain Toby; “the Specific has never failed.”

But if he could have seen Mr. Jukes carefully drop the bottle overboard as soon as he reached the shore end of the dock, his opinion of him would have fallen considerably. As it was, the old seaman was loud in his praise.

“Think of him, the skipper of a big corporation and all that, wisiting us on the Wenus!” he exclaimed. “Why, Jack, that’ll be something to tell about. The great Mr. Jukes! Maybe this’ll all lead to something! If the Specific works like it did on Cap’n Joe Trotter, he may make me his physician in ordinary.”

“Let’s hope it won’t work the same way on him that it did on Captain Zeb Holliday,” said Jack with a smile.

“Huh! That deck-swabbing lubber!” cried the captain, with intense scorn. “He drank it instead of rubbing it in, although the directions was wrote on the bottle plain as print. But, Jack, lad, why didn’t you take that check? Consarn it all——”

“It’s no good talking about it, uncle,” said the boy, cutting him short; “I couldn’t take it; that’s all there is to that.”

“Confound you for a young jackass! Douse my topsails, but I’m proud of you, lad!” roared the captain, bringing down a mighty hand on Jack’s shoulders. “And now let’s pipe all hands to supper.”

Two days later, Jack happened to pass the dock where the Titan liner lay. She was taking aboard her cargo from a pipe-line—crude, black oil destined for Antwerp. Because of the adventure in which he had participated alongside her, Jack felt an interest in the ugly, powerful tanker. As he was looking at her, he noticed some men busy at the tops of her squat steel masts.

All at once they began to haul something aloft. What it was, Jack recognized the next moment. It was the antennæ of a wireless plant. They were installing a station on the ship, which bore the name “Ajax” on her round, whaleback stern.

Jack’s heart gave a sudden leap. A great idea had come to him. Mr. Jukes owned the Titan Line. The ship-owner had said to him only two nights before: “Remember, I’ll always stand your friend if I can. Never hesitate to call on me if you need anything at any time.”
