BACK TO BRIGHTON 239 The Brighton Boys in the Submarine Treasure Ship CHAPTER I NEW WORLDS TO CONQUER "Look, Dick, what's that out there in the water right on the line of that ventilator?" Jay Thacker, ensign in the Navy of the United States, veteran of many months' service in the grand fleet of the American Admiral Sims in European waters, grabbed his old chum Dick Monaghan by the coat sleeve and pointed a long lean finger out to the open expanse of sea. The two bronzed boys, rugged and fit after their experiences of the Great War, erect and sturdy looking in their natty uniforms, stood on the aft deck of the giant _Leviathan_, United States army transport, once the pride of the German merchant marine, now a carrier of men and merchandise sailing under the Stars and Stripes.
