"But it looks as if we are being opposed from the very start," objected Tom. "Look at this visitor and the note he left. That must indicate that there is a gang working against us. I'm a peaceful, orderly citizen and not at all inclined to start anything."

"Yes, he is!" laughed Arnold. "Look at the way he put the rollers under the gang of thugs at our camp at Mackinac Island!"

"Now, boys," continued Jack, beckoning Arnold to silence, "if any one of you wants to go back, he can have the chance. We're going to Pascagoula and also to Biloxi. At either place one can get the Louisville & Nashville railroad for home. Think it over. If you want to try for the Spanish Treasure Chest, stick. If not, you are at liberty to go home at any time we make a port."

At that instant the lads were startled to hear the hail:

"Launch ahoy! Keep off!"

"Port your helm," commanded Jack to Arnold who was at the wheel.

Dimly the boys made out the bulk of a schooner on their port bow, her sails slatting and rigging flying as she came up into the wind. As the Fortuna fell off they looked at the schooner and saw the main boom swinging across the deck, strike a man standing near the rail.

"Man overboard. Give me a line," cried Arnold, springing over the rail without stopping to divest himself of his clothing.
