“Here’s another sheet giving the ship’s position at that moment,” Joe continued; “also her course and speed.”

“And you answered?” demanded Halstead.

“Just as I started to, the wireless at Beaufort broke in. It seems that Mr. Seaton is at Beaufort, and that he heard, at once, of the trouble. Here is Mr. Seaton’s order.”

Joe Dawson held out another sheet, on which he had transcribed this wireless message:

Halstead, Lonely Island: Clodis is my man on important matter. Get him off ship, and with all speed. Take him to Lonely Island, where I will arrive with surgeons and nurses. Get all his baggage and papers off with him, and take greatest care of same. Whole thing plotted by enemies. If they succeed it spells ruin for me and more than one tragedy. I depend on you boys; don’t fail me! Act at full speed.

(Signed) Powell Seaton.

“That comes from Mr. Seaton, all right,” nodded Captain Tom. “That’s his private signal, below his name, that he told us to look for on all orders of his. Now, let me have a look again at the position and course of the ‘Constant.’”

After studying the dispatch intently, Captain Halstead nodded to his chum to take the wheel. Facing about, Tom swung open the small chart-case secured to the top of the deck-house. With a small, accurate pocket rule he made some measurements.
