“Safe to send half of fleet to Baltic to-morrow night. Order submarine and several destroyers close into Helgoland at same time—this to make imminent attack apparent, so enemy may not learn of other move and attack in force.—Hastings.”

The message placed in the hands of the operator, the boys returned to their own cabin. As they made their way along the deck they saw Hardy loitering near the wireless room.

“He’ll hear it, all right,” said Jack, with a grin.

“How do you construe that message?” asked Frank.

“Well,” replied Jack, “let’s see if we can’t figure it out. Say the Germans, having been furnished with the text of the message—fake though it is—believe half the British fleet has started for the Baltic. They will figure that their own strong fleet can easily destroy the remaining half of our fleet. Therefore, when they believe it has been divided, they will attack. Lured from beneath the protection of the heavy shore guns, we shall make short work of them.

“I figure that the submarine and destroyers will approach nearer the port to flash word of the German advance. Besides, their appearance will further strengthen the belief of the Germans that half of the fleet has sailed—particularly in view of the false message, for it would be the natural thing to do if half the fleet really were going away, as it would keep the Germans from attacking.”

“I see what you mean,” declared Frank. “And I guess that is the way Lord Hastings has figured it out.”

“I’m sure of it,” was the reply. “But come on deck, and let’s see if we can see what use Hardy will make of the information he has obtained.”

Moving stealthily along the deck, the lads saw the sailor making his way toward Lieutenant Taylor’s cabin. There he slipped a piece of paper through the window. Then he loitered near.

There came a slight tapping on the window, and the sailor again approached it. The boys heard the lieutenant’s voice.
