“But you can still send messages from the ‘Restless,’” hinted Powell Seaton.

Tom Halstead bounded for the door of the dynamo shed with a sudden exclamation of dread.

“We can use the boat’s wireless,” nodded Joe, following, and speaking over his shoulder, “unless the same crowd of rascals have broken into the boat’s motor room or cabin and played us the same trick there.”

In the big sitting room, beside the large open fire-place, was a pile of long sticks of firewood. Tom Halstead stopped to snatch up one of these, and Joe quickly followed suit.

“I’ll go down to the boat with you, boys,” said Mr. Seaton, who had followed them. “If there’s anyone around to put up a fight you’ll want some help.”

But Captain Tom, acting, for the moment, as though he were aboard the yacht, suddenly took command.

“Mr. Seaton,” he said, “you’d better remain here to guard your unconscious friend. Doctor, wake up! Better go in and send Hank Butts out on the trot. We’ll take him with us.”

Dr. Cosgrove, awaking and realizing that something important was happening, swiftly moved off to the sick-room. Hank was speedily out with his comrades. 49

“If there are rascals on this island, who have designs against you, Mr. Seaton, then mount guard over your friend,” Tom added. “Better be in the sick-room at any moment when Dr. Cosgrove leaves there. Hank, get a club from that pile. Now, come along, fellows, and we’ll see what infernal mischief may have been done to the ‘Restless.’”

With that, the young skipper bounded out onto the porch, thence running down the board walk toward the dock.
