Pulling Warrender's handkerchief from his pocket, he rolled it up, and thrust it between the lad's teeth. Warrender ruefully reflected that just in such a way had Jensen been gagged that morning. Then the men hauled him through the thicket towards the point of the island where Rush moored his boat.

"I say, Sibelius," remarked Rush, when they were half-way there, "I reckon we'd better not take 'en to the hut after all. 'Twill take time, and we don't know where his mates be. Better go and tell the boss all about it; he'd be fair mad if anything spoilt his game the last moment."

"What we do, then?" asked the Finn.

"We'll truss 'en up: plenty of rope in the boat; and put 'en in among the bushes. He'll be snug enough there."

He chuckled. Dismayed at the prospect opened before him, Warrender, who had hitherto offered no resistance, made a sudden dive towards the ground, at the same time throwing out his leg in an attempt to trip the bulkier of his captors. But though he succeeded in freeing one arm, and causing the Finn to stumble, he had no time to wrench himself from Rush's grip before the other man had recovered his balance and seized him in a clutch of iron.

"Best come quiet!" growled Rush, "or there's no saying what we might do to you. I've got a tender heart," he chuckled, "but my mate 'ud as soon kill a man as a rat."

Arrived at the boat, they threw him into the bottom, and the Finn held him down while Rush swiftly roped his arms and legs together. Then they carried him a few yards into the thicket, and laid him down in a spot where he was completely hidden from any one who might pass within arm's length of him.

"RUSH SWIFTLY ROPED HIS ARMS AND LEGS TOGETHER."

"Now we'll traipse through to the tower," said Rush. "He'll take a deal of finding, I'm thinking!"
