"Give it up," he declared. "All the same——"

"Dash it all, I've tumbled to it," interrupted Dacres. "You were that curly-headed Sea Scout I met at Haslar Creek three or four years ago. I believe you were the means of enabling me to get a yacht off my hands."

"And incidentally the means of getting me my commission," added the ex-Tenderfoot. "And Osborne is on board too. There he is: officer of the watch. If it hadn't been for the experience we gained on board the old Petrel, I don't suppose we would have been here."

The reverberations of the tremendous detonation were straining his ear-drums almost to bursting-point. Wreaths of pungent smoke, caught by the vicious blasts that eddied over the deck, obliterated everything from his vision and made him gasp for breath like a drowning man. His brain seemed benumbed by the concussion, his legs were on the point of giving way until he almost unconsciously grasped a guard-rail within arm's length.
