Two of these had changed their course on first observing the divers’ boat, but when they saw it steering straight down, as if to meet or join them, they resumed their course for the island. Presently the breeze increased, and the pilot boat leaped over the waves as if it had received new life.

“It’s a bowld thing to try,” muttered Rooney Machowl, “but I’m afeard, sir—”

He was silenced by a peremptory “Hush” from Edgar. “Get down so as to be out of sight,” he continued, “all of you except the Chinamen.—You two come and sit by Dwarro.”

As he spoke, Edgar himself sat down on an oar, so as to be able to see over the gunwale without himself being seen. To those in the fleet it would thus appear that their vessel was a pilot boat returning from seaward with its skipper and two Chinamen. Whatever Dwarro’s intentions had been, he was evidently somewhat disconcerted, and glanced more than once uneasily at the calm youth who sat pistol in hand at his side directing him how to steer.

Although there was a considerable fleet of the piratical boats, they were spread out so that a space of several hundred yards intervened between each. Edgar steered for the centre of the widest gap, and his bold venture was favoured by a sudden increase of wind, which caused the waves to gurgle from the bow.

Just as they passed between two of the boats they were hailed by one of them. Edgar kept his eyes fixed on Dwarro, who became slightly pale. The click of the pistol at the moment caused the pilot to start.

“You may inform and we may be caught,” said Edgar, sternly; “but whatever happens you shall die if you disobey. Speak not, but wave your hand in reply.”

Dwarro obeyed. Those who had hailed him apparently thought the distance too great for speech; they waved their hands in return, and the boat passed on. A few minutes more and our divers were safely beyond the chance of capture, making for the mainland under a steady breeze.


Note 1. The pump used by Denayrouze of Paris, besides being very simple in its parts and action, possesses an air-reservoir which renders a cessation of the pump-action for a few minutes of no importance.
