"Are there any other channels through the reef?" the captain asked.

"I do not know," Will replied. "We have never explored it very far, either way; but as I should think, from the action of the Malays, that they did not know of this, they might not know of any other, did it exist."

"Then," the captain said, "I will warp the brig out through the channel again; and anchor her, stem and stern, across it outside. They will find it as hard to attack us, there, as they did before. Then, when the breeze comes, we will slip our cable and run for it. She is a fast sailer; and can, I think, get away from the pirates, even with their sails and oars. Besides, by shifting the long gun and two of the others to her stern, we can give it them so hot that, even if they are the fastest, we may sicken them."

"I do not know, sir," Will said. "They would be likely to hang about you, until the breeze drops; and then to attack you on all sides at once. If we could but keep them from coming through the channel, in pursuit, we should be safe."

"Ah! But how on earth are we to do that?" the captain asked.

William Gale was silent for a minute or two.

"Have you plenty of powder on board the ship, sir?"

"Plenty--we use it for barter."

"It seems to me--" Will went on, "--that if, before sailing, you could sink a couple of barrels of powder in the channel, with a fuse to explode them, a few minutes after we had left; the Malays would be so astonished, at the explosion, that they would not venture to pass through."

"Your idea is a capital one," the captain said, warmly; "but how about a fuse which would burn under water?
