The vessel’s head was now put about, that we might stand off, the sail being reduced so as to leave sufficient only to give her steerage way, that, should any heavy wind overtake us, we might be prepared to receive it. Our light was utterly unavailing, for darker and darker still grew the atmosphere, till, without exaggeration, we were unable to see our hands held up before our faces; and it was through our voices alone that we were able to recognise each other.

“Is there a chance of any wind?” I asked of Fairburn, near whom I was standing. I thought how awful a storm would be in such darkness.

“It is possible, I think,” he replied. “At the same time, I fear no storm with this little craft.”

We were still in doubt as to the cause of the awful phenomenon which was taking place, when, as I happened to touch the companion hatch, I found that it was gritty, as if covered with dust, while our lips and eyes informed us that a shower of light subtle ashes was falling—the deck being soon covered with a thick coating of them.

“What do you now think causes the darkness?” demanded Fairburn of Van Graoul; for we were all three standing together round the companion hatch.

“One burning mountain. It is Tomboro, in Sumbawa; the land we saw in the morning away to the south,” he replied in his usual calm tone. “I thought so some time ago; but I said nothing, because I was not certain.”

“A burning mountain!” I exclaimed. “Could ashes have caused the intense darkness which hangs over us?”

“Oh yes; but we shall have something worse before long,” he observed coolly. “Ah, I thought so, here it comes.”

Even while he was speaking, a loud rushing noise was heard—the sea seemed to be bubbling and foaming up around us, and in an instant the schooner heeled over to her bulwarks, and appeared to be driving furiously onward over the water, as if she was about to go over never to rise again. Fairburn seized his speaking-trumpet, and shouted forth his orders to the crew. The helm was put up; the after-sail was taken off the vessel, and the jib shown for an instant.

“She pays off! she pays off!” was shouted by the crew, as her head was felt to turn away from the wind, and she once more rose on an even keel. Then on she flew, like a sea-bird before the furious blast, through the darkness.
