“I expect it is lava,” Stephen said. “There are lots of volcanoes among these islands, and I believe that high hill is one, and that if we were to climb up we should find there was a crater there. You see we are just in a line with that gap, and this rock goes exactly in that direction. I expect that in some eruption ever so long ago, the crater split there, and the lava poured down here into the sea.”

“Very likely that is it, Stephen; it must have been a long time ago anyhow, you see there are big trees growing on it.”

In ten minutes they arrived at the spot where the wreck [pg 106]had been; her keel remained there, but with this exception she had entirely disappeared. They took another look among the wreckage, cut off some lengths of rope and coiled them up, and also a sail, which the sailor pronounced to be a top-gallant sail. This they rolled up, fastened it by short pieces of rope, and then, the sailor taking the middle and the lads the ends on their shoulders, they carried it to what they already called their “well”.

“We will set to work at once to rig up a tent under the shade of these trees,” the sailor said, “it will keep the night mists off better than branches; and we will bring another sail over to cover the ground and keep the mist from rising inside.”

“What are we going to cook our junk in?” Joyce asked suddenly.

The sailor looked at his companion in dismay. “Dash my timbers,” he said, “I never thought of that; that is a go. Perhaps we can manage it in the native way: they boil things by putting water into a big shell, and dropping hot stones into it until it boils. We have not got any shells, but we might find a hollow in the rock that will hold water.”

“That is all very well, Wilcox; but how are we going to heat our stones?”

“You have done me there, Master Stephen,” the sailor said, in a tone of utter disgust; “we have not got flint or tinder.”

“We might manage the tinder easily enough,” Stephen said, “by using rotten wood; but tinder is of no use without steel. We shall have to eat our biscuits without meat, Wilcox, unless we can light a fire by rubbing two sticks together.”

“That ain’t to be done, sir; I have seen white men try it over and over again, and I have tried it myself, but it ain’t no manner of good. The Almighty has given us a lot of knowledge that he has not given to these black fellows, but he has [pg 107]balanced it up by giving them the knack of lighting a fire which he has not given to us. I never heard of a white man who could make fire in that way.”
