"It's no use thinking about that, Bill. We shall be a good deal more hungry before we are done; but I am so glad we have found the land and stopped going out to sea that I don't mind being hungry."
"But I say, George, if this fog keeps on how are we to find our way back to Gravesend?"
"The only way will be, Bill, to keep quite close to the edge of the mud—just as close as the boat will swim. That way, you know, we must come to Gravesend at last."
"So we must. I didn't think of that. You have got a good head, George, you have. I should never have thought about the way to find the bank if it hadn't been for you, and might have gone on floating and floating till we was starved."
"This fog can't last forever, Bill."
"No, but I have known them last a week in London."
"Yes, but not in August, Bill."
"No, not in August," Bill assented; "but you see these here fogs may last just as long down here in August as they do in London in November."
"I don't think so, Bill. Anyhow it doesn't matter to us; we have got the land for a guide, and I hope we shall be back in Gravesend before it's quite dark."
"But if we don't, George?"
