"It might, of course," admitted the skipper; "but, all the same, I do not believe it was.  For the people who supplied Captain Harrison with false information would surely know enough of him and his methods to be certain that, failing to find anything in the nature of a slave factory at King Olomba's town, we should not leave the river again until we had thoroughly explored it; and if they knew the river at all they would also know that the factory on the Camma Lagoon could scarcely be overlooked by us.  No; in my own mind I feel convinced that the factory which we destroyed to-day was not the one in which those fellows are interested; there is another one somewhere in the river; and I will not leave until I have discovered and destroyed it.  But that only brings me back to the point from which I started, and once more raises the question, Why did they cast us away within a few miles of this other factory which I am persuaded exists?  Is it that the place is so strongly fortified that they are confident of our inability to take it? Or is there something else at the back of it all, of which we have not yet got an inkling?"
