The fog and the darkness together rendered it extremely difficult to see anything, but by dint of peering I at length distinguished several shapeless dark blotches at a distance of about fifty fathoms from the ship, arranged apparently in the form of a wide semicircle on the side of her opposite to that on which lay the sandbank.  Jones, however, was not quite right in his statement that they were closing in upon us, for they appeared to be lying quite stationary, or at least were only paddling just sufficiently to avoid being swept away by the sluggish tide that was running.  But there was very little doubt in my mind that we had very narrowly escaped an ugly surprise, and I was by no means certain that we might not yet look to be attacked.  My view of the situation was that the natives had gathered about us in the hope that, in the fog and darkness, they might be able to steal alongside and climb aboard in such overwhelming numbers as to secure possession of the deck and overpower us by taking us by surprise, and that they had been restrained from making the attempt only by the sounds of bustle and activity that had accompanied our endeavours to get the ship afloat.
