The brig and the boat were now approaching each other on courses that converged at about right angles, the boat being on our lee bow, but drawing ahead at a pace which threatened to bring her unpleasantly near us if it did not actually carry her across our forefoot.  But as we drew nearer I noticed that, despite the continuous baling that was going on aboard the boat, she had settled so deeply in the water that she could scarcely hope to keep afloat another half-hour, and the idea came to me that if I could avoid her for that length of time I need fear no further trouble from her, for she would simply swamp with her crew and leave them to swim for their lives.  I carefully examined the shore through the telescope to see whether there was a spot on which our pursuers could beach their boat and get rid of the water by the simple process of turning her over and pouring the water out of her, but I could see no such spot; the whole shore, right out to the narrows, was steep-to, with a confused fringe of great masses of rock upon which it would be quite impossible to haul up a boat.
