The transition from the first pallor of dawn to full daylight is very rapid in those low latitudes, and within ten minutes of the first faint heralding of day a level shaft of sunlight shot athwart the scene, which became in a moment transfigured, and all that had before been vague and illusory stood frankly revealed to the eye.  The sandbank now showed as an isolated patch about two hundred yards wide and perhaps half a mile long, with what looked like a by-wash channel of about one hundred yards wide flowing between it and the mainland, the latter being a sandy beach backed by sand dunes clothed with a rank creeper-like vegetation, and a few stunted tree tops showing behind them.  As the ship then lay with her head pointing toward the south-east, I was able, with some effort, to get a glimpse of a mile or two of the shore; and now that daylight had come I could see the surf breaking heavily all along it, and also upon the seaward side of the sandbank upon which we appeared to have grounded.
