Signs are all around us, if we know where to look. The ability to read and interpret signs is particularly useful to navigators and those who make their living on the water. In fact, the ability to read water can mean the difference between life and death, especially when strong tidal currents are involved. Of course, there are those who take water-reading beyond the ability of even the most experienced sailors. Traditional Arab navigators called this knowledge the ''isharat.'' Pacific islanders call it ''kapesani lemetau''-the talk of the sea or water lore. Those who posses such knowledge have been baffling Westerners for centuries with their seemingly preternatural ability to understand the water.
