The hundred and sixtieth meridian of east longitude bisects the island of Guadalcanal. The same meridian, nearly a thousand miles to the north, narrowly misses Ponapé, in the Caroline Group. Truk lies west of Ponapé, Kusaie east-southeast. Six hundred miles to the southeast and below the line is Nauru. Seven hundred miles west of Nauru, but above the Equator, is a tiny island with a formidable name: Kapingamarangi.
