1911 Encyclopædia Britannica/Sagar

SAGAR or Saugor Island, an island at the mouth of the Hugli river, in the Twenty-four Parganas district of Bengal. The word means “ sea ”; and, as being the place where the sacred stream of the Ganges is believed to mingle with the ocean, the island is one of the most frequented places of Hindu pilgrimage in all India, the time for the greatest annual gathering being in January. On the seaward face is a lighthouse, and farther out are the Sandheads, the cruising-ground of the Calcutta pilots.
